Abstract:
An object is to manufacture a highly reliable semiconductor device including a thin film transistor with stable electric characteristics. In a method for manufacturing a semiconductor device including a thin film transistor in which an oxide semiconductor film is used for a semiconductor layer including a channel formation region, heat treatment (for dehydration or dehydrogenation) is performed to improve the purity of the oxide semiconductor film and reduce impurities including moisture or the like. After that, slow cooling is performed under an oxygen atmosphere. Besides impurities including moisture or the like exiting in the oxide semiconductor film, heat treatment causes reduction of impurities including moisture or the like exiting in a gate insulating layer and those in interfaces between the oxide semiconductor film and films which are provided over and below the oxide semiconductor and in contact therewith.

Claim (Index 1):
A method for manufacturing a semiconductor device comprising the steps of:\n forming an oxide semiconductor layer on an insulating layer; performing dehydration or dehydrogenation on the oxide semiconductor layer and then cooling the oxide semiconductor layer in an oxygen atmosphere; forming a source electrode layer and a drain electrode layer over the oxide semiconductor layer after dehydration or dehydrogenation have been performed on the oxide semiconductor layer; and forming an oxide insulating film over the insulating layer, the oxide semiconductor layer, the source electrode layer, and the drain electrode layer, and in contact with part of the oxide semiconductor layer.
