AMORPHOUS SILICON M I S DEVICE

摘要

The present invention relates to an amorphous silicon MIS device having an insulating oxide formed by the chemical oxidation of the silicon surface. A process comprising etching the silicon surface followed by a treatment of the etched surface in a sulfur based oxidant forms a controlled thickness oxide layer, useful in modifying the junction forming characteristics of the semiconductor and additionally stabilizing the semiconductor properties of the photoconductive amorphous silicon.
