초록
For AMLCD pixel switching device, poly-Si TFT has the advantage of high field effect mobility over a-Si TFT. However, it also has some disadvantage such as large leakage current and more masking steps. We propose a new Inverse Staggered poly-Si TFT with a-Si offset. We have fabricated the new device and verified high ON/OFF current ratio. The device has lower leakage current level than the conventional Inverse Staggered poly-Si TFT and the same number of masking steps compared with conventional a-Si TFT's.
