摘要
Ciystallization of a-Si by overlap scan using CW Nd:YVO4 laser has been investigated with SEM, AFM, and Raman spectroscopy. The results show that the grains existing near each laser scan boundary meet together forming single grains. That means the width of grains formed by prior-scanning affects the width of the grains formed by the following scan. Thus, the overlap scanning method can be applied to large grained poly-Si fabrication for LTPS processing.
