We demonstrated as-grown crystalline InGaZnO (c-IGZO) thin film by spray pyrolysis at a substrate temperature of 425 °C without any subsequent crystallization process. The fabricated c-IGZO TFT exhibited high field-effect mobility of 44.93 cm2/Vs and excellent stability under positive bias temperature stress. Therefore, c-IGZO TFTs produced by spray pyrolysis are promising for low-cost, high-resolution display applications.
