Abstract : The purpose of the work performed in this contract is: To establish process improvements for the Silicon Transistor Type 2N3055 so as to attain improved operating reliability level per 1,000 hours at 25C with 90% confidence level. To incorporate two process improvements into the production facilities, and To supply engineering test samples incorporating the improved processes. During the first quarter, one group of Engineering Test Samples were shipped as per the contract requirement. The major areas of engineering activity during the report period were on the following device processing steps: geometry studies, mechanization studies, diffusion studies, wafer requirement studies, contact metallization studies, assembly studies, and device rating studies. A Program Management Chart was developed, submitted and accepted for the work planned during this contract period of eighteen months.
