SEMICONDUCTOR DEVICE AND ITS MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To embody a technique of forming pixel regions of a high aperture ratio by providing a method for forming holding capacitors with a liquid crystal display device of an IPS system. SOLUTION: The surfaces of common electrodes 103 formed on insulating films, more particularly resin films, used for the respective circuits of an electro- optic device as represented by an LCD consisting of the IPS system are covered with anodically oxidized films by executing an anodic oxidation stage at >=11 V/min in impressed voltage/power feed time, by which the infiltrating amount may be decreased and the liquid crystal display device having the electrodes of an excellent adhesion property and having high reliability may be manufactured.
