Ultra-Low Sintering Temperature Electroceramics - for 5G and IoT Applications

Plenary Speaker - Heli Jantunen

ABSTRACT: The number of connected devices (IoT) is predicted to increase to 50 billion by 2020. This prediction however does not take into account advances in internet and device technology (Cisco IBSG 2011) and thus the growth can be much faster. At the same time the 5th Generation Telecommunications Technology (5G) is emerging to provide higher data rates and bandwidth and lower response times. Both of these happening coincidentally is expecting fast development of electroceramics meaning new compositions, fabrication and 3D integration approaches.

In the last decade over 200 electroceramic compositions with ultra-low sintering temperature have been developed. Most of these below can be sintered in the temperature range of 300-700°C providing also an opportunity to make modules with tape casting and co-firing. In addition, several compositions needing no sintering at all are reported and some components introduced. The approaches provide interesting new ways to realize devices for 5G and IoT with the recently reported advancements as follows:

- low energy consumption and low-cost investments
- multimaterial modules
- integration with temperature sensitive materials and devices including plastics, semiconductors and paper
- totally new way to make "all ceramic" composites
- additive manufacturing with 2D and 3D printing
- accurate component dimensions by zero-shrinkage or room temperature fabrication methods
- feasible to even small scale production

These opportunities available with ultra-low sintering temperature electroceramics are discussed against the future needs by 5G and IoT highlighting also what should be next steps.

Nondestructive Evaluation of Embedded Piezoceramics by Thermal Wave and Thermal Pulse Methods

Invited Speaker - Dr. Gunnar Suchaneck

ABSTRACT: Structural components with embedded piezoelectric sensors and actuators find application in structural vibration suppression and noise reduction, energy harvesting, structural health monitoring, precision positioning, etc. During fabrication, piezoelectric transducers are supposed to mechanical and thermal depolarization and microcrack formation. Therefore, non-destructive evaluation of the polarization state is required for quality inspection. A periodic thermal excitation of the piezoelectric material gives rise to a pyroelectric current which carries information on the polarization profile. In frequency domain, the Laser Intensity Modulation Method (LIMM) is well-established (Lang and Das-Gupta 1986). Thereby, thermal oscillations are generated by a periodically modulated laser beam. When thermal pulses are applied with a pulsed laser, the signal is recorded in time domain, but it can be Fourier-transformed and analyzed in the frequency domain similar to LIMM (Mellinger et al. 2005). Recently, we have demonstrated that LIMM is promising for the non-destructive evaluation of the polarization state and thermal interfaces of piezoelectrics embedded into low temperature co-fired ceramics (LTCC), epoxy resin and polyimide, polyamide 6 as well as high-pressure die-casted Al (Suchaneck et al. 2012, Eydam et al. 2015). At low modulation frequencies, the pyroelectric response of PZT is governed by thermal losses to the embedding layers. In this case, the sample behavior can be described by a harmonically heated piezoelectric plate exhibiting heat losses to the environment characterized by discrete relaxation times or by their continuous distribution. Thermal relaxation characterizes the thermal contact and, thus, enables locating lamination failures. The first sample type investigated in this work, was a commercial Smart Materials Macro-Fiber Composite piezoelectric actuator. Here, the real and imaginary parts of the pyroelectric current spectrum fits to a 1-D heat loss model with Cole-Cole relaxation. The maximum relaxation time provides the interfacial thermal conductance of about 100 W/m2K. A second, much smaller relaxation time corresponds to an interface thermal conductance of approximately 30 000 W/m2K which is characteristic for interfaces between two thin metal sheets. ANSYS simulation reveals that the good agreement with a 1D-model is attributed to a significant blurring of the temperature field by the metallic electrodes and as a consequence a small lateral component of the temperature gradient at the piezoceramics/epoxy resin interface, i.e. heat conduction through this interface can be neglected. A comparison of thermal relaxation times calculated for ideal thermal contact with experimental ones allowed disclosure of lamination failures. The second sample type was an integrated low temperature co-fired ceramics/PZT module. Here, the laser light is absorbed in a surface layer of about 80µm thickness where the thermal oscillation takes its origin. The relaxation time of 0.16 s takes its origin in an uncertain thermal contact between the LTCC and the embedded PZT plate. The corresponding interface thermal conductance amounts to about 170 W/m2K at both the top and the bottom surface. Above 100 Hz, the penetration depth of the temperature oscillations into LTCC becomes less than the laser light absorption depth determined by optical transmission measurements on very thin LTCC samples. Consequently, the simplified model of harmonic heating from a very thin surface layer is no more valid. The thereby recorded pyroelectric current takes an additional time lag, i.e. a property corresponding in electrical engineering to an inductive behavior. The third sample was a thermoplastics-compatible piezoceramic module. The pyroelectric current spectrum of a thermoplastics-compatible piezoelectric are well described by five single relaxation times. The first is unknown, the other are related to thermal losses of the sample top and bottom to the environment, to thermal losses through the PZT electrode/thermoplastics interface, to bulk thermal conductance of the thermoplastic and to the metalized PZT surface/ meandered Ag-paint electrode interface. For Al die-casted piezoceramic modules, the pyroelectric current spectrum allows to distinguish centre-positioned from off-centre positioned transducers (Eydam et al. 2015). The pyroelectric current measured in time domain was Fourier-transformed and corrected by the transfer function of the measurement set-up to account for the influence of the amplifier settings. The resulting pyroelectric spectrum is analyzed then in the frequency domain as already illustrated. However, in practice, we have to account for the bandwidth of the preamplifier connected with the large capacitive load of the sample, that is we are able to reconstruct the frequency spectrum only in a certain frequency region. In summary, thermal wave and thermal pulse methods are a suitable tool to control the quality of both poling and embedding of piezoelectric ceramics. They enable to evaluate the polarization state, to characterize thermal interfaces and to indicate lamination failures.

Thick-Film Pastes for Special Applications

Invited Speaker - Uwe Partsch

ABSTRACT: Thick film pastes have been used for many years for the manufacture of hybrid microsystems, circuit boards and sensors. Screen printing technology is still the printing technology of choice also for new applications apart from traditional materials and processes. However, the thick-film pastes used must be adapted accordingly. Challenges include, for example, the adaption of the solid constituents of the pastes to obtain required functional characteristics, to avoid chemical reactions with special substrate materials while firing or to define a requested coefficient of thermal expansion. By selecting and modifying the organic paste components, it is possible to customize the printing properties of the pastes. Further requirements concern, for example, the necessary burnout behaviour of the organic components at specific temperatures or at special atmospheres such as in nitrogen or vacuum. The presentation gives an overview about the topic. The results of various projects illustrate the development cycle for specialized thick-film pastes at Fraunhofer IKTS.

Uwe Partsch is head of the Hybrid Microsystems Department and the Thick Film Technology Group at Fraunhofer IKTS, Dresden/ Germany. Scientific topics concern various aspects of ceramic thick-film and multilayer technology, in particular LTCC technology. Examples are the development of various thick-film and LTCC-based components as well as material and technology development for 3D printing of functional structures and components.

Critical Evaluation of Additively Manufacturing Electrical Ceramics for Dielectric Resonator Applications

Invited Speaker - Brandon Cox

ABSTRACT: Additive manufacturing is gaining popularity in materials research and manufacturing due to the ability to generate complex geometry parts from computer-aided 3D designs. These designs include shapes that are not achievable by traditional subtractive manufacturing, and more specifically for ceramic material systems. The complex geometry capability, more frequently known as near-net-shape (NNS), sets this method apart from traditional methods such as pressing and casting. However, there are challenges that arise by using this method, as well as limitations. Complex printed shapes almost always have a higher surface-area-to-volume ratio compared to traditionally formed parts, and it can be very difficult, if not impossible, to perform any post-sintering surface treatment on printed parts. If you press and sinter a pellet, it is relatively easy to polish the surface as well as the underlying bulk material, but this cannot be done with NNS printed parts. There can be inner surfaces that cannot be reached, and therefore must exhibit the final surface after being printed. With this specific limitation, there needs to be much more understanding and control of the interactions between the parts and the sintering environment/atmosphere (e.g. grains on the surface may sinter differently than ones in the bulk). Also, the sintering stresses associated with NNS parts will be much different than those of the bulk monolithic pieces. Printing multiple ceramic materials poses its own specific challenges as well. There is much concern with the printing method used, and the transition point, or gradient, between materials. These areas of concern are being considered in this work, and optimistically being improved for a better ceramic product via control over specific materials during the printing process. Customization of ceramic components will be demonstrated as a step that can be taken to further in tailoring the printing process to meet the specific needs of a part’s final application. One application for additive manufacturing (AM) of ceramics is with wireless technologies using dielectric resonators. Wireless technologies have become ubiquitous in modern life and are gaining momentum for their technological advancement. Dielectric materials are typically the material of choice when developing specifically tailored microwave dielectrics for wireless applications [1]. Across the entire electromagnetic spectrum, there are a variety of frequency bands that are covered by the various wireless technologies, such as those used with mobile phones, communication satellites, radar and car sensors, across frequencies ranging from 800 MHz to 30 GHz. One of the large concerns with wireless technology is the size of the antennas used and their anticipated satisfactory performance. The selectivity and stability of these components are essential for ensuring that the signals produced are restricted to their predetermined frequency bands and to control the introduction of unwanted signals from outside sources. Some common devices that require this technology are satellites and mobile radio communications, in which they utilize narrow band, frequency-stable filers and oscillators [1]. The size requirement of these antennas must be addressed, and this can be achieved by considering the used of dielectric resonators (DR). DRs fill the need for compactness, temperature-stability and high quality-factor (Q-factor) for use with microwave resonating elements. The relative permittivity of these ceramics must be high enough in order for a standing electromagnetic wave to be contained within its volume because of the potential for dielectric-air interface reflection. Titanium dioxide (TiO2) and barium titanate (BaTiO3)-based ceramics have many uses for their electrical properties, with particular applications utilizing their medium and high relative permittivities, respectively. At microwave frequencies and higher, a DR can be used in place of a resonator circuit due to its high Q-factor and minimal resistive losses. A typical DR consists of a block of ceramic material that is mounted on a printed circuit board with input and output transmission line feed networks typically in a micro-strip form [2][3]. The operating modes of a DR are determined primarily by relative permittivity and geometry. Utilizing AM one can create a monolithic part with spatially-varying permittivity which will generate different modes of operation for the DR enabling a host of new opportunities. For example, in DR filters (DRFs), this capability can be utilized to control the coupling between the micro-strip lines and the DR as well as the coupling coefficients between adjacent DRs in multi-pole filters, adding several design degrees of freedom. Similarly, in DR oscillators (DROs), this capability can be utilized to improve the coupling between the resonator and transistor circuit which will in turn improve the loaded Q-factor. In the case of a DR antenna (DRA), the graded permittivity enables one to tailor the radiation pattern of the antenna to a desired shape without changing the physical geometry of the DRA. This research considers the electrical and structural properties of the printed multi-material ceramics through the combination of rheological studies, their effects on paste-based printing, outcomes of controlling multi-material printing, and characterization of sintered parts by scanning electron microscopy and electrical impedance analysis. This system is particularly of interest due to its dielectric properties, which, when combined with the shape control offered by AM, enables the production of complex dielectric ceramic DRs.

Brandon Cox is currently a graduate student in the Materials Science & Engineering program at the Colorado School of Mines in Golden, Colorado, United States.  His research interests are in additive manufacturing of electrical ceramics, and the processing-structure-property-performance relationship that is unique to various geometries that are achievable using this technology.  Particular interest is in medium to high permittivity ceramics, as well as ferroelectric and piezoelectric ceramics.

Low-temperature Crystallization of Solution Derived Metal Oxide Thin Films - Towards the Integration of High-performance Oxides in Flexible Electronics

Invited Speaker - Maria Lourdes Calzada

ABSTRACT: To date, amorphous oxide semiconductors are considered high- performance layers that, only some few years ago, have been successfully grown on plastic substrates by low- temperature solution deposition methods.[1] More challenging is the preparation of crystalline complex oxide thin films at temperatures compatible with their direct integration in flexible plastic substrates (≤350 ºC). These metal oxides usually crystallize at temperatures over 600 ºC, which has historically excluded them from their use in flexible electronics. Significant efforts have been devoted in our group to address this challenge.[2] This presentation shows an overview to the different solution strategies that we have developed for the fabrication at low temperature of functional metal oxide films. Most of these approaches are based in the use of light as an alternative energy source to induce crystallization by photochemistry. Novel photosensitive precursors will be prepared by using different synthesis routes (modified metal alkoxides, charge-transfer metal complexes or structurally designed molecular compounds) and by a precise control over the reactions promoted by UV light (photochemical cleavage, ozonolysis, condensation or photocatalysis). The efficiency of these solution methods for the low- temperature fabrication of crystalline metal oxide films on plastic will be shown for several functional compounds like the photoferroic BiFeO3, the ferroelectric Pb(Zr,Ti)O3 or the photocatalytic β-Bi2O3.

Towards Ultra Fine Line Technology - An Industrialization Study on Photoimageable Thick Film Pastes

Invited Speaker - Jan Strueben

ABSTRACT: The trend for smaller devices in the electronics industry requires miniaturization on all levels. Especially the increased demand for sensors, 5G high frequency communication circuits, touch panel displays, smaller passive electronic components and medical devices. The degree of miniaturization has become a huge challenge for current thick film technology. The demand for finer structures has reached the limitations of screen printing which is typically used to apply thick film pastes. As a leading global supplier of materials solutions for the semiconductor and electronic packaging industries, Heraeus Electronics is well aware of the demand for component miniaturization and higher density microelectronic circuits. In this work, results from process development work done at industrial partner Neways Micro Electronics using Heraeus photoimageable pastes are presented. We show that photoimageable thick film technology can be used as robust and repeatable process in production environments. Through addition of photoactive and polymerizable components, thick film pastes are obtained that are patterned using lithographic techniques. The production of ultra fine line structures down to 25 µm are demonstrated. The factors that govern the minimum achievable linewidths are discussed. With the availability of ultra fine line thick film pastes such as conductor pastes with Ag, Au, AgPd but also dielectric pastes, the full range of materials is available to be used for hybrid manufacturing. Next to the standard requirements for thick film pastes such as printability, shelf life, firing behavior, photoimageable pastes must fulfill additional criteria. The paste must show sufficient optical properties to achieve fine line resolutions and their reliable use in a production environment. As a key property, the influence of the light penetration depth of the paste on the line resolution and the processability of the paste is being discussed. A reproducible and tolerant process is the result of proper optimization of paste composition. Paste performance and corresponding process capability is evaluated in terms of tolerance to variations in exposure and development processes. Moreover paste sintering during firing must result in predictable and reproducible behavior with respect to pattern shrinkage, line integrity as well as electrical conductivity and adhesion of the material. This is a prerequisite to set up proper design rules. Industrialization aspects are discussed, specific strengths and weaknesses compared to the standard screen printing process will be indicated. A higher level of cleanliness of working environment, tools and materials gets more important when dimensions get smaller. Under these optimal industrial conditions, capability for volume manufacturing production was demonstrated at Neways.

Advanced Detection and Manipulation of Magnetically Labeled Biomolecules using In-chip Integrated Microfluidics

Invited Speaker - Susana Cardoso de Freitas

ABSTRACT: Magnetoresistive (MR) sensors are a mature technological product with many successful applications, from industrial and automotive smart systems to precision instrumentation for biomedical areas. Irrespectively of the usage, all these applications share the need of a high spatial resolution (micrometer), room temperature operation, large scale integration and good magnetic field detectivities (ranging from mili-Tesla to pico-Tesla) at low cost. The integration of MR sensors in adaptable media (eg. flexible, stretchable substrates) offers the possibility to merge the magnetic detection capability with mechanical functionalities. On the other hand, the precision of a micrometric needle can highly benefit from the integration of MR sensors microfabricated with top-down approaches. In this work, we demonstrate through several detailed examples how advanced MR sensors (spintronic devices based on ultrathin films) can be integrated with challenging architectures – namely (i) monolithic integration with nanoelectronic ASIC, CMOS chips, (ii) flexible substrates and flexible interconnections and (iii) microfluidic technologies. Here, the challenges of handling liquids over a chip combine with those for miniaturization of microelectronics for MR readout. However, when surpassed, the result is an integrated system with added functionalities capable to answer to the request of biomedical and biochemistry for lab- on-a-chip device. A competitive feature is the reduced size, compatible with portable platforms, where sensors, electronics for control and readout and also microfluidics are packed into a single block. This solution is very attractive for biomedical applications, where lab-on-chip solutions are being provided to many applications related with the manipulation, mixing and detection of magnetic nanoparticles attached to biomolecules. As an example, portable platforms incorporating readout electronics for multiple addressing of MR sensors have been demonstrated successfully for CD4 cell counting, Salmonella detection and milk bacteria detection. However, in biochip applications where microfluidics are also integrated (so to guide the nanoparticles towards the detecting region over the MR sensors) a monolithic integration of the sensors with the CMOS wafer is not economical viable. Usually the microchannels have several 100 um, which is much larger than the MR sensor itself (few 10 um), therefore a wide area over the chip is not used by electronics, while being required for microchannel physical support. We present alternatives to the integration of MR sensor chips (low cost) with electronic readout/control available in small area CMOS chips (high cost) and very large footprint microchannels. Here we discuss alternative methods for integration of microfluidic channels using advanced chip fan-out, which has the advantages of being scalable for massive production, with high economical impact. The two technologies are brought together in a process compatible with large area wafers. In the applications above, MR sensors benefit from the maturity of microfabrication technologies over Silicon substrates (rigid), where the sensors show optimum performance when compared with flexible ones. In this work we describe some key features of magnetoresistive sensors, from the materials to the physical characteristics and technological aspects (thermal stability, noise levels, mechanical robustness upon bending). In parallel, we will describe methods for magnetic particle manipulation and trapping in a microfluidic channel, using microcoils. Here, the effectiveness of the attractive forces require large currents, combined with a smart geometry. When handling biomolecules and cells, accurate temperature control (37ºC) is crucial for cell integrity, and must be assured with additional cooling mechanisms. Strategies for in-chip cooling will be presented as well. We will present examples where these hybrid technologies are implemented towards Lab-on-chip platforms.
