发明名称 SEMICONDUCTOR DEVICE AND METHOD FOR FORMING THE SAME
摘要 A semiconductor and a method for forming the same are disclosed. The method for forming the semiconductor device includes forming a buried gate on a semiconductor substrate including an active region, forming an insulating layer on the semiconductor substrate, selectively removing the insulating layer from at least an upper part of the active region, forming a bit line on an upper part between the buried gates formed on the active region, and forming a storage electrode contact that is formed at both sides of the bit line and has an extended lower part, so that prevents short circuiting between the storage electrode contact and the bit line, and improves contact resistance by enlarging a contact area between the storage electrode contact and the active region, so that unique characteristics of the semiconductor device are improved.
