    摘要: An MOS-bipolar hybrid-mode LDMOS device has a main gate input and a control gate input wherein the device operates in an MOS mode when both gate inputs are enabled, and operates in a bipolar mode when the main gate input is enabled and the control gate input is disabled. The device can drive the gate of a power MOSFET to deliver the high current required by the power MOSFET while in the bipolar mode, and provide a fully switching between supply voltage and ground to the gate of the power MOSFET while in the MOS mode.

    摘要: A semiconductor device, such as a LDMOS device, comprising: a semiconductor substrate; a drain region in the semiconductor substrate; a source region in the semiconductor substrate laterally spaced from the drain region; and a drift region in the semiconductor substrate between the drain region and the source region. A gate is operatively coupled to the source region and is located offset from the drain region on a side of the source region opposite from the drain region. When the device is in an on state, current tends to flow deeper into the drift region to the offset gate, rather than near the device surface. The drift region preferably includes at least first and second stacked JFETs. The first and second stacked JFETs include first, second and third layers of a first conductivity type, a fourth layer intermediate the first and second layers including alternating pillars of the first conductivity type and of a second conductivity type extending between the source and drain regions; and a fifth layer intermediate the second and third layers, including alternating pillars of the first and second conductivity types extending between the source and drain regions.

    摘要: A lateral Insulated Gate Bipolar Transistor (LIGBT) includes a semiconductor substrate and an anode region in the semiconductor substrate. A cathode region of a first conductivity type in the substrate is laterally spaced from the anode region, and a cathode region of a second conductivity type in the substrate is located proximate to and on a side of the cathode region of the first conductivity type opposite from the anode region. A drift region in the semiconductor substrate extends between the anode region and the cathode region of the first conductivity type. An insulated gate is operatively coupled to the cathode region of the first conductivity type and is located on a side of the cathode region of the first conductivity type opposite from the anode region. An insulating spacer overlies the cathode region of the second conductivity type. The lateral dimensions of the insulating spacer and the cathode region of the second conductivity type are substantially equal and substantially smaller than the lateral dimension of the cathode region of the first conductivity type.
