Abstract
A sputtering system for the depositing or etching of insulating, conducting, or semiconducting thin films is disclosed, in which the sputtering plasma is irradiated with a transverse, adjustable ultraviolet emission produced by an ultraviolet optical cavity containing a lamp discharge. The cavity irradiates the sputtering plasma volume with a sufficiently high optical flux to enact significant changes in the film produced. This effect is enabled by the device geometry, which, in the preferred embodiment, provides uniquely high efficiency and stability in the optical coupling between the lamp discharge and the sputtering plasma, resulting in the ability to significantly alter ionized and excited state populations within or above the sputtering plasma. The design also allows the operator to significantly control the volume and species involved in the optical interaction. A novel ultraviolet source for materials processing is also disclosed.
