    摘要: Field effect transistor with increased charge carrier mobility due to stress in the current channel 22. The stress is in the direction of current flow (longitudinal). In PFET devices, the stress is compressive; in NFET devices, the stress is tensile. The stress is created by a compressive film 34 in an area 32 under the channel. The compressive film pushes up on the channel 22, causing it to bend. In PFET devices, the compressive film is disposed under ends 31 of the channel (e.g. under the source and drain), thereby causing compression in an upper portion 22A of the channel. In NFET devices, the compressive film is disposed under a middle portion 40 of the channel (e.g. under the gate), thereby causing tension in the, upper portion of the channel. Therefore, both NFET and PFET devices can be enhanced. A method for making the devices is included.

    摘要: A planar silicon-on-insulator (SOI) structure and a process for fabricating the structure. The SOI structure has a silicon wafer, an oxide layer, and a silicon layer. Trenches are formed, extending from the top surface of the structure to the silicon wafer, and are filled with a semiconductor. The trenches have a top, a bottom, and side walls. The side walls have side-wall silicon portions. The side-wall silicon portions of the trench side walls are covered by trench side-wall oxide layers. A protective side wall extends over the trench side walls and trench side-wall oxide layers from the trench top to the trench bottom.

    摘要: An SOI substrate has a gettering layer of silicon-germanium (SiGe) with 5-10% Ge, and a thickness of approximately 50-1000 nm. Carbon (C) may be added to SiGe to stabilize the dislocation network. The SOI substrate may be a SIMOX SOI substrate, or a bonded SOI substrate, or a seeded SOI substrate. The gettering layer may disposed under a buried oxide (BOX) layer. The gettering layer may be disposed on a backside of the substrate.

    摘要: A process for making a SOI region and a bulk region in a semiconductor device. The process includes providing a SOI structure. The SOI structure has a thin silicon layer, a buried insulating oxide layer underlying the thin silicon layer, and a silicon substrate underlying the buried insulating oxide layer. Next, a nitride layer is deposited on top of the SOI structure. The SOI structure is exposed by selectively etching portions of the nitride layer. The portion of the nitride layer which is not etched forms the SOI region. The silicon substrate is exposed by selectively etching the remaining portion of the exposed SOI structure. An epitaxial layer is grown in top of the exposed silicon substrate to form the bulk region. The nitride portion above the SOI structure is finally removed.
