Abstract
A method of forming a bulk transistor integrated with silicon-on-insulator (SOI) field plates, and related device, are provided. Embodiments include forming a silicon-on-insulator (SOI) substrate as a field plate on a field plate oxide; forming a high-voltage p-type well in a p-type substrate of a bulk transistor on which the SOI substrate is formed, the high-voltage p-type formed between shallow trench isolation (STI) region of the p-type substrate; forming an n-drift region in the high-voltage p-type well; forming a first gate on the high-voltage p-type well; and implanting a first n-type region adjacent to the gate as a source region and a second n-type region adjacent to the SOI substrate as a drain region.
