    摘要: A method for manufacturing a transistor includes providing a transistor assembly having a semiconductor layer with a first surface, a dielectric layer disposed on the first surface, a gate electrode disposed on the dielectric layer, an insulation layer adjacent at least part of the gate electrode, and a nitride spacer layer adjacent at least part of the insulation layer. The method also includes depositing, on part of the first surface, a material that will react with the semiconductor layer to form silicide and removing the unreacted material. The method further includes etching the nitride spacer layer, depositing a pre-metal spacer layer adjacent at least part of the nitride spacer layer and at least part of the first surface, etch removing a portion of the pre-metal spacer layer to expose part of the silicided portion of the first surface, and forming a contact with the silicided portion of the first surface.

    摘要: A method of fabricating different transistor structures with the same mask. A masking layer (214) has two openings (204, 202) that expose two transistor areas (304,302). The width of the second opening (202) is adjusted such that the angled implant is substantially blocked from the second transistor area (302). The angled implant forms pocket regions in the first transistor area (304). The same masking layer (214) may then be used to implant source and drain extension regions in both the first and second transistor areas (304, 302).

    摘要: A lateral MOSFET (100) and a method for making the same. A two layer raised source/drain region (106) is located adjacent a gate structure (112). The first layer (106a) of the raised source drain is initially doped p-type and the second layer (106b) of the raised source/drain region is doped n-type. P-type dopants from first layer (106a) are diffused into the substrate to form a pocket barrier region (105). N-type dopants from second layer (106b) diffuse into first layer (106a) so that it becomes n-type and into the substrate to form source/drain junction regions (104). P-type pocket barrier region (105) thus provides a barrier between the source/drain junction regions (104) and the channel region (108).

    摘要: Transistors may be fabricated by isolating a first region (16) of a semiconductor layer from a second region (18) of the semiconductor layer (12). A first disposable gate structure (26) of the first transistor may be formed over the first region (16) of the semiconductor layer (12). The first disposable gate structure (26) may comprise a replaceable material. A second disposable gate structure (28) of the second complementary transistor may be formed over the second region (18) of the semiconductor layer (12). A replacement layer (70) may be formed over the first disposable gate structure (26). The replacement layer (70) may comprise a replacement material. At least a portion of the replaceable material of the first disposable gate structure (26) may be substitutionally replaced with the replacement material of the replacement layer (70) to form a first gate structure (80).
