This monograph investigates novel technologies for metal-induced crystallization (MIC) and post-annealing processes to enhance the quality of polysilicon films for low-temperature polysilicon thin-film transistors (TFTs). The work addresses the limitations of amorphous silicon TFTs in flat panel displays by proposing low-temperature polysilicon as a superior alternative. It details advancements in MIC, including solution-based MIC (SMIC) and defined-grain MIC (DG-MIC), aimed at improving polysilicon film quality and TFT performance. Furthermore, it introduces innovative post-annealing techniques, such as YAG laser and flash lamp annealing, to reduce micro-defects and achieve better device characteristics, notably reporting for the first time the application of flash lamp annealing in this context.

This work presents a focused investigation into advanced fabrication techniques for polysilicon thin-film transistors, specifically detailing improvements in metal-induced crystallization and post-annealing processes.
