Abstract

An extreme ultraviolet (EUV) photolithography system generates EUV light by irradiating droplets with a laser. The system includes a collector and a plurality of vibration sensors coupled to the collector. The vibration sensors generate sensor signals indicative of shockwaves from laser pulses and impacts from debris. The system utilizes the sensor signals to improve the quality of EUV light generation.
