Method of manufacturing semiconductor device

Abstract:

The present invention relates to a method of fabricating a semiconductor device. According to the method, a first insulating layer having a contact hole formed therein is formed over a semiconductor substrate. A second insulating layer is gap filled within the contact hole. A third insulating layer having a trench formed therein is formed over the semiconductor substrate including the contact hole. The second insulating layer gap filled within the contact hole is removed. A contact plug and a bit line are formed within the contact hole and the trench.

Abstract(Chinese):

本发明涉及半导体器件的制造方法。根据该方法，在半导体衬底上形成有形成有接触孔的第一绝缘层。第二绝缘层在接触孔内填充间隙。形成有沟槽的第三绝缘层形成在包括接触孔的半导体衬底的上方。去除填充在接触孔内的第二绝缘层间隙。接触插塞和位线形成在接触孔和沟槽内。
