Abstract

European Patent Application 0112417-A1 describes a semiconductor integrated display of the electrochromic or liquid crystal type having a semiconductor substrate with an addressable matrix of transistors integrated therein. A corresponding array of picture element (pel) display electrodes is formed over the transistor matrix after providing electrical connection vias in an intermediate insulating layer. This disclosure describes modification to the above structure to provide improved yield and performance. The basic change is to offset each driving transistor with respect to its associated electrode. The starting point of the process is as described in the above (Image Omitted) European Patent Application - a silicon substrate carrying an array of FETs with drain (D) metal contacts exposed.
