    Abstract: Disclosed is a manufacturing method of a complementary metal oxide semiconductor transistor, comprising a step of implementing a channel doping to an N-type channel region. The step comprises: preparing a low temperature polysilicon layer on a substrate, and patterning the low temperature polysilicon layer to form the N-type channel region correspondingly above a light shielding pattern; coating a negative photoresist on the substrate, and using the light shielding pattern as a mask to implement exposure to the negative photoresist from a back surface of the substrate to form a negative photoresist mask plate exposing the N-type channel region after development; implementing the channel doping to the N-type channel region with shielding of the negative photoresist mask plate. Further disclosed is a manufacturing method of an array substrate, applied with the aforesaid manufacturing method of the complementary metal oxide semiconductor transistor.

    Abstract: The present invention provides a manufacturing method of LTPS array substrate, wherein the LTPS array substrate contains at least a metal mask layer, a buffer layer, an active layer, a gate insulating layer and a gate layer. The manufacturing method is to form the gate layer by patterning the gate layer using the metal mask layer as a photomask, and a width of the formed gate layer is smaller than a width of the metal mask layer so that a vertical projection of the gate layer falls within the scope of the metal mask layer. In the present invention, the cost of producing a metal mask for the gate electrode is saved by patterning the gate layer using the metal mask layer as a photomask, so that the cost of producing LTPS is saved and the process of production is simplified.
