Abstract
A method to fabricate the TFT of a flat panel display. The method includes four photo etching processes and a back-exposure step. The gate is formed by the first photo etching process. The source and the drain are formed by the second photo etching process. Next, the back-exposure step is performed from the back of the substrate to form an island structure. Then, a protect layer is formed by the third photo etching process. Finally, the pixel electrode is formed by the fourth photo etching process.
