Flash lamp annealing (FLA) has attracted attentions as a technique of rapidly crystallizing precursor a-Si films to form poly-Si films with high crystallinity on low-cost glass substrates. In this chapter, a brief explanation on fundamental physics typically seen in nonthermal equilibrium annealing and in utilization of metastable a-Si as precursor films have been given. Recent findings concerning FLA-triggered crystallization of micrometer-order-thick a-Si films and microstructures of the poly-Si films are also introduced.
