    摘要: Device structures with a reduced junction area in an SOI process, methods of making the device structures, and design structures for a lateral diode. The device structure includes one or more dielectric regions, such as STI regions, positioned in the device region and intersecting the p-n junction between an anode and cathode. The dielectric regions, which may be formed using shallow trench isolation techniques, function to reduce the width of a p-n junction with respect to the width area of the cathode at a location spaced laterally from the p-n junction and the anode. The width difference and presence of the dielectric regions creates an asymmetrical diode structure. The volume of the device region occupied by the dielectric regions is minimized to preserve the volume of the cathode and anode.

    摘要: Disclosed are embodiments of a lateral, extended drain, metal oxide semiconductor, field effect transistor (LEDMOSFET) having tapered dielectric field plates positioned laterally between conductive field plates and opposing sides of a drain drift region of the LEDMOSFET. Each dielectric field plate comprises, in whole or in part, an airgap. These field plates form plate capacitors that can create an essentially uniform horizontal electric field profile within the drain drift region so that the LEDMOSFET can exhibit a specific, relatively high, breakdown voltage (Vb). Tapered dielectric field plates that incorporate airgaps provide for better control over the creation of the uniform horizontal electric field profile within the drain drift region, as compared to tapered dielectric field plates without such airgaps and, thereby ensure that the LEDMOSFET exhibits the specific, relatively high, Vb desired. Also disclosed herein are embodiments of a method of forming such an LEDMOSFET.
