Abstract:

Silicon material was received, evaluated and processed through the initial phases of device fabrication. Material evaluation indicates that the silicon approximates the required specifications. Sample fabrication was initiated about one of the device structures. Diffusion results and evaluations are given. A modified capsule design for anticipated improved thermal characteristic is discussed. Design features of both approaches are given. Test fixtures are discussed in view of the extended current rating 500A compared to conventional devices.
