    摘要: A semiconductor structure includes a substrate, and a first MOS device on the first region of the substrate wherein the first MOS device includes a first spacer liner. The semiconductor structure further includes a second MOS device on the second region wherein the second MOS device includes a second spacer liner. A first stressed film having a first thickness is formed over the first MOS device and directly on the first spacer liner. A second stressed film having a second thickness is formed over the second MOS device and directly on the second spacer liner. The first and the second stressed films may be formed of a same material.

    摘要: A method of forming an opening on a low-k dielectric layer using a polysilicon hard mask rather than a metal hard mask as used in prior art. A polysilicon hard mask is formed over a low-k dielectric layer and a photoresist layer is formed over the polysilicon hard mask. The photoresist layer is patterned and the polysilicon hard mask is etched with a gas plasma to create exposed portions of the low-k dielectric layer. The photoresist layer in stripped prior to the etching of the exposed portions of the low-k dielectric layer to avoid damage to the low-k dielectric layer.

    摘要: A method that includes forming a masking element on a semiconductor substrate and overlying a defined space. A first feature and a second feature are each formed on the semiconductor substrate. The space interposes the first and second features and extends from a first end of the first feature to a first end of the second feature. A third feature is then formed adjacent and substantially parallel the first and second features. The third feature extends at least from the first end of the first feature to the first end of the second feature.
