  • Publication number: 20150129933
    Abstract: When forming field effect transistors with a semiconductor alloy layer, e.g., SiGe, embedded in the source/drain regions, a strategy called tucking has been developed in order to improve formation of the semiconductor alloy layer. An improved tucking strategy is hereby proposed, wherein the interface between the isolation region and the active region is not straight, but it rather defines an indentation, so that the active region protrudes into the isolation region in correspondence to the indentation. A gate is then formed on the surface of the device in such a way that a portion of the indentation is covered by the gate. An etching process is then performed, during which the gate acts as a screen. The etching thus gives rise to a cavity defined by a sidewall comprising portions exposing silicon, alternated to portions exposing the dielectric material of the isolation region.

  • Publication number: 20150129967
    Abstract: Circuit module designs that incorporate dual gate field effect transistors are implemented with fully depleted silicon-on-insulator (FD-SOI) technology. Lowering the threshold voltages of the transistors can be accomplished through dynamic secondary gate control in which a back-biasing technique is used to operate the dual gate FD-SOI transistors with enhanced switching performance. Consequently, such transistors can operate at very low core voltage supply levels, down to as low as about 0.4 V, which allows the transistors to respond quickly and to switch at higher speeds. Performance improvements are shown in circuit simulations of an inverter, an amplifier, a level shifter, and a voltage detection circuit module.
