Abstract:
A method for fabricating a semiconductor device, comprising the steps of:a) forming a first semiconductor body;b) forming a laminated structure of an insulating layer on said first semiconductor body and a conductive layer on said insulating layer;c) forming insulating spacers on sidewalls of said laminated structure, each of said spacers having a width W; andd) forming a diffusion layer in said first semiconductor body so that an edge of said diffusion layer is adjacent to one of said spacers;e) forming a second semiconductor body; andf) forming a shared contact hole in said second semiconductor body for establishing an ohmic contact between said diffusion layer and said conductive layer, a center axis of the shared contact hole being located a distance W/2 from an edge of said laminated structure--so that portions of said diffusion layer and said conductive layer which are exposed to the outside through said shared contact hole have substantially equal areas.
