Abstract

A strong correlation has been found between the electrical, compositional and structural properties of the polysilicon contact and its interface with the heavily doped pol isi 1-emitter of a transistor. The integrity and thickness of the oxide interface is a major factor for improving the observed performance. Transistors for which the polysilicon was also the diffusion source for the emitter were studied.
