MARTIN MARIETTA HAS AI WAFER TESTING PROGRAMME

Martin Marietta Corp’s Baltimore, Maryland research laboratory has come up with an artificial intelligence program to test wafers of high-frequency integrated circuits 20 times faster than current methods: test probes at various points on a wafer examine data from all the circuits and if performance is down in one area, a computer directs a more thorough examination of that area, so that the bad circuit be can isolated rather than scrap the entire wafer; the testing technique will be used in Marietta’s Microwave/Millimeter Wave Monolithic Integrated Circuits Gallium Arsenide joint venture with ITT Corp.
