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 13):
The method of  claim 11 , wherein forming the trench and the first and second via holes includes:\n sequentially forming a second etch stop layer and first and second masks on the second insulating interlayer; etching the second etch stop layer and an upper portion of the second insulating interlayer using the first and second masks as an etching mask to form a preliminary via hole overlapping the first wiring and a portion of the first insulating interlayer adjacent to the first wiring; after removing the second mask, etching the second insulating interlayer using the first mask and the second etch stop layer as an etching mask to expose a portion of the first etch stop layer on the first wiring and on the portion of the first insulating interlayer adjacent to the first wiring; removing the exposed portion of the first etch stop layer to expose an upper surface of the first wiring and the portion of the first insulating interlayer adjacent to the first wiring; forming a sacrificial layer on the exposed upper surface of the first wiring and on the exposed portion of the first insulating interlayer; etching the second etch stop layer and the second insulating interlayer using the sacrificial layer and the first mask as an etching mask to expose a portion of the first etch stop layer; and removing the sacrificial layer.
