发明名称 Method for fabricating low temperature poly-silicon thin film transistor substrate
摘要 An exemplary method for fabricating an LTPS-TFT substrate is as follows. In step S1, a p-Si pattern including a source electrode contact region and a drain electrode contact region of a first type TFT, a source electrode contact region and a drain electrode contact region of a second type TFT is formed. In step S2, the source electrode contact region and the drain electrode contact region of the first type TFT are heavily doped with a first dopant. In step S3, gate electrodes of the first and the second type TFT are formed. In step S4, the source electrode contact regions and drain electrode contact regions of the first and second type TFTs are heavily doped with a second dopant. The first dopant and the second dopant are compensative, and the number ratio of the first dopant to the second dopant is approximately 2 to 1.
