    摘要: Methods and structures for CMOS devices with hybrid crystal orientations using double SOI substrates is provided. In accordance with preferred embodiments, a manufacturing sequence includes the steps of forming an SOI silicon epitaxy layer after the step of forming shallow trench isolation regions. The preferred sequence allows hybrid SOI CMOS fabrication without encountering problems caused by forming STI regions after epitaxy. A preferred device includes an NFET on a {100} crystal orientation and a PFET on a {110} crystal orientation. An NMOS channel may be oriented along the direction, which is the direction of maximum electron mobility for a {100} substrate. A PMOS channel may be oriented along the direction, which is the direction where hole mobility is maximum for a {110} substrate.

    摘要: Disclosed herein are various embodiments of techniques for preventing silicide stringer or encroachment formation during metal salicide formation in semiconductor devices. The disclosed technique involves depositing a protective layer, such as a nitride or other dielectric layer, over areas of the semiconductor device where metal silicide formation is not desired because such formation detrimentally affects device performance. For example, silicon particles that may remain in device features that are formed through silicon oxidation, such as under the gate sidewall spacers and proximate to the perimeter of shallow trench isolation structures, are protected from reacting with metal deposited to form metal silicide in certain areas of the device. As a result, silicide stringers or encroachment in undesired areas is reduced or eliminated by the protective layer.
