    摘要: A FET has a shallow source/drain region, a deep channel region, a gate stack and a back gate that is surrounded by dielectric. The FET structure also includes halo or pocket implants that extend through the entire depth of the channel region. Because a portion of the halo and well doping of the channel is deeper than the source/drain depth, better threshold voltage and process control is achieved. A back-gated FET structure is also provided having a first dielectric layer in this structure that runs under the shallow source/drain region between the channel region and the back gate. This first dielectric layer extends from under the source/drain regions on either side of the back gate and is in contact with a second dielectric such that the back gate is bounded on each side or isolated by dielectric.

    摘要: Disclosed herein are embodiments of an improved method of forming p-type and n-type MUGFETs with high mobility crystalline planes in high-density, chevron-patterned, CMOS devices. Specifically, semiconductor fins are formed in a chevron layout oriented along the centerline of a wafer. Gates are formed adjacent to the semiconductor fins such that they are approximately perpendicular to the centerline. Then, masked implant sequences are performed, during which halo and/or source/drain dopants are implanted into the sidewalls of the semiconductor fins on one side of the chevron layout and then into the sidewalls of the semiconductor fins on the opposite side of the chevron layout. The implant direction used during these implant sequences is substantially orthogonal to the gates in order to avoid mask shadowing, which can obstruct dopant implantation when separation between the semiconductor fins in the chevron layout is scaled (i.e., when device density is increased).

    摘要: Disclosed herein are embodiments of a design structure of a multiple fin fin-type field effect transistor (i.e., a multiple fin dual-gate or tri-gate field effect transistor) in which the multiple fins are partially or completely merged by a highly conductive material (e.g., a metal silicide). Merging the fins in this manner allow series resistance to be minimized with little, if any, increase in the parasitic capacitance between the gate and source/drain regions. Merging the semiconductor fins in this manner also allows each of the source/drain regions to be contacted by a single contact via as well as more flexible placement of that contact via.

    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.

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.

    摘要: Disclosed are embodiments of a field effect transistor with a gate-to-body tunnel current region (GTBTCR) and a method. In one embodiment, a gate, having adjacent sections with different conductivity types, traverses the center portion of a semiconductor layer to create, within the center portion, a channel region and a GTBTCR below the adjacent sections having the different conductivity types, respectively. In another embodiment, a semiconductor layer has a center portion with a channel region and a GTBTCR. The GTBTCR comprises: a first implant region adjacent to and doped with a higher concentration of the same first conductivity type dopant as the channel region; a second implant region, having a second conductivity type, adjacent to the first implant region; and an enhanced generation and recombination region between the implant regions. A gate with the second conductivity type traverses the center portion.
