  • Patent number: 11929426
    Abstract: A semiconductor device with high reliability is provided. The present invention relates to a method for manufacturing a transistor including an oxide semiconductor. A stacked-layer structure of an oxide semiconductor and an insulator functioning as a gate insulator is subjected to microwave-excited plasma treatment, whereby the carrier concentration of the oxide semiconductor is reduced and the barrier property of the gate insulator is improved. In addition, a conductor functioning as an electrode and the insulator functioning as a gate insulator are formed in contact with the oxide semiconductor and then the microwave-excited plasma treatment is performed, whereby a high-resistance region and a low-resistance region can be formed in the oxide semiconductor in a self-aligned manner. Moreover, the microwave-excited plasma treatment is performed under an atmosphere containing oxygen with a high pressure, whereby a transistor having favorable electrical characteristics can be provided.
