    摘要: NFET and PFET devices with separately stressed channel regions, and methods of their fabrication is disclosed. A FET is disclosed which includes a gate, which gate includes a metal in a first state of stress. The FET also includes a channel region hosted in a single crystal Si based material, which channel region is overlaid by the gate and is in a second state of stress. The second state of stress of the channel region is of an opposite sign than the first state of stress of the metal included in the gate. The NFET channel is usually in a tensile state of stress, while the PFET channel is usually in a compressive state of stress. The methods of fabrication include the deposition of metal layers by physical vapor deposition (PVD), in such manner that the layers are in stressed states.

    摘要: A method for self-aligned gate patterning is disclosed. Two masks are used to process adjacent semiconductor components, such as an nFET and pFET that are separated by a shallow trench isolation region. The mask materials are chosen to facilitate selective etching. The second mask is applied while the first mask is still present, thereby causing the second mask to self align to the first mask. This avoids the undesirable formation of a stringer over the shallow trench isolation region, thereby improving the yield of a semiconductor manufacturing operation.

    摘要: A structure and method for making includes adjacent PMOSFET and nMOSFET devices in which the gate stacks are each overlain by a stressing layer that provides compressive stress in the channel of the PMOSFET device and tensile stress in the channel of the nMOSFET device. One of the PMOSFET or nMOSFET device has a height shorter than that of the other adjacent device, and the shorter of the two devices is delineated by a discontinuity or opening in the stressing layer overlying the shorter device. In a preferred method for forming the devices a single stressing layer is formed over gate stacks having different heights to form a first type stress in the substrate under the gate stacks, and forming an opening in the stressing layer at a distance from the shorter gate stack so that a second type stress is formed under the shorter gate stack.
