Abstract: The use of two different materials for shallow trench isolation and deep structural trenches with a dielectric material therein (e.g., flowable oxide and a HARP oxide, respectively) causes non-uniform heights of exposed portions of raised semiconductor structures for non-planar semiconductor devices, due to the different etch rates of the materials. Non-uniform openings adjacent the exposed portions of the raised structures from recessing the isolation and dielectric materials are filled with additional dielectric material to create a uniform top layer of one material (the dielectric material), which can then be uniformly recessed to expose uniform portions of the raised structures.

Abstract: A semiconductor structure with mixed n-type and p-type non-planar transistors includes a residual overlapping mask bump on one or more of the dummy gates. A dielectric layer is created over the structure having a top surface above the residual bump, for example, using a blanket deposition and chemical-mechanical underpolish (i.e., stopping before exposing the gate cap). The residual bump is then transformed into a same material as the dielectric, either in its entirety and then removing the combined dielectric, or by removing the dielectric first and partly removing the residual bump, the remainder of which is then transformed and the dielectric removed. In either case, the structure is planarized for further processing.

Abstract: An intermediate semiconductor structure of a FinFET device in fabrication includes a substrate, a plurality of fin structures coupled to the substrate and a dummy gate disposed perpendicularly over the fin structures. A portion of the dummy gate is removed between the fin structures to create one or more vias and the one or more vias are filled with a dielectric. The dummy gate is then replaced with a metal gate formed around the dielectric-filled vias.
