Abstract
A method for selectively heating a film on a substrate. The film is provided with a different absorption characteristic for light than the absorption characteristic of the substrate. The specimen (combined film and substrate) is illuminated by light having a maximum intensity at a wavelength which will be substantially absorbed by the film and substantially not absorbed by the substrate.
