Abstract
Shallow trench isolation silicon-on-insulator (SOI) devices are formed with improved charge protection. Embodiments include an SOI film diode and a Psubstrate junction as a charging protection device. Embodiments also include a conductive path from the SOI transistor drain, through a conductive contact, a metal line, a second conductive contact, an SOI diode, isolated from the transistor, a third conductive contact, a second conductive line, and a fourth conductive contact to a P-doped substrate contact in the bulk silicon layer of the SOI substrate.
