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 14):
The method for producing a pillar-shaped semiconductor device according to  claim 1 , the method comprising:\n a step of forming a second semiconductor pillar that is adjacent to the first semiconductor pillar; a step of forming, on the first material layer, a seventh material layer that surrounds the second semiconductor pillar in plan view; a step of forming the third material layer that is partly connected to each of the second material layer and the seventh material layer in plan view; and a step of etching the first material layer using the second material layer, the third material layer, and the seventh material layer as masks, wherein the first region of the first material layer that surrounds the first semiconductor pillar in plan view is formed below the second material layer, a seventh region of the first material layer that surrounds the second semiconductor pillar in plan view is formed below the seventh material layer, and the second region of the first material layer that is partly connected to each of the first region and the seventh region in plan view is formed below the third material layer.
