    摘要: Disclosed herein are various methods of forming high mobility fin channels on three dimensional semiconductor devices, such as, for example, FinFET semiconductor devices. In one example, the method includes forming a plurality of spaced-apart trenches in a semiconducting substrate, wherein the trenches define an original fin structure for the device, and wherein a portion of a mask layer is positioned above the original fin structure, forming a compressively-stressed material in the trenches and adjacent the portion of mask layer, after forming the compressively-stressed material, removing the portion of the mask layer to thereby expose an upper surface of the original fin structure, and forming a final fin structure above the exposed surface of the original fin structure.

    摘要: FIN-FET ICs with adjustable FIN-FET channel widths are formed from a semiconductor layer (42). Fins (36) may be etched from the layer (42) and then some (46) locally shortened or the layer (42) may be locally thinned and then fins (46) of different fin heights etched therefrom. Either way provides fins (46) and FIN-FETs (40) with different channel widths W on the same substrate (24). Fin heights (H) are preferably shortened by implanting selected ions (A, B, C, etc.) through a mask (90, 90′, 94, 94′, 97, 97′) to locally enhance the etch rate of the layer (42) or some of the fins (36). The implant(s) (A, B, C, etc.) is desirably annealed and then differentially etched. This thins part(s) (42-i) of the layer (42) from which the fins (46) are then etched or shortens some of the fins (46) already etched from the layer (42). For silicon, germanium is a suitable implant ion. Having fins (42) with adjustable fin heights Hi on the same substrate (24) enables such FIN-FET ICs (40) to avoid channel-width quantization effects observed with prior art uniform fin height FIN-FETs (20).

    摘要: A semiconductor is formed on a (110) silicon (Si) substrate, with improved electron mobility. Embodiments include semiconductor devices having a silicon carbide (SiC) portion in the nFET channel region. An embodiment includes forming an nFET channel region and a pFET channel region in a Si substrate, such as a (110) Si substrate, and forming a silicon carbide (SiC) portion on the nFET channel region. The SiC portion may be formed by ion implantation of C followed by a recrystallization anneal or by epitaxial growth of SiC in a recess formed in the substrate. The use of SiC in the nFET channel region improves electron mobility without introducing topographical differences between NMOS and PMOS transistors.
