Cost And Quality Of Chiplets
By Ed Sperling - 19 Mar, 2024 - Comments: 0

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
By Gregory Haley - 12 Mar, 2024 - Comments: 0

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. Fabs today are inundated by vast amounts of data collected across multiple manufacturing processes, and AI/ML solutions are viewed as essential for... » read more

Adaptive Test Ramps For Data Intelligence Era
By Laura Peters - 08 Feb, 2024 - Comments: 0

Widely available and nearly unlimited compute resources, coupled with the availability of sophisticated algorithms, are opening the door to adaptive testing. But the speed at which this testing approach is adopted will continue to vary due to persistent concerns about data sharing and the potential for IP theft and data leakage. Adaptive testing is all about making timely changes to a test p... » read more

Unlocking Value: The Power of AI in Semiconductor Test
By Advantest - 09 Jan, 2024 - Comments: 0

AI (Artificial Intelligence) and data analytics empower semiconductor manufacturers to extract valuable insights from the massive amounts of data generated throughout the silicon lifecycle. By leveraging AI algorithms, semiconductor manufacturers can optimize silicon design, assembly, and testing processes. Through the analysis of vast datasets, AI can identify patterns, predict failures, and o... » read more

Integration Challenges For ATE Data
By Gregory Haley - 10 Oct, 2023 - Comments: 0

Tighter integration of automatic test equipment (ATE) into semiconductor manufacturing, so that data from one process can be seamlessly leveraged by another, holds significant promise to boost manufacturing efficiency and yield. The challenge is selling this concept to fabs, packaging houses, and their customers. Data involving yield parameters, process variations, and intricate details abou... » read more

Challenges Of Testing Advanced Packages
By Ed Sperling - 19 Sep, 2023 - Comments: 0

The number of things that can wrong in assembly and test increases as more chips are added into a package. Testing is the usual guarantor of a reliable device, but in an advanced package there are all sorts of new issues — more contacts, different handling requirements, the necessary thermal conditions for test, and variation within the package. George Harris, vice president of global test se... » read more

Fab And Field Data Transforming Manufacturing Processes
By Gregory Haley - 12 Sep, 2023 - Comments: 0

The ability to capture, process, and analyze data in the field is transforming semiconductor metrology and testing, providing invaluable insight into a product's performance in real-time and under real-world conditions and use cases. Historically, data that encapsulates parameters such as power consumption, temperature, voltages, currents, timing, and other characteristics, was confined to d... » read more

Customizing IC Test To Improve Yield And Reliability
By Ed Sperling - 12 Sep, 2023 - Comments: 0

Testing the performance and power of semiconductors as they come off the production line is beginning to shift left in the fab, reversing a long-standing trend of assessing chips just prior to shipping. While this may sound straightforward, it's a difficult challenge which, if successful, will have broad implications for the entire design-through-manufacturing flow. Manufacturers typically g... » read more

Adding Security Into Test
By Ed Sperling - 04 Apr, 2023 - Comments: 0

Security is becoming a much bigger concern as more electronics are added into cars, as more devices are connected to the internet, and as the value of data continues to increase. The problem is that security is dynamic. It continues to change throughout the lifetime of a system, and some of these devices are expected to last for a decade or more. Lee Harrison, director of Tessent product market... » read more

Test Connections Clean Up With Real-Time Maintenance
By Anne Meixner - 08 Nov, 2022 - Comments: 0

Test facilities are beginning to implement real-time maintenance, rather than scheduled maintenance, to reduce manufacturing costs and boost product yield. Adaptive cleaning of probe needles and test sockets can extend equipment lifetimes and reduce yield excursions. The same is true for load board repair, which is moving toward predictive maintenance. But this change is much more complicate... » read more
