Claim Text:
1. A method for manufacturing a thin film transistor which comprising a base substrate, and a gate, an active layer, a source and a drain formed on the base substrate, wherein a material for the active layer is an amorphous phosphide semiconductor material, wherein the material of the active layer is InGaZnP, patterns of the active layer are prepared by means of magnetron sputtering, and the method comprises: depositing an InGaZnP thin film in an oxygen atmosphere at a pressure of 1 Pa-10 Pa; annealing the InGaZnP thin film for an hour in an air atmosphere at a temperature of 100° C-600° C.; and patterning the InGaZnP thin film and forming the patterns of the active layer.
