Embodiments of the present disclosure provide a cover assembly that includes a cover disposed between a device side surface of a substrate and a reflector plate, which are disposed within a thermal processing chamber. The presence of the cover between the device side surface of a substrate and a reflector plate has many advantages over conventional thermal processing chamber designs, which include an improved temperature uniformity during processing, a reduced chamber down time and an improved cost-of-ownership of the processes performed in the thermal processing chamber.

Multilayer structure as reflector


The present invention relates to a multilayer structure comprising a) a functional film comprising a vis/ir-reflecting metal layer on a carrier film, wherein the carrier film can be in single-layer form or in the form of a uv- and/or uv/vis-reflecting multi-ply layer, and at least one adhesive layer, and optionally at least one scratch-resistant layer, b) a functional layer comprising a layer of metal nitrides, metal oxides or semimetal oxides, mixed oxides or metals, wherein the layer can additionally have a coating, c) optionally a carrier film, d) optionally an adhesive layer, e) a substrate layer. By means of such a multilayer structure it is possible, in the adhesive bonding of thin functional films by means of a psa (“pressure sensitive adhesive”) to thermoplastics such as, for example, polycarbonate, largely to avoid blistering of the adhesively bonded film in the case of outside use (in a changing climate)..
