We have reproduced columnar grains formed after laser crystallization from amorphous-Si to poly-Si in actual experiments using a crystallization simulator. The crystallization simulator possesses random nucleation, crystal growth velocity, latent heat emission, and partial crystallization models. The columnar grains appear by assuming partial melting condition where thin amorphous-Si remains underneath...
Thin-film transistors (TFTs) are key devices for high image quality information displays. Features and applications of various TFTs, such as matured amorphous and poly-Si TFTs and transparent poly-ZnO and amorphous InGaZnO TFTs, are discussed.
