    Abstract: 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.

    Abstract: Embodiments of the present invention provide a metal gate structure and method of formation. In the replacement metal gate (RMG) process flow, the gate cut process is performed after the metal gate is formed. This allows for a reduced margin between the end of the gate and an adjacent fin. It enables a thinner sacrificial layer on top of the dummy gate, since the gate cut step is deferred. The thinner sacrificial layer improves device quality by reducing the adverse effect of shadowing during implantation. Furthermore, in this process flow, the work function metal layer is terminated along the semiconductor substrate by a capping layer, which reduces undesirable shifts in threshold voltage that occurred in prior methods and structures.
