Abstract:
A semiconductor device production method includes performing trench etching to form a trench in a thickness direction of a semiconductor layer so that both of a first pattern portion and a second pattern portion whose side walls face each other across the trench are formed. In the trench etching, the semiconductor layer is etched and removed while a protective film is formed on a surface of the semiconductor layer, and the trench etching is performed so that the first pattern portion and the second pattern portion are configured to have a same potential or a same temperature during the trench etching.

Claim (Index 9):
The semiconductor device production method according to  claim 1 , wherein\n the trench etching is performed to provide a structure in which the first pattern portion and the second pattern portion have the same temperature during the trench etching.
