    摘要: The present invention provides a method of forming a dual work function metal gate microelectronics device 200. In one aspect, the method includes forming nMOS and pMOS stacked gate structures 315a and 315b. The nMOS and pMOS stacked gate structures 315a and 315b each comprise a gate dielectric 205, a first metal layer, 305 located over the gate dielectric 205 and a sacrificial gate layer 310 located over the first metal layer 305. The method further includes removing the sacrificial gate layer 310 in at least one of the nMOS or pMOS stacked gate structures, thereby forming a gate opening 825 and modifying the first metal layer 305 within the gate opening 825 to form a gate electrode with a desired work function.

    摘要: The present invention provides a system for producing a triple-gate transistor segment (300), utilizing a standard semiconductor substrate (302). The substrate has a plurality of isolation regions (304) formed along its upper surface in a distally separate relationship, defining a channel region (306). A form structure (308) is disposed atop the isolation regions, and defines a channel body area (310) over the channel region. A channel body structure (316) is disposed within the channel body area, and is engineered to provide a blunted corner or edge (318) along a perimeter of its upper exposed surface. The form structure is then removed, and subsequent processing is performed.
