Abstract : The report deals with the research and development conducted during the investigation of localized defects and hot spots in high voltage p-n-p-n inverter switches. The effects of gallium and phosphorus layers upon the diffusion of gold in silicon are reported. In particular, the distribution of gold in Device 'D' is illustrated. In connection with the Device 'D' failure study, work was performed in relation to (1) the effects of the emitter short patterns, (2) the size and distribution of hot spots, (3) the device photoresponse in the vicinity of a hot spot, and (4) thermal transient measurements at a hot spot.
