Abstract:
The method for producing a pillar-shaped semiconductor device includes a step of providing a structure that includes, on an i layer substrate, a Si pillar and an impurity region located in a lower portion of the Si pillar and serving as a source or a drain, a step of forming a SiO 2  layer that extends in a horizontal direction and is connected to an entire periphery of the impurity region in plan view, a step of forming a SiO 2  layer on the SiO 2  layer such that the SiO 2  layer surrounds the Si pillar in plan view, a step of forming a resist layer that is partly connected to the SiO 2  layer in plan view, and a step of forming a SiO 2  layer by etching the SiO 2  layer below the SiO 2  layer and the resist layer using the SiO 2  layer and the resist layer as masks.

Claim (Index 15):
The method for producing a pillar-shaped semiconductor device according to  claim 14 , wherein the second material layer and the seventh material layer are formed in a connected manner between the first semiconductor pillar and the second semiconductor pillar in plan view, the method further comprising a step of etching the first material layer using the second material layer and the seventh material layer as masks.
