<p>A process for producing a semiconductor device comprises a step of polishing of a region of an electroconductive material serving as an electrode or a wiring line in an insulating layer formed on a semiconductor region, the region of the electroconductive material being electrically connected to the semiconductor region, wherein a region of another material is formed within the region of the electroconductive material to be polished. Also a semiconductor device having the region is provided. A process for producing an active matrix substrate comprises a step of polishing of picture element electrodes made of a metal provided on crossing portions of plural signal lines and plural scanning lines and a means for applying voltage to the picture elements, wherein a region of another material is formed within the region of the picture element electrode to be polished. An active matrix substrate has such picture element electrodes as mentioned above. <IMAGE> <IMAGE></p> |
