Standards for Test

摘要

Having joined the bond, assembly, test area from the 300 mm fab, I was quite surprised to discover the minimum amount of standards that serve the test area. The 300 mm ramp-up clearly benefited from extending the existing standards and the creation of a relatively full suite of both software and hardware standards. Both equipment suppliers and fabs benefited from the standards. Equipment suppliers have stated savings of 20-80% because of a reduction in the requirements from IC makers. IC makers saw a 30-50% reduction in the time to bring equipment to production. We believe that similar savings could be seen in the test area.
