    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.

    摘要: Disclosed are embodiments a technique for inducing strain into the polysilicon gate of a non-planar FET (e.g., a finFET or trigate FET) in order to impart a similar strain on the FET channel region, while simultaneously protecting the source/drain regions of the semiconductor fin. Specifically, a protective cap layer is formed above the source/drain regions of the fin in order to protect those regions during a subsequent amporphization ion implantation process. The fin is further protected, during this implantation process, because the ion beam is directed towards the gate in a plane that is parallel to the fin and tilted from the vertical axis. Thus, amorphization of the fin and damage to the fin are limited. Following the implantation process and the formation of a straining layer, a recrystallization anneal is performed so that the strain of the straining layer is ‘memorized’ in the polysilicon gate.

    摘要: A system and method for providing a driver for a multi-voltage island/core architecture of an integrated circuit chip are provided. A complementary metal oxide semiconductor (CMOS) inverter is built with a high threshold voltage p-channel field-effect transistor (hi-Vt PFET) and a regular threshold voltage n-channel field-effect transistor (NFET), which uses the maximum positive voltage supply (Vdd) on the chip. The threshold voltage of the hi-Vt PFET is determined based on the maximum Vdd, the Vdd of the Voltage island/core that drives the CMOS inverter, and a subthreshold leakage current requirement of the hi-Vt PFET.

    摘要: Disclosed is a structure and method for producing a fin-type field effect transistor (FinFET) that has a buried oxide layer over a substrate, at least one first fin structure and at least one second fin structure positioned on the buried oxide layer. First spacers are adjacent the first fin structure and second spacers are adjacent the second fin structure. The first spacers cover a larger portion of the first fin structure when compared to the portion of the second fin structure covered by the second spacers. Those fins that have larger spacers will receive a smaller area of semiconductor doping and those fins that have smaller spacers will receive a larger area of semiconductor doping. Therefore, there is a difference in doping between the first fins and the second fins that is caused by the differently sized spacers. The difference in doping between the first fins and the second fins changes an effective width of the second fins when compared to the first fins.

    摘要: Disclosed are embodiments of a trigate field effect transistor that comprises a fin-shaped semiconductor body with a channel region and source/drain regions on either side of the channel region. Thick gate dielectric layers separate the top surface and opposing sidewalls of the channel region from the gate conductor in order to suppress conductivity in the channel planes. A thin gate dielectric layer separates the upper corners of the channel region from the gate conductor in order to optimize conductivity in the channel corners. To further emphasize the current flow in the channel corners, the source/drain regions can be formed in the upper corners of the semiconductor body alone. Alternatively, source/drain extension regions can be formed only in the upper corners of the semiconductor body adjacent to the gate conductor and deep source/drain diffusion regions can be formed in the ends of the semiconductor body.

    摘要: Disclosed is an SRAM cell on an SOI, bulk or HOT wafer with two pass-gate n-FETs, two pull-up p-FETs and two pull-down n-FETs and the associated methods of making the SRAM cell. The pass-gate FETs and pull-down FETs are non-planar fully depleted finFETs or trigate FETs. The pull-down FETs comprise non-planar partially depleted three-gated FETs having a greater channel width and a greater gate length and, thus, a greater drive current relative to the pass-gate and pull-up FETs. Additionally, for optimal electron mobility and hole mobility, respectively, the channels of the n-FETs and p-FETs can comprise semiconductors with different crystalline orientations.

    摘要: Disclosed is a method of manufacturing dual orientation wafers. A trench is formed in a multi-layer wafer to a silicon substrate with a first crystalline orientation. The trench is filled with a silicon material (e.g., amorphous silicon or polysilicon trench). Isolation structures are formed to isolate the silicon material in the trench from a semiconductor layer with a second crystalline orientation. Additional isolation structures are formed within the silicon material in the trench and within the semiconductor layer. A patterned amorphization process is performed on the silicon material in the trench and followed by a recrystallization anneal such that the silicon material in the trench recrystallizes with the same crystalline orientation as the silicon substrate. The resulting structure is a semiconductor wafer with isolated semiconductor areas on the same plane having different crystalline orientations as well as isolated sections within each semiconductor area for device formation.

    摘要: A semiconductor structure and method for forming the same. The structure includes multiple fin regions disposed between first and second source/drain (S/D) regions. The structure further includes multiple front gates and back gates, each of which is sandwiched between two adjacent fin regions such that the front gates and back gates are alternating (i.e., one front gate then one back gate and then one front gate, and so on). The widths of the front gates are greater than the widths of the back gates. The capacitances of between the front gates and the S/D regions are smaller than the capacitances of between the back gates and the S/D regions. The distances between the front gates and the S/D regions are greater than the distances between the back gates and the S/D regions.
