    Abstract: An integrated circuit structure includes a fin field-effect transistor (FinFET) including a semiconductor fin over and adjacent to insulation regions; and a source/drain region over the insulation regions. The source/drain region includes a first and a second semiconductor region. The first semiconductor region includes silicon and an element selected from the group consisting of germanium and carbon, wherein the element has a first atomic percentage in the first semiconductor region. The first semiconductor region has an up-slant facet and a down-slant facet. The second semiconductor region includes silicon and the element. The element has a second atomic percentage lower than the first atomic percentage. The second semiconductor region has a first portion on the up-slant facet and has a first thickness. A second portion of the second semiconductor region, if any, on the down-slant facet has a second thickness smaller than the first thickness.

    Abstract: A composite semiconductor structure and method of forming the same are provided. The composite semiconductor structure includes a first silicon-containing compound layer comprising an element selected from the group consisting essentially of germanium and carbon; a silicon layer on the first silicon-containing compound layer, wherein the silicon layer comprises substantially pure silicon; and a second silicon-containing compound layer comprising the element on the silicon layer. The first and the second silicon-containing compound layers have substantially lower silicon concentrations than the silicon layer. The composite semiconductor structure may be formed as source/drain regions of metal-oxide-semiconductor (MOS) devices.

    Abstract: A method includes providing a substrate comprising a substrate material, a gate dielectric film above the substrate, and a first spacer adjacent the gate dielectric film. The spacer has a first portion in contact with a surface of the substrate and a second portion in contact with a side of the gate dielectric film. A recess is formed in a region of the substrate adjacent to the spacer. The recess is defined by a first sidewall of the substrate material. At least a portion of the first sidewall underlies at least a portion of the spacer. The substrate material beneath the first portion of the spacer is reflowed, so that a top portion of the first sidewall of the substrate material defining the recess is substantially aligned with a boundary between the gate dielectric film and the spacer. The recess is filled with a stressor material.

    Abstract: A method for fabricating an integrated device is disclosed. A protective layer is formed over a gate structure when forming epitaxial (epi) features adjacent to another gate structure uncovered by the protective layer. The protective layer is thereafter removed after forming the epitaxial (epi) features. The disclosed method provides an improved method for removing the protective layer without substantial defects resulting. In an embodiment, the improved formation method is achieved by providing a protector over an oxide-base material, and then removing the protective layer using a chemical comprising hydrofluoric acid.
