  • Transparent article having protective silicon nitride film
    Patent number: 7101810
    Abstract: Transparent articles comprising transparent, nonmetallic substrate and a transparent film stack is sputter deposited on the substrate. The film stack is characterized by including at least one infrared reflective metal film, a dielectric film over the metal film, and a protective silicon nitride film of 10 ? to 150 ? in thickness over the said dielectric film. The dielectric film desirably has substantially the same index of refraction as does silicon nitride and is contiguous with the silicon nitride film.
    Type: Grant
    Filed: April 7, 2005
    Date of Patent: September 5, 2006
    Assignee: Cardinal CG Company

  • Transparent article having protective silicon nitride film
    Patent number: 5834103
    Abstract: Transparent articles comprising transparent, nonmetallic substrate and a transparent film stack is sputter deposited on the substrate. The film stack is characterized by including at least one infrared reflective metal film, a dielectric film over the metal film, and a protective silicon nitride film of 10 .ANG. to 150 .ANG. in thickness over the said dielectric film. The dielectric film desirably has substantially the same index of refraction as does silicon nitride and is contiguous with the silicon nitride film.
