¡A word of caution in manufacturing of oxide TFT with flexible substrate
Case of using flexible substrate with film shape
Oxide TFT and device are manufactured on original substrate, and then transferred to plastic film
Resin is coated on support substrate and cured, and then, oxide TFT and device are manufactured on resin film, finally, support substrate is released (The resin film is used as substrate.
