Claim Text:
1. A method for depositing a layer on a substrate, comprising: flowing a fluid precursor radially across a surface of the substrate disposed within a processing chamber in a laminar manner so that the surface of the substrate is immersed in the fluid precursor; directing an electromagnetic radiation generated from a radiation source to a rotary scanning unit such that the electromagnetic radiation is deflected and scanned, in a predetermined shape of illumination, across the substrate at or near the surface upon which a material layer is to be deposited; and initiating an epitaxial process with the electromagnetic radiation having a wavelength selected for photolytic dissociation of the fluid precursor by irradiating the fluid precursor at or near the surface of the substrate to epitaxially form the material layer onto the surface of the substrate at a temperature less than about 400° C.
