Latest Patents

Yans holds a patent for a method titled "Photoreactive Surface Processing." This invention involves cleaning a substrate surface photoreactively without causing damage. The process utilizes a laser beam of UV radiation delivered at an acute angle to the substrate surface. The beam strikes the surface in a long and narrow reaction region, while both the beam and the substrate are moved relative to one another. This movement allows the beam to sweep across the surface. During this sweeping process, a flow of reactant gas is introduced at the reaction region, where it is excited by the UV laser beam. The acute angle of the beam is carefully calibrated to ensure that foreign materials are removed without damaging the substrate or leaving any residues that could hinder further processing.
