    Abstract: One illustrative method disclosed herein includes, among other things, removing at least one, but not all, of a plurality of first features in a first patterned mask layer so as to define a modified first patterned masking layer, wherein removed first feature(s) correspond to a location where a final isolation structure will be formed, performing an etching process though the modified first patterned masking layer to form an initial isolation trench in the substrate, and performing another etching process through the modified first patterned mask layer to thereby define a plurality of fin-formation trenches in the substrate and to extend a depth of the initial isolation trench so as to define a final isolation trench for the final isolation structure.

    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: Approaches for enabling uniform epitaxial (epi) growth in an epi junction area of a semiconductor device (e.g., a fin field effect transistor device) are provided. Specifically, a semiconductor device is provided including a dummy gate and a set of fin field effect transistors (FinFETs) formed over a substrate; a spacer layer formed over the dummy gate and each of the set of FinFETs; and an epi material formed within a set of recesses in the substrate, the set of recesses formed prior to removal of an epi block layer over the dummy gate.

    Abstract: In a non-planar based semiconductor process where the structure includes both N and P type raised structures (e.g., fins), and where a different type of epitaxy is to be grown on each of the N and P type raised structures, prior to the growing, a lithographic blocking material over one of the N and P type raised structure portions is selectively etched to expose and planarize a gate cap. After the first type of epitaxy is grown, the process is repeated for the other of the N and P type epitaxy.
