Latest Patents

One of his latest patents is for low-emissivity and anti-solar glazing. This invention relates to glazing systems that maintain their properties even when subjected to heat treatment. The system comprises a stack of thin layers with an alternating arrangement of infrared radiation reflecting functional layers and dielectric coatings. The first dielectric coating is made from an oxide in contact with the substrate. The coating stack includes a barrier layer, a zinc oxide-based layer, a layer of zinc-tin mixed oxide, and a nucleation layer. The last dielectric coating features an oxide layer with a thickness greater than 3 nm, overlaid with a silicon nitride or silicon oxide layer thicker than 10 nm.

Another significant patent involves a method for producing a coated item through texture etching. This method includes the deposition of at least one transparent, conductive metal-oxide layer on a substrate. The process involves a deposition step followed by a temperature treatment. After this treatment, the surface texture of the coating is adjusted through an etching process.
