Abstract
Methods are provided for cleaning a substrate. An exemplary method includes irradiating a pathogenic formation on a surface of the substrate with radiation in a wavelength range of 350 nm to 800 nm, wherein the substrate includes metal particles on the surface of the substrate, and wherein a highest temperature of the metal particles during the irradiation is less than or equal to 45° C.; and delaminating the pathogenic formation from the substrate.
