    摘要: A method of forming a multiple-thickness semiconductor-on-insulator, comprising the following steps. A wafer is provided comprising a semiconductor film (having at least two regions) overlying a buried insulator layer overlying a substrate. The semiconductor film within one of the at least two regions is masked to provide at least one semiconductor film masked portion having a first thickness, leaving exposed the semiconductor film within at least one of the at least two regions to provide at least one semiconductor film exposed portion having the first thickness. In one embodiment, at least a portion of the at least one exposed semiconductor film portion is oxidized to provide at least one partially oxidized, exposed semiconductor film portion. Then the oxidized portion of the exposed semiconductor film is removed to leave a portion of the semiconductor film having a second thickness less than the first thickness.

    摘要: A method of fabricating a CMOS device wherein mobility enhancement of both the NMOS and PMOS elements is realized via strain induced band structure modification, has been developed. The NMOS element is formed featuring a silicon channel region under biaxial strain while the PMOS element is simultaneously formed featuring a SiGe channel region under biaxial compressive strain. A novel process sequence allowing formation of a thicker silicon layer overlying a SiGe layer, allows the NMOS channel region to exist in the silicon layer overlying a SiGe layer, allows the NMOS channel region to exist in the silicon layer which is under biaxial tensile strain enhancing electron mobility. The same novel process sequence results in the presence of a thinner silicon layer, overlying the same SiGe layer in the PMOS region, allowing the PMOS channel region to exist in the biaxial compressively strained SiGe layer, resulting in hole mobility enhancement.

    摘要: A method for forming a gate electrode for a multiple gate transistor provides a doped, planarized gate electrode material which may be patterned using conventional methods to produce a gate electrode that straddles the active area of the multiple gate transistor and has a constant transistor gate length. The method includes forming a layer of gate electrode material having a non-planar top surface, over a semiconductor fin. The method further includes planarizing and doping the gate electrode material, without doping the source/drain active areas, then patterning the gate electrode material. Planarization of the gate electrode material may take place prior to the introduction and activation of dopant impurities or it may follow the introduction and activation of dopant impurities. After the gate electrode is patterned, dopant impurities are selectively introduced to the semiconductor fin to form source/drain regions.

    摘要: In a method of manufacturing a semiconductor device, a semiconductor layer is patterned to form a source region, a channel region, and a drain region in the semiconductor layer. The channel region extends between the source region and the drain region. Corners of the channel region are rounded by annealing the channel region to form a nano-rod structure. Part of the nano-rod structure is then used as a gate channel. Preferably, a gate dielectric and a gate electrode both wrap around the nano-rod structure, with the gate dielectric being between the nano-rod structure and the gate electrode, to form a transistor device.
