Abstract:
A semiconductor device includes a substrate, a semiconductor column vertically disposed on the substrate, a first contact material layer on the substrate and in contact with a lower portion of the semiconductor column, a first insulating material layer on the first contact material layer and having an upper surface lower than an upper surface of the semiconductor column, a gate dielectric material layer on the first insulating material layer and on a portion of sidewalls of the semiconductor column while exposing an upper portion of the semiconductor column, and a gate stack structure on the gate dielectric material layer and surrounding a portion of the gate dielectric material layer on the sidewalls of the semiconductor column. The gate stack structure includes from inside to outside a P-type work function layer, an N-type work function layer, and a gate.

Claim (Index 5):
The semiconductor device of  claim 2 , wherein:\n the first P-type work function layer comprises, sequentially from inside to outside, a first TiN layer, a TaN layer, a third TiN layer, a fourth TiN layer, and a fifth TiN layer; the second P-type work function layer comprises, sequentially from inside to outside, the first TiN layer, the TaN layer, the third TiN layer, and the fourth TiN layer; the third P-type work function layer comprises, sequentially from inside to outside, the fourth TiN layer and the fifth TiN layer; and the fourth P-type work function layer comprises the fifth TiN layer.
