    摘要: Contact with a floating body of an FET in SOI may be formed in a portion of one of the two diffusions of the FET, wherein the portion of the diffusion (such as N−, for an NFET) which is “sacrificed” for making the contact is a portion of the diffusion which is not immediately adjacent (or under) the gate. This works well with linked body FETs, wherein the diffusion does not extend all the way to BOX, hence the linked body (such as P−) extends under the diffusion where the contact is being made. An example showing making contact for ground to two NFETs (PG and PD) of a 6T SRAM cell is shown.

    摘要: Arbitrarily and continuously scalable on-currents can be provided for fin field effect transistors by providing two independent variables for physical dimensions for semiconductor fins that are employed for the fin field effect transistors. A recessed region is formed on a semiconductor layer over a buried insulator layer. A dielectric cap layer is formed over the semiconductor layer. Disposable mandrel structures are formed over the dielectric cap layer and spacer structures are formed around the disposable mandrel structures. Selected spacer structures can be structurally damaged during a masked ion implantation. An etch is employed to remove structurally damaged spacer structures at a greater etch rate than undamaged spacer structures. After removal of the disposable mandrel structures, the semiconductor layer is patterned into a plurality of semiconductor fins having different heights and/or different width. Fin field effect transistors having different widths and/or heights can be subsequently formed.

    摘要: A semiconductor structure and its method of fabrication include multiple finFETs with different vertical dimensions for the semiconductor fins. An implant species is implanted in a bottom portion of selected semiconductor fins on which reduced vertical dimension is desired. The bottom portion of the selected semiconductor fins with implant species is etched selective to the semiconductor material without the implanted species, i.e., the semiconductor material in the top portion of the semiconductor fin and other semiconductor fins without the implanted species. FinFETs with the full vertical dimension fins and a high on-current and finFETs with reduced vertical dimension fins with a low on-current thus results on the same semiconductor substrate. By adjusting the depth of the implant species, the vertical dimension of the semiconductor fins may be adjusted in selected finFETs.

Once aspect of the invention concerns CMOS SRAM cell architectures where at least one pair of adjacent NFETs in an SRAM cell have body regions linked by a leakage path diffusion region positioned beneath shallow source/drain diffusions, where the leakage path diffusion region extends from the bottom of the source/drain diffusion to the buried oxide layer, and at least one pair of NFETs from adjacent SRAM cells which have body regions linked by a similar leakage path diffusion region beneath adjacent source/drain diffusions. Another aspect of this invention concerns a microprocessor fabricated on an hybrid orientation substrate where the logic portion of the circuit has NFETs fabricated in (100) crystal orientation SOI silicon regions with floating body regions and PFETs fabricated in (110) crystal orientation bulk silicon regions; and where the SRAM memory portion has NFETs fabricated in (100) crystal orientation SOI silicon regions with body regions linked by leakage path diffusion regions beneath shallow source/drain diffusions and PFETs fabricated in (110) crystal orientation silicon regions.

    摘要: A design structure for a three-dimensional memory circuit provides reduction in memory cell instability due to half-select operation by reduction of the number of memory cells sharing a sense amplifier and, potentially, avoidance of half-select operation by placing some or all peripheral circuits including local evaluation circuits functioning as a type of sense amplifier on an additional chips or chips overlying the memory array. Freedom of placement of such peripheral circuits is provided with minimal increase in connection length since word line decoders may be placed is general registration with any location along the word lines while local evaluation circuits and/or sense amplifiers can be placed at any location generally in registration with the bit line(s) to which they correspond.
