Title: Semiconductor device
IPC: H01L27/1156
Filed: 2022-02-15
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device having a transistor using a highly reliable oxide semiconductor by solving a problem in which a transistor using an oxide semiconductor may be inferior in reliability to a transistor using an amorphous silicon. 
     SOLUTION: Impurities such as hydrogen, nitrogen, and carbon contained in an oxide semiconductor film are factors that deteriorate the semiconductor characteristics of the oxide semiconductor film. For example, hydrogen and nitrogen contained in the oxide semiconductor film cause a factor that shifts a threshold voltage of a transistor using the oxide semiconductor film in the negative direction. Further, nitrogen, carbon, and rare gas contained in the oxide semiconductor film inhibit the generation of a crystal region in the oxide semiconductor film. Therefore, a transistor having high reliability is manufactured by reducing the impurity concentration of the oxide semiconductor film.
