  • Publication number: 20210398971
    Abstract: Examples of integrated semiconductor devices are described. In one example, an integrated device includes first and second transistors formed on a substrate, where the transistors share a terminal metal feature to reduce a size of the integrated device. The terminal metal feature can include a shared source electrode metalization, for example, although other electrode metalizations can be shared. In other aspects, a first width of a gate of the first transistor can be greater than a second width of a gate of the second transistor, and the shared metalization can taper from the first width to the second width. The integrated device can also include a metal ground plane on a backside of the substrate, and the terminal metal feature can also include an in-source via for the shared source electrode metalization. The in-source via can electrically couple the shared source electrode metalization to the metal ground plane.

  • Patent number: 11203398
    Abstract: A buoy (10) comprising a central column (12), an outer frame (14) attached to the central column with buoyancy which may be provided by the outer frame and/or by attached buoyancy units (16). The central column is negatively buoyant and is normally open at one end to allow water to flow in, and create an oscillating water column caused by waves. This water column dampens the effect of wave or other forces on the buoy, thus providing a more stable foundation for a wind powered generator. A further generator may be provided to extract energy from the oscillating water column. The buoy is normally attached to an anchor by one or more tension leg tethers which maintains the buoyancy below the surface of the water which has also be found to increase stability. The anchor may be a modular gravity base anchor.

  • Patent number: 11147260
    Abstract: A system for fumigating soil includes applying a fumigant film component and an underlying drip tape element to the soil to be treated. A non-tarp method can also be used through permanently buried drip tape (SDI) that is at least 8 inches deep and utilizes the soil above as the barrier to prevent the fumigant from escaping. The drip tape element is communicably connected through a throttle valve to a pressurized liquid supply of fumigant having a low boiling point and a high vapor pressure. The valve is opened to dispense vaporized fumigant into the soil and dissipation of the fumigant is controlled so that more effective soil fumigation is achieved.

  • Publication number: 20210303152
    Abstract: In some examples, an input device includes a non-linear component, such as a diode. In response to a drive signal, such as a sinusoidal wave, the non-linear passive input device can produce a non-linear output that includes frequency content at the second and other higher harmonics of the fundamental frequency of the drive signal, for example. In some examples, drive electrodes can be driven with a drive signal having one of two fundamental frequencies such that the frequency of the drive signals are applied in an alternating pattern. The electronic device can sense the signal of the stylus to determine the coarse location of the stylus along the sense electrodes and, based on the frequency content of the received signal, a fine location along the axis of the drive electrodes.

  • Publication number: 20210257195
    Abstract: A processing chamber such as a plasma etch chamber can perform deposition and etch operations, where byproducts of the deposition and etch operations can build up in a vacuum pump system fluidly coupled to the processing chamber. A vacuum pump system may have multiple roughing pumps so that etch gases can be diverted a roughing pump and deposition precursors can be diverted to another roughing pump. A divert line may route unused deposition precursors through a separate roughing pump. Deposition byproducts can be prevented from forming by incorporating one or more gas ejectors or venturi pumps at an outlet of a primary pump in a vacuum pump system. Cleaning operations, such as waferless automated cleaning operations, using certain clean chemistries may remove deposition byproducts before or after etch operations.
