Abstract

PURPOSE: A thickness difference of oxidization film is made at least between the electrical contact are a within diffusion region and the substrate outside diffusion region, so that the latter is made thicker than the former. In this way, the diffusion region pattern can be simplified as well as contact hole opening conditions for oxidization film can be relieved.
