    摘要: The present invention facilitates semiconductor device fabrication by providing mechanisms for utilizing different isolation schemes within embedded memory and other logic portions of a device. The isolation mechanism of the embedded memory portion is improved relative to other portions of the device by increasing dopant concentrations or reducing the depth of the dopant profiles within well regions of the embedded memory array. As a result, smaller isolation spacing can be employed thereby permitting a more compact array. The isolation mechanism of the logic portion is relatively less than that of the embedded memory portion, which permits greater operational speed for the logic.

    摘要: The present invention facilitates semiconductor fabrication by providing methods of fabrication that selectively apply tensile strain to channel regions of devices while mitigating masking operations employed. A cap poly layer is formed over NMOS and PMOS regions of a semiconductor device. Then, a resist mask is employed to remove a portion of the cap poly layer from the PMOS region. Subsequently, the same resist mask and/or remaining portion of the cap poly layer is employed to form source/drain regions within the PMOS region by implanting a p-type dopant. Afterward, a cap poly thermal process is performed that causes tensile strain to be induced only in channel regions of devices located within the NMOS region. As a result, channel mobility and/or performance of devices located in the PMOS region is not substantially degraded.
