A process for forming layers on a substrate including irradiating at least part of an aluminum nitride surface with a high power ultraviolet emitter resulting in the elimination of the nitride component to form an aluminum layer. The aluminum layer is then reinforced by a metal.

Method for forming layers by UV radiation of aluminum nitride

The process removes or partially structures the surface of a substrate of a polymer, i.e. polyamide, polyimide and polycarbonate. The surface of the substrate is irradiated in a vacuum with an incoherent UV radiation which has a wavelength of 60 nm to 400 nm, preferably a wavelength of 172 nm. In order to form the structures, a mask is placed on the surface of the substrate.

Process for removing and/or structuring surfaces by irradiating with a

An apparatus for coating substrates by photolytic dissociation or decomposition of a coating material includes a reactor vessel. A UV radiation source and the substrate to be coated are both disposed in the reactor vessel.

Coating apparatus

A method for producing full-surface or partial metal films on a substrate includes placing a coating on a substrate. The coating is irradiated sheetwise with a laser to form the metal films.
