Real-Time Safety Monitoring


Various types of semiconductor test will determine whether a chip is free of defects and meets the specification, but understanding how it's behaving in the field under real workloads and harsh ambient conditions may be very different in automotive applications, where vibration, heat, cold can disrupt the normal functioning of a chip over time and reduce its lifespan. Alex Burlak, vice presiden... » read more

Functional Compaction for Functional Test Sequences (Purdue University, I. Pomeranz)


A new technical paper titled "Functional Compaction for Functional Test Sequences" was published by IEEE Fellow Irith Pomeranz at Purdue University. Abstract: "The occurrence of silent data corruption because of hardware defects in large scale data centers points to the advantages of applying functional test sequences to detect hardware defects that escape scan-based tests. When using funct... » read more

Cost And Quality Of Chiplets


Chiplets add a whole new challenge for the semiconductor industry. How much testing is enough? How do you optimize system binning? What’s the right amount of burn-in? The answers to these questions will vary, depending upon cost and quality tradeoffs, the number and source of the chiplets, and real-world workloads and projected lifespans. Marc Jacobs, senior director of solutions architectur... » read more

AI/ML Challenges In Test and Metrology


The integration of artificial intelligence and machine learning (AI/ML) into semiconductor test and metrology is redefining the landscape for chip fabrication, which will be essential at advanced nodes and in increasingly dense advanced packages.
