    摘要: Methods of fabricating an integrated circuit with a fin-based fuse, and the resulting integrated circuit with a fin-based fuse are provided. In the method, a fin is created from a layer of semiconductor material and has a first end and a second end. The method provides for forming a conductive path on the fin from its first end to its second end. The conductive path is electrically connected to a programming device that is capable of selectively directing a programming current through the conductive path to cause a structural change in the conductive path to increase resistance across the conductive path.

    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: 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.
