    摘要: Suitable particles may be deposited within an extremely small high-aspect ratio via by flowing the particles in a suspension using supercritical carbon dioxide. The particles may be made up of diblock copolymers or silesquioxane-based materials or oligomers of phobic homopolymers or pre-formed silica-based particles stabilized using diblock copolymers and may include chemical initiators to permit in situ polymerization within the via.

    摘要: Non-planar semiconductor devices having germanium-based active regions with release etch-passivation surfaces are described. For example, a semiconductor device includes a vertical arrangement of a plurality of germanium-rich nanowires disposed above a substrate. Each nanowire includes a channel region having a sulfur-passivated outer surface. A gate stack is disposed on and completely surrounds the channel region of each of the germanium-rich nanowires. The gate stack includes a gate dielectric layer disposed on and surrounding the sulfur-passivated outer surface and a gate electrode disposed on the gate dielectric layer. Source and drain regions are disposed on either side of the channel regions of the germanium-rich nanowires.

    摘要: A metal silicide may be selectively etched by converting the metal silicide to a metal silicate. This may be done using oxidation. The metal silicate may then be removed, for example, by wet etching. A non-destructive low pH wet etchant may be utilized, in some embodiments, with high selectivity by dissolution.
