Classification: CPC H  C | IPC C  H

Claim 9:
10. A coating device for a curved substrate, comprising:
a chamber;
a carrying platform disposed in the chamber and having a first surface, wherein the carrying platform is configured to carry a curved substrate and the curved substrate has a second surface;
a sputtering device disposed in the chamber and corresponding to the carrying platform, wherein the sputtering device comprises a sputtering target and is configured to sputter a coating material to a first part and a second part of the second surface of the curved substrate;
a processor for storing data, wherein the data comprises a distance between the first part of the second surface of the curved substrate and the first surface of the carrying platform, and a distance between the second part of the second surface of the curved substrate and the first surface of the carrying platform; and
a position-adjusting device disposed in the chamber, and the position-adjusting device connected to at least one of the sputtering device and the carrying platform, wherein the position-adjusting device is configured to adjust the sputtering device to a first position and a second position in a first direction according to the data stored in the processor, wherein the first direction is parallel to a normal direction of the first surface of the carrying platform,
wherein when the sputtering device is at the first position in the first direction, the coating material is sputtered on the first part of the second surface of the curved substrate, and when the sputtering device is at the second position in the first direction, the coating material is sputtered on the second part of the second surface of the curved substrate.
