We investigated In‐Ga‐Zn oxide films deposited by two types of sputtering methods: planar magnetron and facing‐target. In crystallinity, we found that silicon diffused from SiO x prevents crystallization regardless of the sputtering method. In electrical property, we found that mobility of films deposited by facing‐target sputtering less depends on carrier concentration.
