Abstract: Some embodiments relate to a method. A semiconductor substrate is provided and has a base region and a crown structure extending upwardly from the base region. A plurality of fins are formed to extend upwardly from an upper surface of the crown structure. A gate dielectric material is formed over upper surfaces and sidewalls of the plurality of the fins. A conductive electrode material is formed over upper surfaces and sidewalls of the gate dielectric material. An etch is performed to etch back the conductive electrode material so upper surfaces of etched back conductive electrodes reside below the upper surfaces of the plurality of fins.

Abstract: Some embodiments relate to a two transistor band gap reference circuit. A first transistor includes a first source, a first drain, a first body region separating the first source from the first drain, and a first gate. The first drain and first gate are coupled to a DC supply terminal. The second transistor includes a second source, a second drain, a second body region separating the second source from the second drain, and a second gate. The second gate is coupled to the DC supply terminal, and the second drain is coupled to the first source. Body bias circuitry is configured to apply a body bias voltage to at least one of the first and second body regions. Other embodiments relate to FinFET devices.

Abstract: Some embodiments relate to a device disposed on a semiconductor substrate. The semiconductor substrate includes a base region and a crown structure extending upwardly from the base region. The crown structure is narrower than the base region. A plurality of fins extend upwardly from an upper surface of the crown structure. A gate dielectric material is disposed over upper surfaces and sidewalls of the plurality of the fins. A conductive electrode is disposed along sidewall portions of the gate dielectric material. An uppermost surface of the conductive electrode resides below the upper surfaces of the plurality of fins.

Abstract: A method includes receiving a first voltage at a first input circuit of a bi-directional charge pump circuit, selectively turning on a first switch of a switching circuit that is coupled electrically to a deep N-well transistor of a first set of one or more intermediate pump stages that are coupled between the first input circuit and a first output circuit, and providing a third voltage from the first output circuit in response to receiving a second voltage at an input of a first diode of the output circuit from the first set of the one or more intermediate pump stages.
