    摘要: Semiconductor device structures and related fabrication methods are provided. An exemplary semiconductor device structure includes a body well region having a first conductivity type, a drift region and a source region each having a second conductivity type, where a channel portion of the body well region resides laterally between the source region and a first portion of the drift region that is adjacent to the channel portion. A gate structure overlies the channel portion and the adjacent portion of the drift region. A portion of the gate structure overlying the channel portion proximate the source region has the second conductivity type. Another portion of the gate structure that overlies the adjacent portion of the drift region has a different doping, and overlaps at least a portion of the channel portion, with the threshold voltage associated with the gate structure being influenced by the amount of overlap.

    摘要: Embodiments of semiconductor devices and driver circuits include a semiconductor substrate having a first conductivity type, an isolation structure (including a sinker region and a buried layer), an active device within a portion of the substrate contained by the isolation structure, and a resistor circuit. The buried layer is positioned below the top substrate surface, and has a second conductivity type. The sinker region extends between the top substrate surface and the buried layer, and has the second conductivity type. The active device includes a body region, which is separated from the isolation structure by a portion of the semiconductor substrate having the first conductivity type. The resistor circuit is connected between the isolation structure and the body region. The resistor circuit may include one or more resistor networks and, optionally, a Schottky diode and/or one or more PN diode(s) in series and/or parallel with the resistor network(s).

    摘要: A tunable antifuse element (102, 202, 204, 504, 952) includes a substrate material (101) having an active area (106) formed in a surface, a gate electrode (104) having at least a portion positioned above the active area (106), and a dielectric layer (110) disposed between the gate electrode (104) and the active area (106). The dielectric layer (110) includes a tunable stepped structure (127). During operation, a voltage applied between the gate electrode (104) and the active area (106) creates a current path through the dielectric layer (110) and a rupture of the dielectric layer (110) in a rupture region (130). The dielectric layer (110) is tunable by varying the stepped layer thicknesses and the geometry of the layer.
