  • Patent number: 9397097
    Abstract: A semiconductor device and method of fabricating thereof is described that includes a substrate having a fin with a top surface and a first and second lateral sidewall. A hard mask layer may be formed on the top surface of the fin (e.g., providing a dual-gate device). A gate dielectric layer and work function metal layer are formed on the first and second lateral sidewalls of the fin. A silicide layer is formed on the work function metal layer on the first and the second lateral sidewalls of the fin. The silicide layer may be a fully-silicided layer and may provide a stress to the channel region of the device disposed in the fin.

  • Patent number: 9374084
    Abstract: Methods, systems, circuits, and devices for power-packet-switching power converters using bidirectional bipolar transistors (BTRANs) for switching. Four-terminal three-layer BTRANs provide substantially identical operation in either direction with forward voltages of less than a diode drop. BTRANs are fully symmetric merged double-base bidirectional bipolar opposite-faced devices which operate under conditions of high non-equilibrium carrier concentration, and which can have surprising synergies when used as bidirectional switches for power-packet-switching power converters. BTRANs are driven into a state of high carrier concentration, making the on-state voltage drop very low.

  • Patent number: 9355853
    Abstract: Methods and systems for double-sided semiconductor device fabrication. Devices having multiple leads on each surface can be fabricated using a high-temperature-resistant handle wafer and a medium-temperature-resistant handle wafer. Dopants can be introduced on both sides shortly before a single long high-temperature diffusion step diffuses all dopants to approximately equal depths on both sides. All high-temperature processing occurs with no handle wafer or with a high-temperature handle wafer attached. Once a medium-temperature handle wafer is attached, no high-temperature processing steps occur. High temperatures can be considered to be those which can result in damage to the device in the presence of aluminum-based metallizations.

  • Patent number: 9343559
    Abstract: Techniques are disclosed for customization of nanowire transistor devices to provide a diverse range of channel configurations and/or material systems within the same integrated circuit die. In accordance with one example embodiment, sacrificial fins are removed and replaced with custom material stacks of arbitrary composition and strain suitable for a given application. In one such case, each of a first set of the sacrificial fins is recessed or otherwise removed and replaced with a p-type layer stack, and each of a second set of the sacrificial fins is recessed or otherwise removed and replaced with an n-type layer stack. The p-type layer stack can be completely independent of the process for the n-type layer stack, and vice-versa. Numerous other circuit configurations and device variations are enabled using the techniques provided herein.
