    摘要: Provided is a high voltage semiconductor device. The high voltage semiconductor device includes a transistor having a gate, a source, and a drain. The source and the drain are formed in a doped substrate and are separated by a drift region of the substrate. The gate is formed over the drift region and between the source and the drain. The transistor is configured to handle high voltage conditions that are at least a few hundred volts. The high voltage semiconductor device includes a dielectric structure formed between the source and the drain of the transistor. The dielectric structure protrudes into and out of the substrate. Different parts of the dielectric structure have uneven thicknesses. The high voltage semiconductor device includes a resistor formed over the dielectric structure. The resistor has a plurality of winding segments that are substantially evenly spaced apart.
