IC Equipment Communication Standards Struggle As Data Volumes Grow
By Anne Meixner - 11 Feb, 2025 - Comments: 0

The tsunami of data produced during wafer fabrication cannot be effectively leveraged without standards. They determine how data is accessed from equipment, which users need data access and when, and how fast it can be delivered. On top of that, best practices in data governance and data quality are needed to effectively interpret collected data and transfer results. When fab automation and ... » read more

Using AI In Semiconductor Inspection
By Ed Sperling - 05 Feb, 2025 - Comments: 0

AI is exceptionally good at spotting anomalies in semiconductor inspection. The challenge is training different models for different inspection tools and topographies, and knowing which model to use at any particular time. Different textures in backgrounds are difficult for traditional algorithms, for example. But once machine learning models are trained properly, they have proven effective in ... » read more

AI In Data Management Has Limits
By Adam Kovac - 03 Feb, 2025 - Comments: 0

AI algorithms are being integrated into a growing number of EDA tools to automate different aspects of data management, but they also are forcing discussions about just how much decision-making should be turned over to machines and when that should happen. The ability of AI to sort through enormous amounts of design data to find patterns, both good and bad, is well recognized at this point. ... » read more

AI Won’t Replace Subject Matter Experts
By Adam Kovac - 15 Jan, 2025 - Comments: 0

Experts at The Table: The emergence of LLMs and other forms of AI has sent ripples through a number of industries, raising fears that many jobs could be on the chopping block, to be replaced by automation. Whether that’s the case in semiconductors, where machine learning has become an integral part of the design process, remains to be seen. Semiconductor Engineering sat down with a panel of e... » read more
