Abstract:
An object is to control composition and a defect of an oxide semiconductor, another object is to increase a field effect mobility of a thin film transistor and to obtain a sufficient on-off ratio with a reduced off current. A solution is to employ an oxide semiconductor whose composition is represented by InMO 3 (ZnO) m , where M is one or a plurality of elements selected from Ga, Fe, Ni, Mn, Co, and Al, and in is preferably a non-integer number of greater than or equal to 1 and less than 50. The concentration of Zn is lower than the concentrations of In and M. The oxide semiconductor has an amorphous structure. Oxide and nitride layers can be provided to prevent pollution and degradation of the oxide semiconductor.
