How Much Data Can Be Pushed Through Copper Wires?


As the amount of digital data grows, so do requirements on the speed of the transmission at all levels of the transmission chain—between dies in a shared package, between packaged chips inside a device, and between devices. The communication channels encountered at every stage of this communication are different in nature. Those between dies in a shared package, or between packaged chips in a... » read more

Automakers Take On More Responsibility


Chip and EDA companies are scrambling to deal with stiff safety regulations and harsh environmental conditions for automotive chips, but automakers are making big changes of their own to ensure all those components work together as expected. The result is a significant shift of responsibilities of companies in the automotive supply chain. Carmakers traditionally have left verification, valid... » read more

Thinking Ahead To Society 5.0


Industry 4.0 is a familiar term throughout the global semiconductor community. It conjures images of fully automated factories and computerized decision making at all levels of business. Less widely known is Japan’s thinking about the next step in technological evolution, which it calls Society 5.0. Instead of viewing upcoming technology advances as the fourth industrial revolution, Japan tak... » read more

Improving In-System Test With Tessent VersaPoint Test Point Technology


This paper describes a new versatile test point technology called VersaPoint, which has been developed specifically to work with designs implementing mixed EDT/LBIST methodologies to reduce EDT pattern counts and improve Logic BIST (LBIST) test coverage. VersaPoint test points can reduce compressed pattern counts 2X to 4X beyond compression alone and improve LBIST test coverage beyond what is p... » read more

Advanced Defect Inspection Techniques For nFET And pFET Defectivity At 7nm Gate Poly Removal Process


By Ian Tolle, GlobalFoundries, and Michael Daino, KLA-Tencor During 7nm gate poly removal process, polysilicon is removed exposing both NFET and PFET fins in preparation for high-k gate oxide. If the polysilicon etch is too aggressive or the source and drain are not sufficiently protected, the etch can damage the active region and render the FET inoperative. Different materials are used in t... » read more

Auto Chip Design, Test Changes Ahead


The automotive industry’s unceasing demand for performance, coupled with larger and more complex processors, are driving broad changes in how electronics are designed, verified and tested. What's changing is that these systems, which include AI-oriented logic developed at the most advanced process nodes, need to last several times longer than traditional IT and consumer devices, and they n... » read more

System-Level Test: Where Does It Fit?


Our second C-Brief discusses where system-level test (SLT) best fits into your semiconductor test workflow. With automated testing equipment (ATE), a traditional workflow may consist of: Wafer sort (WS) Burn-in after packaging (BI) Combination of structural testing (ST) and functional testing (FT). As demands on high-volume manufacturing shift in response to wider industry and com... » read more

Intel Buys NetSpeed for NoC, Fabric IP


Intel acquired NetSpeed Systems, taking in network-on-a-chip and interconnect fabric intellectual property for designing, developing, and testing system-on-a-chip devices. The acquisition gives Intel a key missing ingredient in its plan to develop customized heterogeneous solutions for its customers. The company now has various memory pieces, interconnect bridges, programmable logic and ASIC... » read more

The Quest For Perfection


Demands by automakers for zero defects over 15 years are absurd, particularly when it comes to 10/7nm AI systems that will be the brains of autonomous and assisted driving or any mobile electronic device. There are several reasons for this. To begin with, no one has ever used a 10/7nm device under extreme conditions for any length of time. Chips developed at these nodes are just starting to ... » read more

5G Lessons Learned From Automotive Radar Test


Situated between microwave and infrared waves, the millimeter-wave spectrum is the band of spectrum between 30 gigahertz (GHz) and 300GHz. It is used for high-speed wireless communications and is widely considered as the means to bring 5G into the future by allocating more bandwidth to deliver faster, higher-quality video, and multimedia content and services. Automotive radar is the entry point... » read more
