Abstract:
A method of forming a FinFET device involves performing an epitaxial growth process to form a layer of semiconducting material on a semiconducting substrate, wherein a first portion of the layer of semiconducting material will become a fin structure for the FinFET device and wherein a plurality of second portions of the layer of semiconducting material will become source/drain structures of the FinFET device, forming a gate insulation layer around at least a portion of the fin structure and forming a gate electrode above the gate insulation layer.

Abstract:
An approach for controlling a critical dimension (CD) of a RMG of a semiconductor device is provided. Specifically, embodiments of the present invention allow for CD consistency between a dummy gate and a subsequent RMG. In a typical embodiment, a dummy gate having a cap layer is formed over a substrate. A re-oxide layer is then formed over the substrate and around the dummy gate. A set of doping implants will then be implanted in the substrate, and the re-oxide layer will subsequently be removed (after the set of doping implants have been implanted). A set of spacers will then be formed along a set of side walls of the dummy gate and an epitaxial layer will be formed around the set of side walls. Thereafter, the dummy gate will be replaced with a metal gate (e.g., an aluminum or tungsten body having a high-k metal liner there-around).

Abstract:
Aspects of the present invention relate to an approach for implanting and forming a polysilicon resistor with a single implant dose. Specifically, a mask having a set of openings is formed over a resistor surface. The set of openings are typically formed in a column-row arrangement according to a predetermined pattern. Forming the mask in this manner allows the resistor surface to have multiple regions/zones. A first region is defined by the set of openings in the mask, and a second region is defined by the remaining portions of the mask. The resistor is then subjected to a single implant dose via the openings. Implanting the resistor in this manner allows the resistor to have multiple resistance values (i.e., a first resistance value in the first region, and a second resistance value in the second region).
