    Abstract: Disclosed is an integrated circuit having an asymmetric FET as a power gate for an electronic circuit, which has at least two stacked symmetric field effect transistors. The asymmetric FET has an asymmetric halo configuration (i.e., a single source-side halo or a source-side halo with a higher dopant concentration than a drain-side halo) and an asymmetric source/drain extension configuration (i.e., the source extension can be overlapped to a greater extent by the gate structure than the drain extension and/or the source extension can have a higher dopant concentration than the drain extension). As a result, the asymmetric FET has a low off current. In operation, the asymmetric FET is turned off when the electronic circuit is placed in a standby state and, due to the low off current (Ioff), effectively reduces standby leakage current from the electronic circuit. Additionally, avoiding the use of stacked asymmetric field effect transistors within the electronic circuit itself prevents performance degradation due to reduced linear drain current (Idlin).

    Abstract: A method that forms a structure implants a well implant into a substrate, patterns a mask on the substrate (to have at least one opening that exposes a channel region of the substrate) and forms a conformal dielectric layer on the mask and to line the opening. The conformal dielectric layer covers the channel region of the substrate. The method also forms a conformal gate metal layer on the conformal dielectric layer, implants a compensating implant through the conformal gate metal layer and the conformal dielectric layer into the channel region of the substrate, and forms a gate conductor on the conformal gate metal layer. Additionally, the method removes the mask to leave a gate stack on the substrate, forms sidewall spacers on the gate stack, and then forms source/drain regions in the substrate partially below the sidewall spacers.

    Abstract: Disclosed are embodiments of a metal oxide semiconductor field effect transistor (MOSFET) structure and a method of forming the structure. The structure incorporates source/drain regions and a channel region between the source/drain regions. The source/drain regions can comprise silicon, which has high diffusivity to the source/drain dopant. The channel region can comprise a silicon alloy selected for optimal charge carrier mobility and band energy and for its low source/drain dopant diffusivity. During processing, the source/drain dopant can diffuse into the edge portions of the channel region. However, due to the low diffusivity of the silicon alloy to the source/drain dopant, the dopant does not diffuse deep into channel region. Thus, the edge portions of the silicon alloy channel region can have essentially the same dopant profile as the source/drain regions, but a different dopant profile than the center portion of the silicon alloy channel region.

    Abstract: Disclosed is an integrated circuit device having series-connected planar or non-planar field effect transistors (FETs) with integrated voltage equalization and a method of forming the device. The series-connected FETs comprise gates positioned along a semiconductor body to define the channel regions for the series-connected FETs. Source/drain regions are located within the semiconductor body on opposing sides of the channel regions such that each portion of the semiconductor body between adjacent gates comprises one source/drain region for one field effect transistor abutting another source/drain region for another field effect transistor. Integrated voltage equalization is achieved through a conformal conductive layer having a desired resistance and positioned over the series-connected FETs such that it is electrically isolated from the gates, but in contact with the source/drain regions within the semiconductor body.

    Abstract: 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).
