    • A method for forming a contact of a dual stress liner complementary metal oxide semiconductor device is provided to etch via contact openings through overlap domains and non overlap domains of a DSL structure, thereby removing combination mechanisms such as excessive etching of contact domains. An insulating layer is formed on a DSL(Dual Stress Liner) structure. A partial via hole pattern is formed within the insulating layer to the DSL structure. The partial via hole pattern comprises a partial via hole extended to first or second stress liners(140,160) in a non overlap domain of the DSL structure, and a partial via hole extended to the second stress liner in the overlap domain(105) of the DSL structure. In the overlap domain of the DSL structure, a part of the second stress liner layer exposed through partial via holes is selectively etched. The via hole of the overlap domains are extended to the first stress liner. Parts of the first and second stress liner layers exposed through partial via holes at the overlap and non-overlap domains of the DSL structure are simultaneously etched. Via contact holes(301',302',303',304') extended to the via contact domains are formed.
    • 提供了形成双重应力衬垫互补金属氧化物半导体器件的接触的方法,以通过接触开口蚀刻通过DSL结构的重叠域和非重叠域,从而去除组合机制,例如接触域的过度蚀刻。 在DSL(双重应力衬垫)结构上形成绝缘层。 在DSL结构的绝缘层内形成部分通孔图案。 部分通孔图案包括延伸到DSL结构的非重叠区域中的第一或第二应力衬垫(140,160)的部分通孔,以及延伸到所述DSL结构的重叠域(105)中的第二应力衬垫的部分通孔 DSL结构。 在DSL结构的重叠区域中,通过部分通孔暴露的第二应力衬垫层的一部分被选择性地蚀刻。 重叠区域的通孔延伸到第一应力衬垫。 同时蚀刻在DSL结构的重叠和非重叠域处通过部分通孔暴露的第一和第二应力衬垫层的部分。 通过延伸到通孔接触区域的接触孔(301',302',303',304')形成。
