Abstract:
The present disclosure provides a method for manufacturing an LTPS thin film transistor which includes: forming a light shielding pattern and an active layer of the LTPS thin film transistor on a base substrate through one single patterning process, in which an orthogonal projection of the active layer on the base substrate falls within an orthogonal projection of the light shielding pattern on the base substrate, and the light shielding pattern is made of a semiconductor material.

Claim (Index 4):
The method according to  claim 3 , wherein the forming the light shielding pattern and the active layer of the LTPS thin film transistor on the base substrate through the one single patterning process comprises:\n forming a first buffer layer on the base substrate; forming a heavily doped amorphous silicon layer on the first buffer layer; forming a second buffer layer on the heavily doped amorphous silicon layer; forming a polysilicon layer on the second buffer layer; coating a photoresist on the polysilicon layer and exposing the photoresist to form a photoresist-removed area and a photoresist-reserved area, and removing the heavily doped amorphous silicon layer, the second buffer layer and the polysilicon layer at the photoresist-removed area, to form the light shielding pattern by the heavily doped amorphous silicon layer at the photoresist-reserved area and form the active layer by the polysilicon layer at the photoresist-reserved area; and peeling off the photoresist at the photoresist-reserved area.
