    Abstract: A MOS device comprises a gate stack comprising a gate electrode disposed on a gate dielectric, a first spacer and a second spacer formed on laterally opposite sides of the gate stack, a source region proximate to the first spacer, a drain region proximate to the second spacer, and a channel region subjacent to the gate stack and disposed between the source region and the drain region. The MOS device of the invention further includes a buried oxide (BOX) region subjacent to the channel region and disposed between the source region and the drain region. The BOX region enables deeper source and drain regions to be formed to reduce transistor resistance and suicide spike defects while preventing gate edge junction parasitic capacitance.

    Abstract: A method of forming a semiconductor structure comprises forming a first layer of silicon (10) and then forming a second, silicon germanium, layer (12) adjacent the silicon layer (10). A thin third layer of silicon (14) is then formed adjacent the second layer (12). A gate structure is then formed upon the third layer of silicon (14) using convention Complementary Metal Oxide Semiconductor (CMOS) processes. Trenches are then formed into the second layer (12) and the structure is then exposed to a thermal gaseous chemical etchant, for example heated hydrochloric acid. The etchant removes the silicon germanium, thereby forming a Silicon-On­-Nothing structure. Thereafter, conventional CMOS processing techniques are applied to complete the structure as a Metal Oxide Semiconductor Field Effect Transistor, including the formation of spacer walls (28) from silicon nitride, the silicon nitride (30) also filling a cavity formed beneath the third layer of silicon (14) by removal of the silicon germanium.

    Abstract: Silicon carbon is used as a diffusion barrier (18,108) to germanium so that a silicon layer (20,110) can be subsequently formed without being contaminated with germanium. This is useful in separating silicon layers (20, 110) from silicon germanium layers (16,106) in situations in which both silicon and silicon germanium are desired to be present on the same semiconductor device (10) such as for providing different materials for optimizing carrier mobility between N and P channel transistors (27) and for a raised source/drain (134,136) of silicon in the case of a silicon germanium body.

    Abstract: A multiple-channel semiconductor device has fully or partially depleted quantum wells and is especially useful in ultra large scale integration devices, such as CMOSFETs. Multiple channel regions (15) are provided on a substrate (12) with a gate electrode (16) formed on the uppermost channel region (15), separated by a gate oxide (14c), for example. The vertical stacking of multiple channels (15) and the gate electrode (16) permit increased drive current in a semiconductor device without increasing the silicon area occupied by the device.
