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 10):
The semiconductor device production method according to  claim 9 , wherein\n the trench etching is performed to provide a structure in which at least one of the first pattern portion and the second pattern portion has a heat escape portion that releases heat from the at least one pattern portion, so that both of the first pattern portion and the second pattern portion have the same temperature during the trench etching.
