Abstract: Monolithic FETs including a majority carrier channel in a first high carrier mobility semiconductor material disposed over a substrate. While a mask, such as a gate stack or sacrificial gate stack, is covering a lateral channel region, a spacer of a high carrier mobility semiconductor material is overgrown, for example wrapping around a dielectric lateral spacer, to increase effective spacing between the transistor source and drain without a concomitant increase in transistor footprint. Source/drain regions couple electrically to the lateral channel region through the high-mobility semiconductor spacer, which may be substantially undoped (i.e. intrinsic). With effective channel length for a given lateral gate dimension increased, the transistor footprint for a given off-state leakage may be reduced or off-state source/drain leakage for a given transistor footprint may be reduced, for example.

Abstract: A non-planar gate all-around device and method of fabrication thereby are described. In one embodiment, a multi-layer stack is formed by selectively depositing the entire epi-stack in an STI trench. The channel layer is grown pseudomorphically over a buffer layer. A cap layer is grown on top of the channel layer. In an embodiment, the height of the STI layer remains higher than the channel layer until the formation of the gate. A gate dielectric layer is formed on and all-around each channel nanowire. A gate electrode is formed on the gate dielectric layer and surrounding the channel nanowire.

Abstract: A transistor includes a body of semiconductor material, where the body has laterally opposed body sidewalls and a top surface. A gate structure contacts the top surface of the body. A source region contacts a first one of the laterally opposed body sidewalls and a drain region contacts a second one of the laterally opposed body sidewalls. A first isolation region is under the source region and has a top surface in contact with a bottom surface of the source region. A second isolation region is under the drain region and has a top surface in contact with a bottom surface of the drain region. Depending on the transistor configuration, a major portion of the inner-facing sidewalls of the first and second isolation regions contact respective sidewalls of either a subfin structure (e.g., FinFET transistor configurations) or a lower portion of a gate structure (e.g., gate-all-around transistor configuration).
