    摘要: Disclosed is an integrated circuit having at least one deep trench isolation structure and a deep trench capacitor. A method of forming the integrated circuit incorporates a single etch process to simultaneously form first trench(s) and a second trenches for the deep trench isolation structure(s) and a deep trench capacitor, respectively. Following formation of a buried capacitor plate adjacent to the lower portion of the second trench, the trenches are lined with a conformal insulator layer and filled with a conductive material. Thus, for the deep trench capacitor, the conformal insulator layer functions as the capacitor dielectric and the conductive material as a capacitor plate in addition to the buried capacitor plate. A shallow trench isolation (STI) structure formed in the substrate extending across the top of the first trench(es) encapsulates the conductive material therein, thereby creating the deep trench isolation structure(s).

    摘要: Disclosed is an integrated circuit device having stacked fin-type field effect transistors (FINFETs) with integrated voltage equalization and a method. A multi-layer fin includes a semiconductor layer, an insulator layer above the semiconductor layer and a high resistance conductor layer above the insulator layer. For each FINFET, a gate is positioned on the sidewalls and top surface of the fin and source/drain regions are within the semiconductor layer on both sides of the gate. Thus, the portion of the semiconductor layer between any two gates contains a source/drain region of one FINFET abutting a source/drain region of another. Conductive straps are positioned on opposing ends of the fin and also between adjacent gates in order to electrically connect the semiconductor layer to the conductor layer. Contacts electrically connect the conductive straps at the opposing ends of the fin to positive and negative supply voltages, respectively.

    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.

    摘要: Methods for fabricating dual-depth trench isolation regions for a memory cell. First and second deep trench isolation regions are formed in the semiconductor layer that laterally bound a device region in a well of a first conductivity type in the semiconductor layer. First and second pluralities of doped regions of a second conductivity type are formed in the device region. A shallow trench isolation region is formed that extends laterally across the device region from the first deep trench isolation region to the second deep trench isolation region. The shallow trench isolation region is disposed in the device region between the first and second pluralities of doped regions. The shallow trench isolation region extends into the semiconductor layer to a depth such that the well is continuous beneath the shallow trench isolation region. A gate stack controls carrier flow between a pair of the first plurality of doped regions.

    摘要: A recessed gate FET device includes a substrate having an upper and lower portions, the lower portion having a reduced concentration of dopant material than the upper portion; a trench-type gate electrode defining a surrounding channel region and having a gate dielectric material layer lining and including a conductive material having a top surface recessed to reduce overlap capacitance with respect to the source and drain diffusion regions formed at an upper substrate surface at either side of the gate electrode. There is optionally formed halo implants at either side of and abutting the gate electrode, each halo implants extending below the source and drain diffusions into the channel region. Additionally, highly doped source and drain extension regions are formed that provide a low resistance path from the source and drain diffusion regions to the channel region. The recessed gate FET device suppresses short channel effects and exhibits improved threshold voltage (Vt) characteristics at corners of the trench bottom.

    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.
