Hunting For Open Defects In Advanced Packages


Catching all defects in chip packaging is becoming more difficult, requiring a mix of electrical tests, metrology screening, and various types of inspection. And the more critical the application for these chips, the greater the effort and the cost. Latent open defects continue to be the bane of test, quality, and reliability engineering. Open defects in packages occur at the chip-to-substra... » read more

Week In Review: Manufacturing, Test


Government policy For the last four years, the U.S. and China have been embroiled in a trade war, especially on the technology front. The U.S. has implemented a number of export control measures and tariffs in the arena. But there might be a thawing in the tense relationship between the two superpowers. “Reports surfaced Thursday indicating the China Semiconductor Industry Association (CSIA)... » read more

Making Sure AI/ML Works In Test Systems


Artificial intelligence/machine learning is being utilized increasingly to find patterns and outlier data in chip manufacturing and test, improving the overall yield and reliability of end devices. But there are too many variables and unknowns to reliably predict how a chip will behave in the field using just AI. Today, every AI use case — whether a self-driving car or an industrial sortin... » read more

Part Average Tests For Auto ICs Not Good Enough


Part Average Testing (PAT) has long been used in automotive. For some semiconductor technologies it remains viable, while for others it is no longer good enough. Automakers are bracing for chips developed at advanced process nodes with much trepidation. Tight control of their supply chains and a reliance upon mature electronic processes so far have enabled them to increase electronic compone... » read more

Week In Review: Manufacturing, Test


Chipmakers and OEMs A severe winter storm has hit many parts of the United States, including Texas. In Austin, utility providers are prioritizing service to residential areas. As a result, electricity and natural gas providers have temporarily suspended service to Austin’s semiconductor manufacturers, including Samsung and NXP. "Due to the recent blackouts in Texas, Samsung Austin Semicon... » read more

Automotive Test Moves In-System


With the electrification of automobiles, it’s not enough to test the new electronics thoroughly at the end of the manufacturing process. Safety standards now require that tests be performed live, in the field, with contingency plans should a test fail. “We see clear demand from the automotive semiconductor supply chain for design functionality specifically aimed at in-system monitoring,�... » read more

New Transistor Structures At 3nm/2nm


Several foundries continue to develop new processes based on next-generation gate-all-around transistors, including more advanced high-mobility versions, but bringing these technologies into production is going to be difficult and expensive. Intel, Samsung, TSMC and others are laying the groundwork for the transition from today’s finFET transistors to new gate-all-around field-effect trans... » read more

Week In Review: Manufacturing, Test


Market research For some time, China has faced an enormous trade gap in semiconductors. In response, China has been developing its semiconductor industry with plans to make more of its chips. But China is expected to fall far short of its “Made in China 2025” goals for IC production, according to IC Insights. “IC Insights forecasts China-produced ICs will represent only 19.4% of its I... » read more

Week In Review: Manufacturing, Test


Chipmakers and OEMs Third Point, a hedge fund, released a letter, saying that Intel needs to explore its strategic alternatives. This includes the breakup of the chip giant. Obtained by Yahoo and others, the letter says Intel needs to decide “whether Intel should remain an integrated device manufacturer” and should divest certain failed acquisitions. Here’s another analysis of the sit... » read more

Variation Threat In Advanced Nodes, Packages Grows


Variation is becoming a much bigger and more complex problem for chipmakers as they push to the next process nodes or into increasingly dense advanced packages, raising concerns about the functionality and reliability of individual devices, and even entire systems. In the past, almost all concerns about variation focused on the manufacturing process. What printed on a piece of silicon didn't... » read more
