A Study on Optimization of Megasonic Cleaning Process for Manufacturing LCD

  • 발행 : 2001.10.01

초록

Recently, TFT LCD (thin film transistor liquid crystal display) manufacturing industry is more concerned with the ways of cleaning large TFT LCD´s with high pixed density than ever Ultrasonic cleaners with high frequencies like 1MHz (megasonic cleaners) are effective in removing very small particles without causing mechanical damage to the surface. In this study a megasonic cleaner for TFT LCD manufacturing process is developed and the performance is evaluated through experiments. The experimental results show that the developed magasonic cleaners is effective in removing very small particle from the LCD panel.
