  • Patent number: 9601613
    Abstract: In one embodiment, a transistor includes a pillar of semiconductor material arranged in a racetrack-shaped layout having a substantially linear section that extends in a first lateral direction and rounded sections at each end of the substantially linear section. First and second dielectric regions are disposed on opposite sides of the pillar. First and second field plates are respectively disposed in the first and second dielectric regions. First and second gate members respectively disposed in the first and second dielectric regions are separated from the pillar by a gate oxide having a first thickness in the substantially linear section. The gate oxide being substantially thicker at the rounded sections. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.

  • Patent number: 9112017
    Abstract: A semiconductor device includes an N type well region in a P type substrate. A source region of a MOSFET is laterally separated from a boundary of the well region, which includes the drain of the MOSFET. An insulated gate of the MOSFET extends laterally from the source region to at least just past the boundary of the well region. A polysilicon layer, which forms a first plate of a capacitive anti-fuse, is insulated from an area of the well region, which forms the second plate of the anti-fuse. The anti-fuse is programmed by application of a voltage across the first and second capacitive plates sufficient to destroy at least a portion of the second dielectric layer, thereby electrically shorting the polysilicon layer to the drain of the HVFET.

  • Patent number: 8816433
    Abstract: In one embodiment, a transistor fabricated on a semiconductor die includes a first section of transistor segments disposed in a first area of the semiconductor die, and a second section of transistor segments disposed in a second area of the semiconductor die adjacent the first area. Each of the transistor segments in the first and second sections includes a pillar of a semiconductor material that extends in a vertical direction. First and second dielectric regions are disposed on opposite sides of the pillar. First and second field plates are respectively disposed in the first and second dielectric regions. Outer field plates of transistor segments adjoining first and second sections are either separated or partially merged.

  • Patent number: 8653583
    Abstract: In one embodiment, a semiconductor device includes a main vertical field-effect transistor (FET) and a sensing FET. The main vertical FET and the sense FET are both formed on a pillar of semiconductor material. Both share an extended drain region formed in the pillar above the substrate, and first and second gate members formed in a dielectric on opposite sides of the pillar. The source regions of the main vertical FET and the sensing FET are separated and electrically isolated in a first lateral direction. In operation, the sensing FET samples a small portion of a current that flows in the main vertical FET. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.

  • Publication number: 20130234243
    Abstract: In one embodiment, a transistor fabricated on a semiconductor die is arranged into sections of elongated transistor segments. The sections are arranged in rows and columns substantially across the semiconductor die. Adjacent sections in a row or a column are oriented such that the length of the transistor segments in a first one of the adjacent sections extends in a first direction, and the length of the transistor segments in a second one of the adjacent sections extends in a second direction, the first direction being substantially orthogonal to the second direction.
