The purpose of this program is to improve the reliability of the C600 series field effect transistors by specific improvements of manufacturing techniques. The basic program has been outlined in a PERT plan which is being used as a reference. In an effort to achieve the failure rate objective, the following improvements were incorporated into the production process 1 Oxidation of slices 2 Boron diffusion of slices 3 Mask alignment 4 Etching of slices 5 Die-to-header bonding 6 Wire bonding and 7 Packaging.
