SEMICONDUCTOR DEVICE AND MANUFACTURE THEREOF, DISPLAY DEVICE HAVING ABOVE DESCRIBED SEMICONDUCTOR DEVICE AND SUPPORTING PLATE THEREOF

摘要

PURPOSE: To decrease the leak currents of a semiconductor device which is a semiconductor device used particularly for a matrix display device, such as LCD, and has Schottky diodes formed between the metallic layers on an insulating substrate and semiconductor layers extending on these metallic layers beyond their flanks. CONSTITUTION: The flanks 21 of the Schottky metallic layers 5, 6 are provided with insulators 10. The insulators suppress the leak currents generated from the flanks of the Schottky metallic layers. These insulators are preferably composed of the oxide of the Schottky metals. The oxide is easily formable by local oxidation using, for example, oxygen plasma.
