Patent ID: 8173992

Claim:
A microelectronic device comprising: a substrate; and at least one tunneling effect transistor or triode on said substrate, and comprising at least one first block on said substrate and defining an anode, at least one second block on said substrate and defining a cathode, at least one of said first and second blocks comprising at least one, stack of different layers of materials, with the at least one stack of different layers of materials comprising a plurality of conducting layers directly contacting one another so that an interface therebetween is devoid of an insulating layer, at least one channel insulating zone comprising a dielectric material on said substrate and contacting opposing sides of said at least one first and second blocks, at least one gate dielectric on said at least one channel insulating zone, and on an upper surface of said at least one first and second blocks, said at least one gate dielectric completely overlying said at least one channel insulating zone and partially overlying each conducting layer in each of said first and second blocks, at least one gate on said at least one gate dielectric, an insulating layer on said first and second blocks and on said at least one gate, a first conductive via in said insulating layer to define a first contact contacting said at least one first block, and a second conductive via in said insulating layer to define a second contact contacting said at least one second block.
