  • Deposition method for balancing film stress
    Patent number: 6869816
    Abstract: A film deposition method for an optical component is used to balance two side film stresses of a substrate. A predetermined number of layers of films is deposited on an upper side of the substrate, and then layers of films with similar thickness are deposited on a lower side of the substrate to balance side film stresses of the substrate.
    Type: Grant

  • Color filter fabrication method
    Publication number: 20040185174
    Abstract: The present invention describes a color filter fabrication method. According to the present invention, a removable mask and a substrate are placed in a vacuum evaporator. The removable mask is used to cover partially the substrate and expose the region where the first color dielectric layer forms. When finishing this evaporating process, the removable mask is rotated and moved to the next position, exposing another region where the second color dielectric layer is to be formed by the next evaporating process.
