Abstract:
A Metal Oxide Semiconductor Bipolar Junction Transistor comprising:a collector region comprised of a semiconductor material with a first type of dopant;an emitter region comprised of a semiconductor material with said first type of dopant;a base region disposed between said collector region and said emitter region, said base region being comprised of a semiconductor material with a second type of dopant that is opposite of said first type of dopant; anda base terminal comprised of a dielectric structure disposed over said base region and comprised of a gate structure disposed over said dielectric structure;wherein said dielectric structure is relatively thin such that a tunneling current through said dielectric structure results when a turn-on voltage is applied on said gate structure;and wherein said tunneling current is a base current of said Metal Oxide Semiconductor Bipolar Junction Transistor;and wherein said dielectric structure and said gate structure are not disposed over said collector region and said emitter region to prevent tunneling current between said gate structure and said collector and emitter regions.
