Abstract:
A manufacturing method of TFT substrate and a TFT substrate are provided. The method provides a dual-gate structure symmetrically disposed on both sides of active layer, which prevents TFT threshold voltage from changing and improve TFT conduction state switching; by first manufacturing the active layer before the gate insulating layer to make the insulating layer directly grow on active layer, the contact interface between the gate insulating layer and active layer is improved, leading to further improving TFT conduction state switching. The TFT substrate makes the gate located between the source and the pixel electrode in vertical direction, and the dual-gate is symmetrically disposed on both sides of active layer to prevent TFT threshold voltage from changing and improve TFT conduction state switching, as well as improve the contact interface between the gate insulating layer and active layer, leading to further improving TFT conduction state switching.

Claim (Index 2):
The manufacturing method of TFT substrate as claimed in  claim 1 , wherein Step  1  further comprises: depositing a first metal layer on the base substrate by physical vapor deposition, and using a lithography process to patternize the first metal layer to obtain the data line and the source connected to the data line; the lithography process comprising:\n photo-resist coating, exposure, development, and wet etching process; \n Step  2  further comprises: depositing a semiconductor layer on the base substrate, data line and source by chemical or physical vapor deposition, and using a lithography process to patternize the semiconductor layer to obtain the active layer; the lithography process comprising: photo-resist coating, exposure, development, and wet etching process; \n the data line and the source are made of one or more of the following: \n molybdenum, titanium, aluminum, copper; and \n the active layer is made of amorphous silicon, polysilicon, or a metal oxide semiconductor.
