An atmospheric pressure plasma jet (APPJ) deposition technology that is employed for the preparation of transparent oxide semiconductors film using an eco‐friendly water‐based metal salt solution as a precursor is presented. Through the use of APPJ indium–gallium–zinc‐oxide (IGZO) film as the channe...
