The Research of Femtosecond Laser Process Flip-Chip LEDs for Upgrading Lighting Efficiency
碩士 === 國立中正大學 === 光機電整合工程研究所 === 101 === In this study, we use femtosecond laser to process on sapphire substrate, and identify the relationship between laser dose and the laser ablation width on sapphire substrate. We find that laser process can induce sapphire period surface structure data is 4mW...
