Abstract:
A semiconductor-on-insulator (SOI) inverter circuit, comprising:a bulk substrate; an insulator layer formed on a surface of the substrate; an active semiconductor layer formed on a surface of the insulator layer opposite the substrate; a p-type body region and an n-type body region formed generally adjacent one another in the active semiconductor layer; an n-channel metal-on-semiconductor field effect transistor (MOSFET) formed in the p-type body region and a p-channel MOSFET formed 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; a p-type body tie region formed in the active semiconductor layer immediately adjacent the p-type body region and an n-type body tie region formed in the active semiconductor layer immediately adjacent the n-type body region; and an electrically conductive element electrically coupling the p-type body tie region to the n-type body tie region.
