Micross Components Details Proprietary Tester to Detect Counterfeit Semiconductors at electronica 2012
Micross Components, a leading global provider of specialty electronic components, will be discussing their proprietary ConTest-1K™ tester at electronica 2012. This equipment provides a means to quickly evaluate internal pin connections for continuity and conformance to known good components.
"Micross has always supported vigilance against counterfeit components," notes Jamie Knight, General Manager of Micross UK. "Our policy is to purchase components from only direct and authorized sources. We follow strict inspection procedures and offer a full portfolio of visual, electrical, and mechanical evaluation capabilities. Detecting counterfeit components is not always straightforward, and our heritage allows us to make expert judgment calls."
Recent US legislation requires contractors to bear the costs of surveillance, detection, and replacement of counterfeit components. This makes it all the more critical that contractors team with proficient and conscientious suppliers who will be their front-end sentinels against counterfeit devices.
With the ConTest-1K™ tester, a detailed VI curve trace is performed on each pin and is compared either against a reference device if it exists, or against other devices in the batch. The VI curves are also manually analyzed to verify against expected results. Programming takes less than 5 minutes and a full 1024-pin sweep less than 3 seconds.
Atotech’s CupraEtch™ DE – The new and “green” differential etch process for SAP manufacturing
One of the key manufacturing processes for enabling the construction of IC-substrates with semi-additive processes (SAP) and modified semi-additive processes (MSAP) is the so-called differential etch process. It leads to different etch rates on electroless and electroplated copper and is used for the circuitization of copper tracks in the IC-packaging industry. Atotech’s new product, Cupra Etch™ DE, is based on iron sulfate etch. In this way, it differentiates itself from all known differential etch processes in the industry, which are based on sulfuric acid and hydrogen peroxide.
CupraEtch™ DE‘s iron sulfate etch runs in parallel with a regeneration unit. Offering a unique ferric sulfate system, it effectively removes the seed layer of electroless copper. Meanwhile, the regeneration unit plates out the copper for recycling use. This leads to an elimination of undercuts, a reduced amount of waste water and thereby to reduced costs of ownership.
Advantages of CupraEtch™ DE
CupraEtch™ DE has many advantages over commonly used differential etch processes. The main advantages are:
It’s superb etching capability effectively removes electroless copper seeds, while minimizing the occurrence of track undercuts
It retains the contour of the finest conductors without undercuts at the foot
The undercut-free circuitry enhances the reliability of IC-substrates
“This green differential etch process is environmentally friendlier than the commonly used differential etch process,” states Dr. Rami Haidar, Global Product Manager for Surface Treatment Technology at Atotech Deutschland GmbH in Berlin, Germany. “Its regeneration unit, which plates out the etched copper and regenerates the ferric component in the chemistry, reduces the amount of waste water generated from the differential etch process. This also leads to reduced costs of ownership.”
The differential etch process with CupraEtch™ DE
CupraEtch™ DE eliminates the draw-backs associated with the typical peroxide based etchants, such as:
No feed and bleed operation is needed. Instead, it offers the possibility to regenerate solutions in bypass equipment. A considerable amount of chemical waste and the need for high waste treatment is therewith eliminated.
CupraEtch™ DE does not etch three-dimensionally. Peroxide etchants etch three-dimensionally, causing undercuts of conductor tracks of several micrometers and affecting the mechanical stability of the track and its electrical properties.
Figure 1 and 2 show a comparison between cross section pictures of tracks after the differential etch process. In Figure 1, tracks were treated with a differential etch process based on sulfuric peroxide. Undercuts are clearly visible. Figure 2, however, does not show any undercuts on the conductor side walls: It has been treated with CupraEtch™ DE, the differential etch finisher. Electronics

STATS ChipPAC’s Advanced eWLB Provides a Versatile Integration Platform for the 2.5D and 3D Technology Evolution
STATS ChipPAC announced expanded packaging options for advanced embedded Wafer Level Ball Grid Array (eWLB) technology that provide a versatile platform for the semiconductor industry’s technology evolution from single or multi-die 2D package designs to 2.5D interposers and 3D System-in-Package (SiP) configurations.
The advancement of silicon scaling to 14nm in support of higher performance, higher bandwidth and lower power consumption in portable and mobile devices is pushing the boundaries of emerging packaging technologies to smaller fan-out packaging designs with finer line/spacing as well as improved electrical performance and passive embedded technology capabilities.
Interposers are used to connect one active die to another in a 2.5D package configuration, enabling very dense interconnection with more effective heat dissipation, improved processing speed and the flexibility to integrate die from different manufacturing sources. While STATS ChipPAC continues to be in the forefront of the development and commercialization of Through Silicon Via (TSV) as a 2.5D and 3D integration technology, the Company has in parallel developed new eWLB based interposers to support high density interconnection and routing of multiple dies in a proven, low-warpage packaging structure.
With the inherent performance and cost advantages of eWLB, STATS ChipPAC is also effectively addressing some of the challenges in high end flip chip applications that require much finer bump pitches, higher I/O densities and the elimination of stress on extreme low-k or ultra low-k (ELK/ULK) dielectric structures at advanced silicon wafer nodes. eWLB’s fan-out packaging approach with its inherently lower stress, larger pad pitch, fine line width/spacing and redistribution layer (RDL) allows higher integration and routing density in less metal layers in an fcBGA substrate.
STATS ChipPAC also offers eWLB PoP solutions in either a single or double-sided configuration which provide a flexible integration platform for stacking a wide range of memory packages on top with a final stacked package height below 1.0mm. The number of interconnections between memory and processor can be up to 1024. The double-sided eWLB PoP technology features a flexible redistribution layer that can accommodate multiple active or passive devices in complex 3D SiP structures which enable very thin profiles, increased performance and superior warpage control.
Torrey Hills Honored for Innovative Mine-Safety Technology
Company to transfer game-changing tools and processes from R&D to commercialization phase for mine safety and greenhouse gas reduction
Torrey Hills Technologies, LLC has been named a finalist in the 2012 World Technology Awards competition for its innovative methane-gas-capturing process to dramatically improve safety in underground coal mines. The prestigious World Technology Network (WTN) awards, presented in association with TIME, Fortune, CNN, Science/AAAS, Technology Review and others, have been called “the Oscars of the technology world.”
Corporations and individuals in 20 categories are nominated by their peers for the annual awards. Along with Torrey Hills, Siemens and Qualcomm CEO Paul E. Jacobs were among this year’s finalists. Other nominees included Apple, Google, IBM and AT&T.
As a finalist in the Energy category, Torrey Hills automatically gains membership in the WTN-- a global community of individuals and corporations who are exploring what is imminent, possible and of lasting significance in emerging technologies. “This is a great honor for a small company like ours. It also speaks volumes about our lifesaving invention, which addresses the devastating problem of exploding methane gas in underground coal mines and on oil rigs,” said Ken Kuang, founder and president of Torrey Hills Technologies.
On an annual basis, methane gas explosions claim the lives of thousands of miners and generate an estimated $45 billion in economic losses worldwide. Torrey Hills is developing novel methane capture and recovery techniques to supplement ventilation, which is the only established and proven technology for alleviating methane problems. Since modern coal mines have complicated underground networks, it is virtually impossible to ventilate every corner equally.
By developing inventive and affordable methane-capturing products and processes, Torrey Hills is targeting three critical global issues: preventing and mitigating gas explosions, capturing greenhouse emissions that damage the environment, and converting methane gas into liquid methanol, which is a clean fuel and a useful chemical raw material. The company has received two rounds of R&D funding from the National Science Foundation and is seeking investors for the commercialization phase.
Founded in 2004, Torrey Hills has appeared on the list of INC Magazine’s Fastest Growing Private Companies for the past three years. The company, which maintains its headquarters in San Diego and a manufacturing facility in Yixing, China, supplies electronic components and heavy equipment to the electronics and alternative energy industries.
