Abstract: Tin oxide films are used as mandrels in semiconductor device manufacturing. In one implementation the process starts by providing a substrate having a plurality of protruding tin oxide features (mandrels) residing on an exposed etch stop layer. Next, a conformal layer of spacer material is formed both on the horizontal surfaces and on the sidewalls of the mandrels. The spacer material is then removed from the horizontal surfaces exposing the tin oxide material of the mandrels, without fully removing the spacer material residing at the sidewalls of the mandrel (e.g., leaving at least 50%, such as at least 90% of initial height at the sidewall). Next, mandrels are selectively removed (e.g., using hydrogen-based etch chemistry), while leaving the spacer material that resided at the sidewalls of the mandrels. The resulting spacers can be used for patterning the etch stop layer and underlying layers.

Abstract: The present disclosure describes an exemplary fabrication method of a p-type fully strained channel that can suppress the formation of {111} facets during a silicon germanium epitaxial growth. The exemplary method includes the formation of silicon epitaxial layer on a top, carbon-doped region of an n-type region. A recess is formed in the silicon epitaxial layer via etching, where the recess exposes the top, carbon-doped region of the n-type region. A silicon seed layer is grown in the recess, and a silicon germanium layer is subsequently epitaxially grown on the silicon seed layer to fill the recess. The silicon seed layer can suppress the formation of growth defects such as, for example, {111} facets, during the silicon germanium epitaxial layer growth.
