  • Transparent substrate with laminated film
    Patent number: 11697269
    Abstract: A transparent substrate with a laminated film, which comprises a transparent substrate and a laminated film formed on at least one surface of the transparent substrate, wherein the laminated film has a first dielectric layer, a crystallinity-improving layer, a functional layer and a second dielectric layer in this order from the transparent substrate side, the crystallinity-improving layer contains ZrNx (wherein x is higher than 1.2 and at most 2.0), the functional layer contains at least one metal nitride selected from the group consisting of titanium nitride, chromium nitride, niobium nitride, molybdenum nitride and hafnium nitride, and the concentration of oxygen atoms at a boundary between the crystallinity-improving layer and the functional layer, is at most 20 atom %.
    Type: Grant
