  • Publication number: 20070184594
    Abstract: Disclosed is a silicon-on-insulator-based Schottky barrier diode with a low forward voltage that can be manufactured according to standard SOI process flow. An active silicon island is formed using an SOI wafer. One area of the island is heavily-doped with an n-type or p-type dopant, one area is lightly-doped with the same dopant, and an isolation structure is formed on the top surface above a junction between the two areas. A metal silicide region contacts the lightly-doped side of the island forming a Schottky barrier. Another discrete metal silicide region contacts the heavily-doped area of the island forming an electrode to the Schottky barrier (i.e., a Schottky barrier contact). The two metal silicide regions are isolated from each other by the isolation structure. Contacts to each of the discrete metal silicide regions allow a forward and/or a reverse bias to be applied to the Schottky barrier.

  • Publication number: 20070184602
    Abstract: Disclosed herein is a structure with two different type tri-gate MOSFETs formed on the same substrate. Each MOSFET comprises a fin with optimal mobility for the particular type of MOSFET. Due to the processes used to form fins with different crystalline orientations on the same substrate, one of the MOSFETs has a fin with a lower mobility top surface. To inhibit inversion of the top surface, this MOSFET has a gate dielectric layer with a thicker region on the top surface than it does on the opposing sidewall surfaces. Additionally, several techniques for forming the thicker region of the gate dielectric layer are also disclosed.

  • Publication number: 20070158752
    Abstract: Disclosed is a semiconductor structure and associated method of performing the structure with good performance and stability trade-offs for digital circuits and SRAM cells and/or analog FETs on the same chip. Specifically, a dual-strain layer is formed over digital circuits and the other devices on a chip. The dual-strain layer comprises tensile sections above digital logic n-type transistors, compressive sections above digital logic p-type transistors and additional tensile sections above SRAM cells and/or analog FETs. An amorphization ion-implant is performed to relax the strain over SRAM cell p-FETs and, thereby, eliminate variability and avoid p-FET performance degradation in the SRAM cells. Additionally, this ion-implant can relax the strain above both analog p-FETs and n-FETs and, thereby, eliminate variability and the coupling of the logic device process to the analog FETs and provide more predictable and well-controlled analog FETs.

  • Publication number: 20070158762
    Abstract: 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.

  • Publication number: 20070134864
    Abstract: 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.

  • Publication number: 20070122957
    Abstract: In order to reduce power dissipation requirements, obtain full potential transistor performance and avoid power dissipation limitations on transistor performance in high density integrated circuits, transistors are operated in a sub-threshold (sub-Vth) or a near sub-Vth voltage regime (generally about 0.2 volts rather than a super-Vth regime of about 1.2 volts or higher) and optimized for such operation, particularly through simplification of the transistor structure, since intrinsic channel resistance is dominant in sub-Vth operating voltage regimes. Such simplifications include an underlap or recess of the source and drain regions from the gate which avoids overlap capacitance to partially recover loss of switching speed otherwise caused by low voltage operation, an ultra-thin gate structure having a thickness of 500 ? or less which also simplifies forming connections to the transistor and an avoidance of silicidation or alloy formation in the source, drain and/or gate of transistors.

  • Publication number: 20070111410
    Abstract: An integrated circuit structure has a buried oxide (BOX) layer above a substrate, and a first-type fin-type field effect transistor (FinFET) and a second-type FinFET above the BOX layer. The second region of the BOX layer includes a seed opening to the substrate. The top of the first-type FinFET and the second-type FinFET are planar with each other. A first region of the BOX layer below the first FinFET fin is thicker above the substrate when compared to a second region of the BOX layer below the second FinFET fin. Also, the second FinFET fin is taller than the first FinFET fin. The height difference between the first fin and the second fin permits the first-type FinFET to have the same drive strength as the second-type FinFET.

  • Publication number: 20070108528
    Abstract: 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.

  • Publication number: 20070108537
    Abstract: 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.

  • Publication number: 20070102747
    Abstract: Disclosed is a CNT technology that overcomes the intrinsic ambipolar properties of CNTFETs. One embodiment of the invention provides either a stable p-type CNTFET or a stable n-type CNTFET. Another embodiment of the invention provides a complementary CNT device. In order to overcome the ambipolar properties of a CNTFET, source/drain gates are introduced below the CNT opposite the source/drain electrodes. These source/drain gates are used to apply either a positive or negative voltage to the ends of the CNT so as to configure the corresponding FET as either an n-type or p-type CNTFET, respectively. Two adjacent CNTFETs, configured such that one is an n-type CNTFET and the other is a p-type CNTFET, can be incorporated into a complementary CNT device. In order to independently adjust threshold voltage of an individual CNTFET, a back gate can also be introduced below the CNT and, particularly, below the channel region of the CNT opposite the front gate.
