The present invention provides a TFT substrate structure and a manufacturing method thereof. A metal oxide semiconductor layer is formed on an amorphous silicon layer to replace an N-type heavily-doped layer. The potential barrier between the amorphous silicon layer and metal layer is relatively low, making it possible to form an ohmic contact and thus increasing current efficiency, without the need of doping other ions to form the N-type heavily-doped layer. Further, the metal oxide semiconductor layer comprises numerous defects that trap holes so that during the operation of the TFT, even a great negative voltage is applied to the gate terminal to thus form a hole conducting channel, the holes may hardly move from the source/drain terminals through the metal oxide semiconductor layer and the semiconductor layer to reach the conducting channel and consequently, the current leakage issue occurring in a hole conducting zone of a conventional TFT substrate structure can be improved and severe bending of the hole current curve and poor reliability are also improved.
