Abstract

An embodiment is a semiconductor device comprising a receiver circuit comprising fin field effect transistors (FinFETs), a transceiver circuit comprising FinFETs, and a transmit bus electrically coupling the receiver circuit and the transceiver circuit, wherein the receiver circuit and the transceiver circuit each further comprises an electrostatic discharge protection circuit comprising planar transistors electrically coupled to the transmit bus. Other embodiments may further comprise a power clamp electrically coupling a first power bus and a first ground bus, a power clamp electrically coupling a second power bus and a second ground bus, or at least two diodes electrically cross-coupling the first ground bus and the second ground bus. Also, the planar transistors of the transceiver circuit and the receiver circuit may each comprise a planar PMOS transistor and a planar NMOS transistor.
