ABSTRACT:
A method for fabricating a semiconductor device is disclosed which includes a step of forming contact holes in insulating films on a substrate, forming a silicate glass layer containing an impurity over the entire surface, and performing the phosphorus getter treatment using POCl.sub.3 at a high temperature. Even when the phosphorus getter treatment is performed after the formation of the contact holes, the substrate or electrodes exposed through the contact holes may not be reduced in thickness or damaged. The impurity may be diffused into the substrate from the silicate glass layer through the contact holes.
