    摘要: Provided herein are approaches for forming a fin field-effect-transistor (FinFET) device using a partially crystallized fin hard mask. Specifically, a hard mask is patterned over a substrate, and the FinFET device is annealed to form a set of crystallized hard mask elements adjacent a set of non-crystallized hard mask elements. A masking structure is provided over a first section of the patterned hard mask to prevent the set of non-crystallized hard mask elements from being crystallized during the anneal. During a subsequent fin cut process, the non-crystallized mask elements are removed, while crystallized mask elements remain. A set of fins is then formed in the FinFET device according to the location(s) of the crystallized mask elements.

    摘要: Approaches for providing a single spacer, double hardmask dual-epi FinFET are disclosed. Specifically, at least one approach for providing the FinFET includes: forming a set of spacers along each sidewall of a plurality of fins of the FinFET device; forming a first ultra-thin hardmask over the plurality of fins; implanting the first ultra-thin hardmask over a first set of fins from the plurality of fins; removing the first ultra-thin hardmask over a second set of fins from the plurality of fins untreated by the implant; forming an epitaxial (epi) layer over the second set of fins; forming a second ultra-thin hardmask over the FinFET device; implanting the second ultra-thin hardmask; removing the second ultra-thin hardmask over the first set of fins; and growing an epi layer over the first set of fins.

    摘要: An improved method of forming semiconductor fins is disclosed. Cavities are formed by etching a semiconductor substrate to a first depth. A surface treatment layer such as a nitride layer is then deposited or formed on the interior surface of the cavities. The etch then continues deeper, while the surface treatment layer protects the upper portion of the cavities.

    摘要: Aspects of the present invention generally relate to approaches for forming a semiconductor device (e.g., FinFET device) having a gate structure formed on a planar surface thereof. Specifically, a uniform, oxide-fin (OF) surface is formed. Then, a “dummy” gate structure and a set of spacers are formed thereon. Once the gate structure and set of spacers have been formed, the OF surface may be recessed. In one embodiment, the OF surface is uniformly recessed. In another embodiment, the OF surface is selectively recessed to yield a set of fins. In any event, after the recessing, an epitaxial layer is grown and an oxide fill is performed. Then, the “dummy” gate structure is removed (from between the set of spacers) and an oxide recess is performed to yield a set of channel fins between the spacers.
