    摘要: A method and system for treating a substrate and, in particular, a method and system for cleaning a low dielectric constant (low-k) dielectric film to remove, among other things, undesired residue is described. The method includes irradiating a region on a substrate containing one or more layers or structures with infrared (IR) radiation and optionally ultraviolet (UV) radiation to remove material or undesired residues from the one or more layers or structures. Furthermore, the method may optionally include exposing at least a portion of the region to a gas or vapor jet emanating from a gas nozzle along a jet axis in a direction towards the substrate.
