Claim Text:
1. A low temperature poly-silicon thin film preparation apparatus, comprising: a substrate cleaning tank for cleaning a glass substrate, a conveying means for conveying the glass substrate being disposed within the substrate cleaning tank; an ozone generating means for generating ozone; a gas delivery tube, comprising an input terminal and an output terminal, the input terminal being connected to the ozone generating means, the output terminal being connected to the substrate cleaning tank at an upper portion of the glass substrate within the substrate cleaning tank; the output terminal of the gas delivery tube being provided with an air knife, the air knife comprising an air knife gas inlet port and an air knife gas outlet port, the air knife gas outlet port being disposed parallel to the glass substrate, in order to blow the ozone onto a surface of the glass substrate uniformly; wherein, after the glass substrate is cleaned in the substrate cleaning tank, the gas delivery tube delivers the ozone generated by the ozone generating means to the substrate cleaning tank, in order to the blow the ozone onto the surface of the cleaned glass substrate; a laser annealing means for processing a laser annealing treatment to the glass substrate, in order to form a low temperature poly-silicon thin film on the surface of the glass substrate.
