Abstract:
A method of manufacturing a semiconductor device is disclosed. The method includes forming a first insulting layer on a substrate, forming a first conductor pattern in the first insulating layer, forming a second insulating layer on the first insulating layer, and forming a second wiring pattern and a contact via in the second insulating layer, wherein a top surface of the first insulating layer is higher than a top surface of the first conductor pattern.

Claim (Index 18):
The method of  claim 14 , wherein the forming the first via and the forming the third conductor pattern comprise:\n forming a second insulating layer on the first insulating layer and on the first and second conductor patterns; forming a first mask pattern on the second insulating layer; forming a second mask pattern on the first mask pattern; forming a preliminary first via hole in an upper portion of the second insulating layer using the second mask pattern as an etching mask, the preliminary first via hole vertically overlapping the first conductor pattern and a portion of the first insulating layer adjacent to the first conductor pattern; and after forming the preliminary first via hole, etching the second insulating layer using the first mask pattern as an etching mask to form a first via hole in a lower portion of the second insulating layer and to form a trench in an upper portion of the second insulating layer.
