    Abstract: A MOSFET structure and method of forming is described. The method includes forming a metal-containing layer (56) that is thick enough to fully convert the semiconductor layer (22) to a semiconductor metal alloy in a first MOSFET type region (40) but only thick enough to partially convert the semiconductor layer (20) to a semiconductor metal alloy in a second MOSFET type region (30). In one embodiment, the gate stack in a first MOSFET region (40) is recessed prior to forming the metal-containing layer (56) so that the height of the first MOSFET semiconductor stack is less than the height of the second MOSFET semiconductor stack. In another embodiment, the metal-containing layer (56) is thinned over a first type MOSFET region (40) relative to a second type MOSFET region (30) prior to the conversion process.

    Abstract: PROBLEM TO BE SOLVED: To provide a structure and method for reducing a Miller capacitance in a field-effect transistor. SOLUTION: A method for forming a field-effect transistor device includes a step for forming a gate conductor 316 and a gate dielectric on the active device region of an SOI layer formed through an embedded insulator layer 306 on a bulk substrate 308. Source/drain extensions 302 and 304 are formed in the SOI layer adjacent to both sides of the gate conductor, and source/drain sidewall spacers 324 are formed adjacent to the gate conductor. The remaining portion of the SOI layer adjacent to the sidewall spacer is removed to expose a part of the embedded insulator layer. The exposed portion of the embedded insulator layer is removed to expose a part of the bulk substrate. The semiconductor layer is epitaxially grown on the exposed portions of the bulk substrate and the source/drain extensions. The ion-implanted regions 332 and 334 of the source and the drain are formed in the epitaxially grown layer. COPYRIGHT: (C)2007,JPO&INPIT
