    摘要: The present invention provides semiconductor structures and a method of fabricating such structures for application of MOSFET devices. The semiconductor structures are fabricated in such a way so that the layer structure in the regions of the wafer where n-MOSFETs are fabricated is different from the layer structure in regions of the wafers where p-MOSFETs are fabricated. The structures are fabricated by first forming a damaged region with a surface of a Si-containing substrate by ion implanting of a light atom such as He. A strained SiGe alloy is then formed on the Si-containing substrate containing the damaged region. An annealing step is then employed to cause substantial relaxation of the strained SiGe alloy via a defect initiated strain relaxation. Next, a strained semiconductor cap such as strained Si is formed on the relaxed SiGe alloy.

    摘要: A method of fabricating a SOI wafer having a gate-quality, thin buried oxide region is provided. The wafer is fabricating by forming a substantially uniform thermal oxide on a surface of a Si-containing layer of a SOI substrate which includes a buried oxide region positioned between the Si-containing layer and a Si-containing substrate layer. Next, a cleaning process is employed to form a hydrophilic surface on the thermal oxide. A carrier wafer having a hydrophilic surface is provided and positioned near the substrate such that the hydrophilic surfaces adjoin each other. Room temperature bonding is then employed to bond the carrier wafer to the substrate. An annealing step is performed and thereafter, the Si-containing substrate of the silicon-on-insulator substrate and the buried oxide region are selectively removed to expose the Si-containing layer.

    摘要: A structure and method are provided in which a stress present in a film is reduced in magnitude by oxidizing the film through atomic oxygen supplied to a surface of the film. In an embodiment, a mask is used to selectively block portions of the film so that the stress is relaxed only in areas exposed to the oxidation process. A structure and method are further provided in which a film having a stress is formed over source and drain regions of an NFET and a PFET. The stress present in the film over the source and drain regions of either the NFET or the PFET is then relaxed by oxidizing the film through exposure to atomic oxygen to provide enhanced mobility in at least one of the NFET or the PFET while maintaining desirable mobility in the other of the NFET and PFET.

Specifically, the method comprises providing an SOI substrate having a buried insulating layer underlying an SOI layer; forming a pad stack atop the SOI layer; forming a block mask having a channel via atop the pad stack; providing a localized oxide region in the SOI layer on top of the buried insulating layer thereby thinning a portion of the SOI layer, the localized oxide region being self-aligned with the channel via; forming a gate in the channel via; removing at least the block mask; and forming source/drain extensions in the SOI layer abutting the thinned portion of the SOI layer. Providing the localized oxide region further comprises implanting oxygen dopant through the channel via into a portion of the SOI layer; and annealing the dopant to create the localized oxide region.

    摘要: An ultra thin SOI MOSFET device structure and method of fabrication is presented. The device has a terminal composed of silicide, which terminal is forming a Schottky contact with the channel. A plurality of impurities are segregated on the silicide/channel interface, and these segregated impurities determine the resistance of the Schottky contact. Such impurity segregation is achieved by a so called silicidation induced impurity segregation process. Silicon substitutional impurities are appropriate for accomplishing such a segregation.
