    摘要: In one aspect, a method of forming contacts to source and drain regions in a FET device includes the following steps. A patternable dielectric is deposited onto the device so as to surround each of the source and drain regions. The patternable dielectric is exposed to cross-link portions of the patternable dielectric that surround the source and drain regions. Uncross-linked portions of the patternable dielectric are selectively removed relative to the cross-linked portions of the patternable dielectric, wherein the cross-linked portions of the patternable dielectric form dummy contacts that surround the source and drain regions. A planarizing dielectric is deposited onto the device around the dummy contacts. The dummy contacts are selectively removed to form vias in the planarizing dielectric which are then filled with a metal(s) so as to form replacement contacts that surround the source and drain regions.

    摘要: A disposable material layer is first deposited on a graphene layer or a carbon nanotube (CNT). The disposable material layer includes a material that is less inert than graphene or CNT so that a contiguous dielectric material layer can be deposited at a target dielectric thickness without pinholes therein. A gate stack is formed by patterning the contiguous dielectric material layer and a gate conductor layer deposited thereupon. The disposable material layer shields and protects the graphene layer or the CNT during formation of the gate stack. The disposable material layer is then removed by a selective etch, releasing a free-standing gate structure. The free-standing gate structure is collapsed onto the graphene layer or the CNT below at the end of the selective etch so that the bottom surface of the contiguous dielectric material layer contacts an upper surface of the graphene layer or the CNT.

    摘要: A method of fabricating a FET device is provided which includes the following steps. Nanowires/pads are formed in a SOI layer over a BOX layer, wherein the nanowires are suspended over the BOX. A HSQ layer is deposited that surrounds the nanowires. A portion(s) of the HSQ layer that surround the nanowires are cross-linked, wherein the cross-linking causes the portion(s) of the HSQ layer to shrink thereby inducing strain in the nanowires. One or more gates are formed that retain the strain induced in the nanowires. A FET device is also provided wherein each of the nanowires has a first region(s) that is deformed such that a lattice constant in the first region(s) is less than a relaxed lattice constant of the nanowires and a second region(s) that is deformed such that a lattice constant in the second region(s) is greater than the relaxed lattice constant of the nanowires.
