PHOTOSENSITIVE GAS PHASE ETCHING OF SEMICONDUCTORS BY SELECTIVE RADIATION

Patent ·
OSTI ID:4685599

A method for fabricating diffused semiconductor devices and for shaping a resistant overlayer for controlling a subsequent diffusion of significant impurities into a semiconductor substrate is presented. The method is based on the fact that IF/sub 5/ is particularly sensitive to appropriate radiation in the form of F/sub 2/O. Examples of the technique are described. (P.C.H.)
