Abstract:
An SGT is formed in Si pillars. The SGT includes WSi 2  layers serving as wiring alloy layers and constituted by first alloy regions that are connected to the entire peripheries of impurity regions serving as sources or drains located in lower portions of the Si pillars, are formed in a self-aligned manner with the impurity regions in a tubular shape, and contain the same impurity atom as the impurity regions and a second alloy region that is partly connected to the peripheries of the first alloy regions and contains the same impurity atom as the impurity regions.

Claim (Index 19):
The method for producing a semiconductor device including an SGT according to  claim 18 , the method comprising:\n a step of forming a second semiconductor pillar that is adjacent to the first semiconductor pillar; a step of forming a second gate insulating layer that surrounds the second semiconductor pillar and has the same height as the first gate insulating layer in the vertical direction; a step of forming a second gate conductor layer that surrounds the second gate insulating layer; a step of forming, around the second semiconductor pillar, a second impurity region that has the same height as the first impurity region in the vertical direction and contains a donor or acceptor impurity; a step of forming a seventh conductive layer that is in contact with the second impurity region in plan view; and a step of forming an eighth conductive layer that is in contact with the second gate conductor layer in plan view, wherein at least one of the seventh conductive layer and the eighth conductive layer has an equal width in plan view, the fifth conductive layer and the seventh conductive layer are formed so as to be connected to each other on the same plane, and the sixth conductive layer and the eighth conductive layer are formed so as to be connected to each other on the same plane.
