    摘要: A semiconductor process and apparatus includes forming NMOS and PMOS transistors (24, 34) with enhanced hole mobility in the channel region of a transistor by selectively relaxing part of a biaxial-tensile strained semiconductor layer (90) in a PMOS device area (97) to form a relaxed semiconductor layer (91), and then epitaxially growing a bi-axially stressed silicon germanium channel region layer (22) prior to forming the NMOS and PMOS gate structures (26, 36) overlying the channel regions, and then depositing a contact etch stop layer (53-56) over the NMOS and PMOS gate structures. Embedded silicon germanium source/drain regions (84) may also be formed adjacent to the PMOS gate structure (70) to provide an additional uni-axial stress to the bi-axially stressed channel region.

    摘要: A semiconductor process and apparatus includes forming channel orientation PMOS transistors (34) with enhanced hole mobility in the channel region of a transistor by epitaxially growing a bi-axially stressed silicon germanium channel region layer (22), alone or in combination with an underlying silicon carbide layer (86), prior to forming a PMOS gate structure (36) overlying the channel region layer, and then depositing a neutral (53) or compressive (55) contact etch stop layer over the PMOS gate structure. Embedded silicon germanium source/drain regions (84) may also be formed adjacent to the PMOS gate structure (70) to provide an additional uni-axial stress to the bi-axially stressed channel region.

    摘要: A method and structure implant a first-type impurity within a substrate to form a channel region within the substrate adjacent a top surface of the substrate; form a gate stack on the top surface of the substrate above the channel region; and implant a second-type impurity within the substrate to form source and drain regions within the substrate adjacent the top surface. The channel region is positioned between the source and drain regions. The second-type impurity has an opposite polarity with respect to the first-type impurity. The method and structure implant a greater concentration of the first-type impurity, relative to a concentration of the first-type impurity within the channel region, to form a primary body doping region within the substrate below (relative to the top surface) the channel region; and to form secondary body doping regions within the substrate below (relative to the top surface) the source and drain regions.
