Abstract:
1. A thin film transistor structure disposed on a substrate, the thin film transistor structure comprising: a metal oxide semiconductor layer having a crystalline surface, wherein the crystalline surface is constituted by a plurality of grains separated from one another, and an indium content of the grains accounts for at least 50% of all metal elements of the metal oxide semiconductor layer; a gate disposed on one side of the metal oxide semiconductor layer; a source and a drain disposed on the other side of the metal oxide semiconductor layer; a gate insulation layer disposed between the gate and the metal oxide semiconductor layer; and a passivation layer disposed on the gate insulation layer, wherein the crystalline surface of the metal oxide semiconductor layer is in direct contact with the gate insulation layer or the passivation layer, and a material of the gate insulation layer and a material of the passivation layer comprise silicon oxide, silicon nitride, or silicon oxynitride.
