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 9):
The method for producing a pillar-shaped semiconductor device according to  claim 1 , wherein the first region of the first material layer includes a third region that is connected to the first impurity region and surrounds the first semiconductor pillar and a fourth region that surrounds an entire periphery of the first conductor layer so as to be in contact with the entire periphery of the first conductor layer,\n the second region of the first material layer includes a fifth region that is partly connected to the third region and extends in the horizontal direction and a sixth region that is partly connected to the fourth region and extends in the horizontal direction, and the fifth region and the sixth region are formed so as to be away from each other or to partly overlap each other in plan view.
