Abstract: In a method of forming a CMOS device, first and second conductive structures are formed on a substrate. An insulation layer is formed on the substrate having the first and second conductive structures. The insulation layer is patterned to form an insulation layer pattern having a first portion on the first conductive structure and a second portion on the second conductive structure. The first portion has a compressive stress and functions as an etch stop layer. The second portion functions as an etch stop layer.
