A lightly-doped region of the first conductivity type is under and vertically overlaps the anode and the first and the second cathodes. The portion of the lightly-doped region directly under the second cathode is fully depleted at a state when no bias voltage is applied between the anode and the second cathode.

    摘要: To limit or prevent current crowding, various HV-MOSFET embodiments include a current diversion region disposed near a drain region of an HV-MOSFET and near an upper surface of the semiconductor substrate. In some embodiments, the current diversion region is disposed near a field plate of the HV-MOSFET, wherein the field plate can also help to reduce or “smooth” electric fields near the drain to help limit current crowding. In some embodiments, the current diversion region is a p-doped, n-doped, or intrinsic region that is at a floating voltage potential. This current diversion region can push current deeper into the substrate of the HV-MOSFET (relative to conventional HV-MOSFETs), thereby reducing current crowding during ESD events. By reducing current crowding, the current diversion region makes the HV-MOSFETs disclosed herein more impervious to ESD events and, therefore, more reliable in real-world applications.

    摘要翻译: 为了限制或防止电流拥挤,各种HV-MOSFET实施例包括设置在HV-MOSFET的漏极区附近并且在半导体衬底的上表面附近的电流分流区域。 在一些实施例中,电流引流区域设置在HV-MOSFET的场板附近,其中场板还可以帮助减少或“平滑”漏极附近的电场,以帮助限制电流拥挤。 在一些实施例中,电流分流区域是处于浮置电压电位的p掺杂,n掺杂或本征区域。 该电流分流区可以将电流深度推入HV-MOSFET的衬底(相对于传统HV-MOSFET),从而减少ESD事件期间的电流拥挤。 通过减少电流拥挤,电流分流区域使得本文公开的HV-MOSFET更加不可避免地存在ESD事件,因此在现实世界的应用中更可靠。
