In a fixed channel width and length of different channels, the results from the experiments show: Y 6% doped and Y 12% doped indium oxide thin-film transistor with 300 nm to 50 nm channel length, the drain current is gradually increased, mobility is increased from 5.78 cm2/Vs to 10.07 cm2/Vs (Y 6%), 1.19 cm2/Vs increased to 1.69 cm2/Vs (Y 12%), and On-Off ratio and 104 (Y 6%) and 105 (Y 12%). In the SU-8 passivation layer, we obtain higher drain current with SU-8 passivation layer, and mobility increased from 1.04 cm2/Vs to 2.08 cm2/Vs, but On-Off ratio is maintained at 105.
