| 20090090949 | SEMICONDUCTOR DEVICE AND METHOD OF MANUFACTURING THE SAME - A semiconductor device includes: an active region insulated by an element-isolation insulating film embedded on a semiconductor substrate; multiple element forming sections that are provided in the active region; a semiconductor element that is formed in each of the element forming sections; and a channel stopper that is provided in the active region to insulate the element forming sections from each other. The channel stopper comprises: a fin that protrudes between grooves provided in the element-isolation insulating film and on both sides of the active region; a dummy-gate insulating film that covers the fin; and a dummy gate electrode that straddles the fin. | 04-09-2009 |
