Abstract
A laser beam machining method includes emitting light from a light source to illuminate a mask which has both openings through which light can pass to the object to be machined and blocking parts through which substantially no light can pass. By utilizing the energy of the light, those portions of the object which are exposed through the openings are machined by ablation. The shape and width of both the openings and the blocking parts can be adjusted so as to provide the energy distribution required to form an object of the desired shape and size.
