Abstract

AbstractThe amorphous silicon thin transistor (a-Si TIFT) has successfully industrialized the active matrix liquid crystal displays (AMLCDs), which would get a vast market on the basis of their wide potential use for displays. Whereas, the polysilicon TFT (p-Si TFT) also has been intensely investigated and intended to realize smarter AMLCDs, with monolithic peripheral circuits.In this paper, we will discuss the applicable range of low temperature p-Si TFTs compared with high temperature p-Si TFTs. After reviewing the materials which comprise low temperature p-Si TFTs, we will introduce our self aligned aluminum gate process which could allow fast addressing even in enlarged AMLCDs in the future.
