A methodology for forming a single diffusion break structure in a FinFET device involves localized, in situ oxidation of a portion of a semiconductor fin. Fin oxidation within a fin cut region may be preceded by the formation of epitaxial source/drain regions over the fin, as well as by a gate cut module, where portions of a sacrificial gate that straddle the fin are replaced by an isolation layer. Localized oxidation of the fin enables the stress state in adjacent, un-oxidized portions of the fin to be retained, which may beneficially impact carrier mobility and hence conductivity within channel portions of the fin.

A structure, an STI structure and a related method are disclosed. The structure may include an active region extending from a substrate; a gate extending over the active region; and a source/drain region in the active region, and an STI structure. The STI structure includes a liner and a fill layer on the liner along the opposed longitudinal sides of a lower portion of the active region, and the fill layer along the opposed ends of the active region. The liner may include a tensile stress-inducing liner that imparts a transverse-to-length tensile stress in at least a lower portion of the active region but not lengthwise. The liner can be applied in an n-FET region and/or a p-FET region to improve performance.

First and second fin-type field effect transistors (finFETs) are formed laterally adjacent one another extending from a top surface of an isolation layer. The first finFET has a first fin structure and the second finFET has a second fin structure. An insulator layer is on the first fin structure and the second fin structure. A gate conductor intersects the first fin structure and the second fin structure, and at least the insulator layer separates the gate conductor from the first fin structure and the second fin structure. Source and drain structures are on the first fin structure and the second fin structure laterally adjacent the gate conductor. The first fin structure has sidewalls that include a step and the second fin structure has sidewalls that do not include the step. The step is approximately parallel to the surface of the isolation layer.

Aspects of the present invention generally relate to approaches for forming a semiconductor device such as a TSV device having a “buffer zone” or gap layer between the TSV and transistor(s). The gap layer is typically filled with a low stress, thin film fill material that controls stresses and crack formation on the devices. Further, the gap layer ensures a certain spatial distance between TSVs and transistors to reduce the adverse effects of temperature excursion.
