    摘要: An integrated circuit having devices fabricated in both SOI regions and bulk regions, wherein the regions are connected by a trench filled with epitaxially deposited material. The filled trench provides a continuous semiconductor surface joining the SOI and bulk regions. The SOI and bulk regions may have the same or different crystal orientations. The present integrated circuit is made by forming a substrate with SOI and bulk regions separated by an embedded sidewall spacer (made of dielectric). The sidewall spacer is etched, forming a trench that is subsequently filled with epitaxial material. After planarizing, the substrate has SOI and bulk regions with a continuous semiconductor surface. A butted P-N junction and silicide layer can provide electrical connection between the SOI and bulk regions.

    摘要: Disclosed are planar and non-planar field effect transistor (FET) structures and methods of forming the structures. The structures comprise segmented active devices (e.g., multiple semiconductor fins for a non-planar transistor or multiple semiconductor layer sections for a planar transistor) connected at opposite ends to source/drain bridges. A gate electrode is patterned on the segmented active devices between the source/drain bridges such that it has a reduced length between the segments (i.e., between the semiconductor fins or sections). Source/drain contacts land on the source/drain bridges such that they are opposite only those portions of the gate electrode with the reduced gate length. These FET structures can be configured to simultaneously maximize the density of the transistor, minimize leakage power and maintain the parasitic capacitance between the source/drain contacts and the gate conductor below a preset level, depending upon the performance and density requirements.
