Abstract:
A method of manufacturing a semiconductor-on-insulator (SOI) inverter circuit, comprising:forming an insulator layer on a surface of a bulk substrate; forming an active semiconductor layer on a surface of the insulator layer opposite the substrate; forming a p-type body region and an n-type body region generally adjacent one another in the active semiconductor layer; forming an n-channel metal-oxide-semiconductor field effect transistor (MOSFET) in the p-type body region and a p-channel MOSFET in the n-type body region, wherein a gate of each of the n-channel MOSFET and the p-channel MOSFET are electrically coupled to form an input of the inverter circuit and a drain of each of the n-channel MOSFET and the p-channel MOSFET are electrically coupled to form an output of the inverter; forming a p-type body tie region in the active semiconductor layer immediately adjacent the p-type body region and an n-type body tie region in the active semiconductor layer immediately adjacent the n-type body region; and providing an electrically conductive element electrically coupling the p-type body tie region to the n-type body tie region.
