Abstract:
The invention provides a BCE TFT substrate and manufacturing method thereof. The manufacturing method of BCE TFT substrate of the invention uses C-axis crystallized IGZO thin film to fabricate the active layer. Because the C-axis crystallized IGZO has extremely high corrosion resistance and is resistant to the erosion of the copper etchant, the active layer is not damaged in the source/drain etching process, and the performance of the active layer is stable. The manufactured BCE TFT substrate has stable electric performance. The amorphous IGZO thin film for fabricating the C-axis crystallized IGZO thin film is prepared under high oxygen atmosphere, so that the crystallization annealing temperature of the amorphous IGZO thin film is reduced to 600° C. or below. A high-temperature annealing furnace is saved and the production cost reduced. The BCE TFT substrate of the invention manufactured by the above method has stable electric performance and low production cost.

Claim (Index 6):
A back-channel-etched (BCE) thin film transistor (TFT) substrate, comprising: a base substrate, a gate disposed on the base substrate, a gate insulating layer disposed on the gate and the base substrate, an active layer disposed on the gate insulating layer, and a source and a drain separated with interval on the active layer; wherein the active layer being a C-axis crystallized IGZO thin film.
