Course Descriptions

A1: 
Polymers For Wafer Level Packaging
Jeffrey Gotro, InnoCentrix, LLC

The course will provide an overview of polymers used in wafer level packaging and the important structure-property-process-performance relationships for polymers used in wafer level packaging.  The main learning objectives will be: 1) gain insights on how polymers are used in Fan Out Wafer Level Packaging, specifically mold compounds and polymer redistribution layers (RDL) 2) learn the key polymer and processes challenges in Fan Out Wafer Level Packaging including panel level processing, and 3) understand the types of polymers used in wafer level packages, including pre-applied and wafer applied underfills. We will cover in more depth the chemistries, material properties, process considerations for polymers used in wafer level packaging.  The course has been completely updated to include a detailed discussion of the polymers and polymer-related processing for Fan-Out Wafer Level packaging (such as chip first and chip last process flows).

B1: 
Sensor Packaging
Robert Dean, Auburn University

Without modern electronic packaging technologies, many useful or even necessary sensors would not be able to be commercialized.  Packaging is an integral part of modern sensor technology and can account for as much as half of the cost of manufacturing a packaged sensor.  This PDC will convey the current state-of-the-art in packaging of sensors, and will primarily focus on the packaging of solid state chip sensors.  After an overview of current chip sensor technologies, I will discuss the unique characteristics and requirements for successfully packaging these types of sensors so that they possess the necessary access to the operating environment required for successful functioning, as well as the indispensable protection from the operating environment needed to achieve long term reliable operation.  Relevant sensor technologies will be discussed, such as MEMS inertial sensors (accelerometers, vibratory gyroscopes, and single-chip IMUs), MEMS pressure sensors, chemical sensor chips (relative humidity, moisture content, pH, electrical conductivity, conductimetric, etc.), temperature sensors, optical sensors, and more.  Each of these types of chip sensors possesses distinct packaging requirements, as well as unique vulnerabilities.  For example, MEMS inertial sensors are often hermetically packaged to isolate them from moisture, mechanical contact, dust, and exposure to harsh chemicals possibly present in their operating environment.  However, because they consist of microfabricated structures, these sensors may be sensitive to high frequency and/or high energy mechanical vibrations or acoustic signals that could be present in the intended operating environment.  If certain frequency components of these environmentally present signals couple through the hermetic package to the chip sensor, they could adversely affect the operation of the sensor by resonating the sensor's microstructures.  So, additional packaging structures may be required, beyond just hermetically sealing the sensor dice inside a package, to attenuate undesirable vibration or acoustic components.  Furthermore, in order to achieve sufficiently long operational lifetimes, the hermetic package may require a getter in order to maintain a desired pressure or gas chemistry inside the package for optimal sensor performance.  Another example is chemical chip sensors, which although they might be impervious to high frequency environmental vibrations or acoustic excitation, they may be very sensitive to dust accumulation or condensation on the active surface of the chip sensor, requiring this issue to be mitigated by the sensor package.  Similarly, optical sensors may require a transparent window in the package or package lid to be free of dust accumulation for optimal sensor performance.  Sensor packaging also affects other potentially important issues related to modern applications for chip sensors, such as the co-packaging of sensor and electronics chips, energy harvesting from the ambient environment to power the sensor, wireless data transfer to or from the sensor, sensors for biomedical applications, flexible sensors, and the roll of additive manufacturing related to sensor packaging.  These topics will also be covered in this PDC.

A2: 
Fan Out Variations - Structures and Processes for Low and High Density 
John Hunt, ASE Group

Fan Out technology has evolved as an alternative package to meet the need for miniaturization of electronics, while also providing improved electrical interconnectivity.  Until around 2016, Fan Out was considered primarily a solution for low density packaging requirements.

The wide use of mobile and many IOT devices coming into use has driven the need for increased capability of data centers.  Fan Out technology is now in production for many of these applications.  It also enables the heterogeneous integration of die and memory with improved electrical performance and lower cost than traditional 2.5 packaging for these data center requirements. With the advent of chiplet packaging, fan out also offers a cost-effective solution for this combination of multiple die in a single package.

We will review how the integration of wafer level processing technologies and Flip Chip packaging structures have come together into recent advances in both low density and high-density Fan Out packaging. These packages are for automotive, IoT, advanced mobile and server applications. They can have higher levels of integration and sophistication than has ever been possible in the past.  A brief overview of the concept of Fan Out packaging and history of its evolution, and Fan Out developments to meet both low- and high-end applications will be included in this course.

B2:
Flexible Hybrid Electronics 2.0 
Subramanian Iyer, UCLA

Flexible Hybrid Electronics (FHE) has made a significant impact in medical electronics and wellness devices using the methods of classical packaging.

This tutorial will address the application space, material aspects, integration technology, energy storage and management as well as the semiconductor ecosystem needed to to take FHE to the next level. We will relate this to what is happening in the heterogeneous integration area and show how the dielet / chiplet revolution can have significant impact on FHE as well.        

A3: 
The Evolution of Flip Chip Package Technology
Mark Gerber, ASE Group

This PDC course will provide a historical overview and background on the evolution of flip chip packaging as well as short market perspective on this platform. Mobile, Infrastructure, Automotive, High Reliability, Medical and High-Performance Network and Computing all rely on Flip Chip technology to enable their silicon solutions.  Although the use of new technologies such as Fan-Out hold promise for certain applications, flip chip advancements continue to challenge many new technology competitors from a price and reliability perspective and may end up driving hybrid approaches.  Interconnect structure, process flows, materials and package integration process methods for evolving Flip Chip applications will be discussed in detail. Understanding the trade-offs between the different bump structures and package platforms is key in determining the silicon device layout and the type of design rules that can be leveraged for new products. As part of this course, the assembly process details will be discussed and will include Mass Reflow, Thermo-Compression Non-Conductive Paste (TCNCP) bonding and Laser Assisted Bonding. Reliability aspects such as IMC formations and ways to address will also be covered as a key consideration for Interconnect decisions.      

B3:
3D Package Assembly and Technology for Mobile Devices
