FIELD EFFECT TRANISTOR USING AMORPHOUS OXIDE FILM AS CHANNEL LAYER, MANUFACTURING METHOD OF FIELD EFFECT TRANSISTOR USING AMORPHOUS OXIDE FILM AS CHANNEL LAYER, AND MANUFACTURING METHOD OF AMORPHOUS OXIDE FILM
An amorphous oxide containing hydrogen (or deuterium) is applied to a channel layer of a transistor. Accordingly, a thin film transistor having superior TFT properties can be realized, the superior TFT properties including a small hysteresis, normally OFF operation, a high ON/OFF ratio, a high saturated current, and the like. Furthermore, as a method for manufacturing a channel layer made of an amorphous oxide, film formation is performed in an atmosphere containing a hydrogen gas and an oxygen gas, so that the carrier concentration of the amorphous oxide can be controlled.
