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 20):
The method for producing a semiconductor device including an SGT according to  claim 19 , the method further comprising:\n a step of forming fourth material layers that surround peripheries of the first semiconductor pillar and the second semiconductor pillar and are connected to each other in a portion between the first semiconductor pillar and the second semiconductor pillar; and a step of etching the first conductive layer using the fourth material layer as an etching mask to form a ninth conductive layer that surrounds an entire periphery of the first impurity region or the first gate conductor layer with an equal width in plan view, a tenth conductive layer that surrounds an entire periphery of the second impurity region or the second gate conductor layer with an equal width, an eleventh conductive layer that is partly connected to peripheries of the ninth conductive layer and the tenth conductive layer and extends in parallel with a surface of the substrate, and a twelfth conductive layer that is partly in contact with peripheries of the ninth conductive layer and the tenth conductive layer in plan view and has an equal width in plan view.
