Artificial intelligence Renesas develops chip to detect production problems

TOKYO — Renesas Electronics has created chips with artificial intelligence that can predict malfunctions in manufacturing equipment, helping to prevent breakdowns and product defects.      The chipmaker worked with XCompass Intelligence, an AI research startup founded at the Tokyo Institute of Technology, on development. The chips examine such data as sounds, equipment warping, temperature, and voltage changes for signs that equipment is about to malfunction. The AI can learn automatically, improving its accuracy.      When the chips were installed experimentally at Renesas’ Naka facility in Ibaraki Prefecture, they spotted problems based on concentrations of a certain gas in chipmaking equipment. Testing of several thousand of the silicon wafers used to make semiconductors showed a sixfold improvement over the old system in accurately detecting equipment problems causing defects, Renesas said.      Accurate detection of…
