  • Method for vacuum deposit on a curved substrate
    Patent number: 7122223
    Abstract: The invention concerns a method which consists in a process known per se in producing, on the curved substrate (10) to be treated, a film of material derived from a specific material source (13). The invention is characterized in that it consists in inserting, between the curved substrate (10) and the material source (13), a mask (19) relative to the curved substrate (10), preferably selecting as mask (19), a mask comprising a ring-shaped part (20).

  • Organic substrate having optical layers deposited by magnetron sputtering and method for preparing it
    Patent number: 6596368
    Abstract: An organic substrate having optically-active layers deposited by magnetron sputtering and a preparation process for it are provided. Gas pressure used for carrying out better adhesion by sputtering is high, comprised between 0.8 and 5.0 Pa. Sputtering is particularly suitable for targets of Si, Ti, Zr and organic substrates with or without anti-abrasive coating. Improved adhesion of thin films is obtained.
