Publication number: 20230189422Abstract: An extreme ultraviolet (EUV) photolithography system generates EUV light by irradiating droplets with a laser. The system includes a droplet generator with a nozzle and a piezoelectric structure coupled to the nozzle. The generator outputs groups of droplets. A control system applies a voltage waveform to the piezoelectric structure while the nozzle outputs the group of droplets. The waveform causes the droplets of the group to have a spread of velocities that results in the droplets coalescing into a single droplet prior to being irradiated by the laser.Type: ApplicationFiled: December 12, 2022Publication date: June 15, 2023Inventors: Yu-Kuang SUN, Cheng-Hao LAI, Yu-Huan CHEN, Wei-Shin CHENG, Ming-Hsun TSAI, Hsin-Feng CHEN, Chiao-Hua CHENG, Cheng-Hsuan WU, Yu-Fa LO, Shang-Chieh CHIEN, Li-Jui CHEN, Heng-Hsin LIU
