摘要： Herein disclosed is a semiconductor integrated circuit device fabricating process for forming MISFETs over the principal surface in active regions of a substrate, which are surrounded by inactive regions formed of an element separating insulating film and channel stopper regions. The disclosed process includes forming insulating films over wiring lines including uppermost wiring lines, the uppermost wiring lines having gaps between adjacent uppermost wiring lines. The insulating films include forming a silicon oxide film over the wiring lines and in the gaps between adjacent uppermost wiring lines, and forming a silicon nitride film over the silicon oxide film, the silicon nitride film being formed by plasma chemical vapor deposition. The silicon oxide film is formed to have a thickness of at least one-half of the gap between adjacent uppermost wiring lines, with the silicon nitride film being thicker than the silicon oxide film.

摘要： Herein disclosed is a semiconductor integrated circuit device fabricating process for forming MISFETs over the principal surface in those active regions of a substrate, which are surrounded by inactive regions formed of an element separating insulating film and channel stopper regions, comprising: the step of for forming a first mask by a non-oxidizable mask and an etching mask sequentially over the principal surface of the active regions of the substrate; the step of forming a second mask on and in self-alignment with the side walls of the first mask by a non-oxidizable mask thinner than the non-oxidizable mask of the first mask and an etching mask respectively; the step of etching the principal surface of the inactive regions of the substrate by using the first mask and the second mask; the step of forming the element separating insulating film over the principal surface of the inactive regions of the substrate by an oxidization using the first mask and the second mask; and the step of forming the channel stopper regions over the principal surface portions below the element separating insulating film of the substrate by introducing an impurity into all the surface portions including the active regions and the inactive regions of the substrate after the first mask and the second mask have been removed.

摘要： The present invention relates to a method for filling small via holes provided to insulating film on a wafer to expose parts of the underlayer of the wafer by metal by means of CVD, and an apparatus therefor. The gist of the present invention lies in that, before CVD is conducted, a surface cleaning treatment of small via hole bottom underlayer surface and a stabilization treatment of insulating film surface activated thereby are carried out successively or simultaneously and optionally an anti-corrosive treatment is applied to underlayer surface, and then the CVD treatment is conducted without exposing the underlayer metal subjected to above treatments to the air. The present invention provides an effect of enabling via filling by metal which shows good selectivity and gives a low interfacial resistance between underlayer metal and filled metal.
