    Abstract: The present invention discloses a method for manufacturing a low-temperature polysilicon thin film transistor and an array substrate, which is used for simplifying manufacturing process procedures of the thin film transistor. The method includes steps of: forming an a-Si layer on a substrate; forming an impurity film on the a-Si layer, positions of the impurity film corresponding to a source doping layer to be formed and a drain doping layer to be formed respectively; and converting the a-Si layer into a polysilicon layer, and during the conversion from the a-Si layer into the polysilicon layer, ions in the impurity film being implanted into regions in the polysilicon layer contacting with the impurity film to form the source doping layer and the drain doping layer. In particular, an excimer laser annealing process is performed on the a-Si layer and the impurity film, so that the source doping layer is formed in a region corresponding to the source doping layer to be formed, the drain doping layer is formed in a region corresponding to the drain doping layer to be formed and the polysilicon layer is formed in regions except the source doping layer and the drain doping layer.
