IC Test And Quality Requirements Drive New Collaboration


Rapidly increasing chip and package complexity, coupled with an incessant demand for more reliability, has triggered a frenzy of alliances and working relationships that are starting to redefine how chips are tested and monitored. At the core of this shift is a growing recognition that no company can do everything, and that to work together will require much tighter integration of flows, met... » read more

DRAM Test And Inspection Just Gets Tougher


DRAM manufacturers continue to demand cost-effective solutions for screening and process improvement amid growing concerns over defects and process variability, but meeting that demand is becoming much more difficult with the rollout of faster interfaces and multi-chip packages. DRAM plays a key role in a wide variety of electronic devices, from phones and PCs to ECUs in cars and servers ins... » read more

High Voltage Testing Races Ahead


Voltage requirements are increasing, especially for the EV market. Even devices that might be considered relatively low voltage, such as display drivers, are now pushing past established baselines. While working with high voltages is nothing new — many engineers can recall yellow caution tape in their workplaces — the sheer number and variety of new requirements have made testing at high... » read more

More Manufacturing Issues, More Testing


Douglas Lefever, CEO of Advantest America, sat down with Semiconductor Engineering to talk about changes in test, the impact of advanced packaging, and business changes that are happening across the flow. What follows are excerpts of that discussion. SE: What are the big changes ahead in test? Lefever: It's less about inflection points and more like moving from algebra to calculus in the ... » read more

Using Analytics To Reduce Burn-in


Silicon providers are using adaptive test flows to reduce burn-in costs, one of the many approaches aimed at stemming cost increases at advanced nodes and in advanced packages. No one likes it when their cell phone fails within the first month of ownership. But the problems are much more pressing when the key components in data warehouse servers or automobiles fail. Reliability expectations ... » read more

Adaptive Test Gains Ground


Not all devices get tested the same way anymore, and that’s a good thing. Quality, test costs, and yield have motivated product engineers to adopt test processes that fall under the umbrella of adaptive test, which uses test data to modify a subsequent test process. But to execute such techniques requires logistics that support analysis of data, as well as enabling changes to a test based ... » read more

Using ML In Manufacturing


How to prevent early life failures by applying machine learning to different use cases, and how to interpret models for different tradeoffs on reliability. Jeff David, vice president of AI solutions at PDF Solutions, digs down into how to utilize data to improve reliability. » read more

Using Static Analysis For Functional Safety


Fadi Maamari, group director for R&D at Synopsys, explains why static analysis is suddenly in demand in auto chip design, how it can help to choose the best implementation of functional safety approaches, and where it fits into the design flow. » 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

2017 ITC Wrap-up


Advantest was among the exhibitors and corporate sponsors at last week’s 2017 International Test Conference in Fort Worth, Texas. The automatic test equipment company also presented papers, took part in sessions, and provided posters during ITC’s technical program. In the booth, Advantest demonstrated its on-demand CloudTesting Service. It also showed off its EVA100 analog/mixed-signal IC t... » read more
