    Abstract: In general, in one aspect, a method includes forming a semiconductor substrate having N-diffusion and P-diffusion regions. A gate stack is formed over the semiconductor substrate. A gate electrode hard mask is formed over the gate stack. The gate electrode hard mask is augmented around pass gate transistors with a spacer material. The gate stack is etched using the augmented gate electrode hard mask to form the gate electrodes. The gate electrodes around the pass gate have a greater length than other gate electrodes.

    Abstract: Methods of forming a microelectronic structure are described. Embodiments of those methods may include providing a gate electrode comprising a top surface and first and second laterally opposite sidewalls, wherein a hard mask is disposed on the top surface, a source drain region disposed on opposite sides of the gate electrode, and a spacer disposed on the first and second laterally opposed sidewalls of the gate electrode, forming a silicon germanium layer on exposed portions of the top surface and the first and second laterally opposite sidewalls of the source drain region and then oxidizing a portion of the silicon germanium layer, wherein a germanium portion of the silicon germanium layer is forced down into the source drain region to convert a silicon portion of the source drain region into a silicon germanium portion of the source drain region.

    Abstract: A nonplanar semiconductor device and its method of fabrication is described. The nonplanar semiconductor device includes a semiconductor body having a top surface opposite a bottom surface formed above an insulating substrate wherein the semiconductor body has a pair laterally opposite sidewalls. A gate dielectric is formed on the top surface of the semiconductor body on the laterally opposite sidewalls of the semiconductor body and on at least a portion of the bottom surface of semiconductor body. A gate electrode is formed on the gate dielectric, on the top surface of the semiconductor body and adjacent to the gate dielectric on the laterally opposite sidewalls of semiconductor body and beneath the gate dielectric on the bottom surface of the semiconductor body. A pair source/drain regions are formed in the semiconductor body on opposite sides of the gate electrode.
