Latest Patents
Ratautas's latest patents include a "Method for selective metallisation of inorganic dielectrics or semiconductors." This invention describes a process for selectively depositing metal on the surfaces of inorganic dielectric materials such as glass, ceramics, or semiconductor materials. The method enables the rapid and precise formation of electric circuits on both flat and three-dimensional surfaces. The production method includes several steps: firstly, treatment of an item surface with an ultrashort pulse laser of the areas for metallisation, followed by pre-treatment with the R—OH solution and metal salt catalyst activation in a bath. Finally, electroless metal plating is performed. During immersion in the metal salt catalyst activation bath, localized R—OH molecules on the item's surface act as reducing agents, facilitating the reduction of metal ions from the activation bath. This results in the formation of catalytic seeds exclusively at the laser-modified areas, ensuring high adhesion of the metal layers to the dielectric surface due to the formation of chemical bonds.
Another significant patent is the "Method for formation of electro-conductive traces on polymeric article surface." This invention relates to the production of electro-conductive traces on the surface of polymeric articles using laser excitation for the areas to be metallised. The process involves activating the laser-treated areas with a metal salt solution, rinsing the article in distilled water, and subsequently metallising the activated areas in a chemical plating bath. The aims of this invention are to produce cost-effective conductive traces for application in 3D moulded interconnect devices and to enhance the quality of the circuit traces by improving the selective metallization process. The irradiation dose and scanning parameters for surface excitation are chosen experimentally, ensuring that any surface degradation of the polymer is avoided.
