Abstract

A well-known major problem in thin-film transistor (TFT) manufacturing is the protrusions that form on low-temperature polysilicon thin films after excimer laser annealing, which, in turn, induce gate leakage current in the TFTs. In this paper, we report the use of additional laser irradiation to reduce the height of protrusions.
