Abstract: A method for manufacturing a semiconductor device comprises steps of: forming an oxide semiconductor layer on a substrate by a sputtering method; performing a first heat treatment on the oxide semiconductor layer after placing the substrate on which the oxide semiconductor layer is formed in a heating furnace having a heating medium maintained at a preset temperature; forming a gate insulating layer on the oxide semiconductor layer after the first heat treatment; and forming a gate electrode on the gate insulating layer. When the substrate is installed in the heating furnace, a temperature drop of the heating medium is kept within 15% of the set temperature.
