Claim:
1. A manufacturing method of an oxide semiconductor thin-film transistor (TFT) substrate, comprising the following steps: Step 1: providing a substrate and depositing and patternizing an oxide conductor layer on the substrate to form an oxide conductor layer having a channel; Step 2: depositing and patternizing an oxide semiconductor layer on the oxide conductor layer to form an oxide semiconductor layer; Step 3: depositing a first insulation layer on the oxide semiconductor layer; Step 4: depositing and patternizing a first metal layer on the first insulation layer to form a gate terminal; Step 5: depositing a second insulation layer on the gate terminal; Step 6: subjecting the first insulation layer and the second insulation layer simultaneously to a patternization operation to form vias; and Step 7: forming a source terminal and a drain terminal on the second insulation layer.
