In this study we investigated post ELA(Excimer Laser Annealing) effect on SMC (Silicide Mediated Crystalization) poly-Si (Polycrystalline Silicon) to improve the characteristics of poly-Si. Combining SMC and XeCl ELA were used to crystallize the a-Si (amorphous Silicon) at various ELA energy density for LTPS (Low Temperature Polycrystalline Silicon). We fabricated the conventional SMC poly-Si with no SPC (Solid Phase Crystallization) phase using UV heating method[1] and irradiated excimer laser on SMC poly-Si, so called SMC-ELA poly-Si. After using post ELA we can get better surface morphology than conventional ELA poly-Si and enhance characteristics of SMC poly-Si. We also observed the threshold energy density regime in SMC-ELA poly-Si like conventional ELA poly-Si.
