Classification: CPC H | IPC H

Claim 5:
6. A ternary inverter device comprising:
an NMOS transistor device; and
a PMOS transistor device,
wherein each of the NMOS transistor device and the PMOS transistor device comprises:
a substrate;
a fin structure extending on the substrate in a direction parallel to a top surface of the substrate;
a source region and a drain region provided at an upper portion of the fin structure; and
a constant current generating layer provided under the fin structure,
wherein the constant current generating layer directly contacts a lower portion of the source region and a lower portion of the drain region, and generates a constant current between the drain region and the substrate,
the drain region of the NMOS transistor device and the drain region of the PMOS transistor device have identical voltages, and
in each of the NMOS transistor device and the PMOS transistor device, the substrate and the constant current generating layer have a conductivity type identical to each other, and the source region and the drain region have another conductivity type identical to each other, and an electric field is formed between the drain region and the constant current generating layer.
