    摘要: A method for forming a three dimensional device. The method may include directing ions to an end surface of an extension region of a fin structure, the fin structure extending perpendicularly from a substrate plane and having a fin axis parallel to the substrate plane, wherein the ions have trajectories extending in a plane perpendicular to the substrate plane and parallel to the fin axis, wherein a portion of the fin structure is covered by a gate structure defining a channel region, and wherein the end surface is not covered by the gate structure.

    摘要: Variation resistant metal-oxide-semiconductor field effect transistors (MOSFETs) are manufactured using a high-K, metal-gate 'channel-last' process. A cavity is formed between spacers formed over a well area having separate drain and source areas, and then a recess into the well area is formed. The active region is formed in the recess, comprising an optional narrow highly doped layer, essentially a buried epitaxial layer, over which a second un-doped or lightly doped layer is formed which is a channel epitaxial layer. The high doping beneath the low doped epitaxial layer can be achieved utilizing low-temperature epitaxial growth with single or multiple delta doping, or slab doping. A high-K dielectric stack is formed over the channel epitaxial layer, over which a metal gate is formed within the cavity boundaries. In one embodiment of the invention a cap of poly-silicon or amorphous silicon is added on top of the metal gate.

    摘要: Methods for fabricating a FinFET structure are provided. One method comprises forming a hard mask layer (204) on a gate-forming material layer (202) having a first portion (218, 230) and a second portion (234, 232). A plurality of mandrels (210) are fabricated on the hard mask layer and overlying the first portion and the second portion of the gate-forming material layer. A sidewall spacer material layer (214) is deposited overlying the plurality of mandrels. The sidewall spacer material layer overlying the first portion of the gate-forming material layer is partially etched. Sidewall spacers (220, 222, 228) are fabricated from the sidewall spacer material layer, the sidewall spacers being adjacent sidewalls of the plurality of mandrels. The plurality of mandrels are removed, the hard mask layer is etched using the sidewall spacers as an etch mask, and the gate-forming material layer is etched using the etched hard mask layer as an etch mask.
