Abstract:
In a manufacturing process of a transistor including an oxide semiconductor film, oxygen doping treatment is performed on the oxide semiconductor film, and then heat treatment is performed on the oxide semiconductor film and an aluminum oxide film provided over the oxide semiconductor film. Consequently, an oxide semiconductor film which includes a region containing more oxygen than a stoichiometric composition is formed. The transistor formed using the oxide semiconductor film can have high reliability because the amount of change in the threshold voltage of the transistor by a bias-temperature stress test (BT test) is reduced.

Claim (Index 9):
The method according to  claim 2 , wherein the second heat treatment is performed in a third atmosphere comprising at least one of nitrogen, oxygen, and a rare gas, and wherein impurity concentration in the third atmosphere is lower than or equal to 1 ppm.
