  • TEXTURING OF MONOCRYSTALLINE SEMICONDUCTOR SUBSTRATES TO REDUCE INCIDENT LIGHT REFLECTANCE
    Publication number: 20140004701
    Abstract: Monocrystalline semiconductor substrates are textured with alkaline solutions to form pyramid structures on their surfaces to reduce incident light reflectance and improve light absorption of the wafers. The alkaline baths include compounds which inhibit the formation of flat areas between pyramid structures to improve the light adsorption.

  • Composition for circuit board manufacture
    Patent number: 6261466
    Abstract: A process and composition for treating a metal surface to increase its surface roughness for subsequent adhesion to a polymer layer. The composition comprises hydrogen peroxide, inorganic acid, an amine free of a surfactant group and optionally, a corrosion inhibitor. The composition is characterized by elimination of a surfactant from solution.
    Type: Grant
