    Abstract: The present invention facilitates semiconductor fabrication by providing methods of fabrication that form metal silicide gates and mitigate formation of silicide region defects near channel regions. A dielectric layer is formed over a semiconductor device (306). Polysilicon is deposited on the dielectric layer to form a gate electrode layer (308) and a patterning operation is then performed to form gate structures (310). Source/drain regions are formed (320) and the gate structures are tuned to obtain a selected work function (324). A metal is then selectively deposited on only the gate structures (328) and a thermal process is performed that reacts the deposited metal with polysilicon of the gate layer to obtain a metal suicide material (330).

    Abstract: The present invention facilitates semiconductor fabrication by providing methods of fabrication that selectively form high-k dielectric layers within NMOS regions. An I/O dielectric layer is formed in core and I/O regions of a semiconductor device (506). The I/O dielectric layer is removed (508) from the core region of the device. A core dielectric layer is formed in the core region (510). A barrier layer is deposited and patterned to expose the NMOS devices of the core region (512). The core dielectric layer is removed from the core NMOS devices (514). A high-k dielectric layer is formed (514) over the core and I/O regions. Then, the high-k dielectric layer is removed (512) from PMOS regions/devices of the core region and the NMOS and PMOS regions/devices of the I/O region.

    Abstract: Transistors and fabrication methods are presented in which a semiconductor body is deposited in a cavity of a temporary form structure above a semiconductor starting structure. The formed semiconductor body can be epitaxial silicon deposited in the form cavity over a silicon substrate, and includes three body portions, two of which are doped to form source/drains, and the other forming a transistor channel that overlies the starting structure. A gate structure is formed along one or more sides of the channel body portion to create a MOS transistor.

    Abstract: Dual gate dielectric layers are formed on a semiconductor substrate for MOS transistor fabrication. A first dielectric layer (30) is formed on a semiconductor substrate (10). A first plasma nitridation process is performed on said first dielectric layer. The first dielectric layer (30) is removed in regions of the substrate and a second dielectric layer (50) is formed in these regions. A second plasma nitridation process is performed on the first dielectric layer and the second dielectric. MOS transistors (160, 170) are then fabricated using the dielectric layers (30, 50).
