Title: Integrated circuit prodn. with FET in silicon substrate - with polycrystalline silicon gate electrode and planar insulating oxide film
Inventor: TOUCHY WOLFGANG DIPL PHYS DR
IPC: H01L21/321
Filed: 1975-12-03
Abstract: Oxidising part of the substrate to form an insulating SiO2 film involves forming the insulating film in such a way that a planar surface is obtd. using the oxide grown in both directions. Pref. the insulating layer is formed directly on the substrate or by partial oxidn. of a polycrystalline Si film. The process utilises the fact that SiO2 forms in an O2 atmos. half by diffusion of O2 into the SiO2, already formed and by expansion in vol. A new surface results which is half the thickness of the insulating oxide film higher than the original surface. By removal of this oxide film and reoxidn. the surface can be made level with the original plane or even lower, so that sharp edges are avoided. This procedure can be used with both monocrystalline and polycrystalline Si. The claims cover the prodn. of the insulating film using suitable masks and also doping by diffusion or ion implantation.
