    摘要: An integrated circuit structure includes a semiconductor substrate, and a first and a second MOS device. The first MOS device includes a first gate dielectric over the semiconductor substrate, wherein the first gate dielectric is planar; and a first gate electrode over the first gate dielectric. The second MOS device includes a second gate dielectric over the semiconductor substrate; and a second gate electrode over the second gate dielectric. The second gate electrode has a height greater than a height of the first gate electrode. The second gate dielectric includes a planar portion underlying the second gate electrode, and sidewall portions extending on sidewalls of the second gate electrode.

    摘要: A semiconductor device using a CESL (contact etch stop layer) to induce strain in, for example, a CMOS transistor channel, and a method for fabricating such a device. A stress-producing CESL, tensile in an n-channel device and compressive in a p-channel device, is formed over the device gate structure as a discontinuous layer. This may be done, for example, by depositing an appropriate CESL, then forming an ILD layer, and simultaneously reducing the ILD layer and the CESL to a desired level. The discontinuity preferably exposes the gate electrode, or the metal contact region formed on it, if present. The upper boundary of the CESL may be further reduced, however, to position it below the upper boundary of the gate electrode.
