More Information
Summary:A light generation system is provided. The light generation system includes a vaporization device, a laser device and a lens structure. The vaporization device is configured to vaporize a metal-nonmetal compound to generate a metal-nonmetal precursor gas. The laser device is configured to provide laser light, and irradiate the metal-nonmetal precursor gas released from the vaporization device with the laser light to emit a light signal. The lens structure is configured to direct the light signal toward a photomask used in a lithography process.
