Abstract:
A method for producing a pillar-shaped semiconductor device includes forming, above a NiSi layer serving as a lower wiring conductor layer and connecting to an N +  layer of an SGT formed within a Si pillar, a first conductor W layer that extends through a NiSi layer serving as an upper wiring conductor layer and connecting to a gate TiN layer and that extends through a NiSi layer serving as an intermediate wiring conductor layer and connecting to an N +  layer; forming an insulating SiO 2  layer between the NiSi layer and the W layer; and forming a second conductor W layer so as to surround the W layer and have its bottom at the upper surface layer of the NiSi layer, to achieve connection between the NiSi layer and the NiSi layer.

Claim (Index 6):
The method for producing a pillar-shaped semiconductor device according to  claim 1 , wherein at least any one of the first wiring conductor layer, the second wiring conductor layer, and the third wiring conductor layer has a single-crystal semiconductor layer that connects to the side surface of the at least one semiconductor pillar and that contains acceptor or donor impurity.
