Appl. No.:

15/518506

Inventors:

- Tortola, VG
Brian Arthur Bucci - Pittsburgh PA, US

International Classification:

C23C 14/04

Abstract:

In a multi-mask alignment system and method, a carrier frame is provided having a number of apertures therethrough. A number of shadow mask-frame combinations are also provided. Each shadow mask-frame combination includes a first set of alignment features and each shadow mask-frame combination is positioned on a first side of the carrier with the frame supporting the shadow mask in alignment with one of the apertures. An alignment system is provided and a control system including a programmed controller is also provided. Under the control of the controller, the alignment system is caused to adjust the position of each shadow mask-frame combination with respect to the carrier based on positions of the first set of alignment features determined by the controller.

Abstract:

In a shadow mask tensioning method and apparatus, a shadow mask supported by a support frame is positioned between a shadow mask frame and a set of actuators with a portion of the shadow mask extending across a gap between the support frame and the shadow mask frame. Under the control of a programmed controller, the set of actuators is caused to simultaneously displace numerous, spaced locations of the portion of the shadow mask into the gap to align alignment apertures of the shadow mask to predetermined positons in fields of view of cameras positioned to observe the alignment apertures. The shadow mask is then affixed to the shadow mask frame.

- Tortola, VG
Brian Arthur Bucci - Pittsburgh PA, US

International Classification:

G03F 7/20

Abstract:

In a system and method of shadow mask tensioning, an object having second set of alignment features is positioned on a side of shadow mask having a first set of alignment features such that the object and the shadow mask can move independently of each other and the first and second sets of alignment features are not in final alignment. Tension is then applied to the shadow mask to bring the first set of alignment features into final alignment with the second set of alignment features. The alignment features of the shadow mask can include at least one deposition aperture of the shadow mask.

US Classification:

29448, 292811

Abstract:

In a method and apparatus for shadow mask tensioning, a shadow mask frame and an anchor frame are positioned in spaced relation defining a gap therebetween and a shadow mask is positioned on the shadow mask frame and the anchor frame with an interior portion of the shadow mask extending across the gap. An edge of the shadow mask is affixed to the anchor frame and the shadow mask is tensioned by urging the interior portion of the shadow mask into the gap. Once the shadow mask has been tensioned to a desired extent, the shadow mask is affixed to the shadow mask frame. Thereafter, the combination of the shadow mask affixed to the shadow mask frame is separated from the anchor frame.
