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 13):
The method of  claim 12 , wherein forming the gate stack structure comprises:\n forming a P-type work function adjustment material layer on a portion of the gate dielectric material layer disposed on sidewalls of a corresponding semiconductor pillar on one of the device regions; forming an N-type work function adjustment material layer on the P-type work function adjustment material layer; forming a gate material layer on the gate dielectric layer and on the N-type work function adjustment layer; planarizing the gate material layer such that an upper surface of the gate material layer is flush with an upper surface of the gate dielectric material layer on the semiconductor column; etching the gate material layer, the P-type work function adjustment material layer, and the N-type work function adjustment material layer to expose a portion of the gate dielectric material layer on the upper surface and the sidewalls of the semiconductor column.
