ABSTRACT:
The semiconductor device includes a substrate having a conductive layer formed on its surface. The conductive layer has a columnar semiconductor formed thereon. The columnar semiconductor has an insulating layer formed therearound. The insulating layer has an electrode film formed therearound. The electrode film functions as an gate electrode of a transistor. The electrode film includes an laminate of two or more conductive films having different work functions.
