  • Patent number: 10969691
    Abstract: Extreme ultraviolet (EUV) exposure apparatuses and methods, and methods of manufacturing a semiconductor device by using the exposure method, which minimize an error caused by a mirror in an EUV exposure process to improve an overlay error, are provided. The EUV exposure apparatus includes an EUV source configured to generate and output EUV, first illumination optics configured to transfer the EUV to an EUV mask, projection optics configured to project the EUV, reflected from the EUV mask, onto an exposure target, a laser source configured to generate and output a laser beam for heating, and second illumination optics configured to irradiate the laser beam onto at least one mirror included in the projection optics.
