| 20110294278 | METHOD FOR MANUFACTURING SEMICONDUCTOR DEVICE - A method for manufacturing a semiconductor device which prevents damage to alignment marks used for alignment between a superjunction structure and process layers at subsequent steps. In the related art, recesses are made in a semiconductor substrate before the formation of the superjunction structure and used as alignment marks and in order to prevent damage to the alignment marks, the alignment marks are covered by an insulating film such as a silicon oxide film during the subsequent process of forming the superjunction structure, but the inventors have found that damage may penetrate the cover film, reach the semiconductor substrate and destroy the marks. In the method according to the invention, alignment marks for alignment between the superjunction structure and process layers at subsequent steps are formed after the formation of the superjunction structure. | 12-01-2011 |
