Abstract

A method of mounting a deposition mask onto a flexible frame for use in vacuum deposition of material through a pealable deposition mask in forming an OLED, including the steps of providing a plate with the pealable deposition mask formed thereon; providing the flexible frame having border portions, such border portions defining a frame opening which corresponds to border portions on the pealable deposition mask; aligning and then securing the border portions of the flexible frame to the border portions of the pealable deposition mask and removing the flexible frame and secured pealable deposition mask from the plate; and mounting the flexible frame with the pealable deposition mask in a carrier which maintains planarity of the pealable deposition mask during subsequent vacuum deposition of material.

Claims (9)

1. A method of mounting a deposition mask onto a flexible frame for use in vacuum deposition of material through a pealable deposition mask in forming an light-emitting diode, comprising the steps of:

(a) providing a plate with the pealable deposition mask formed thereon;

(b) providing the flexible frame having border portions, the border portions defining a frame opening which corresponds to border portions on the pealable deposition mask;

(c) aligning and then securing the border portions of the flexible frame to the border portions of the pealable deposition mask and removing the flexible frame and secured pealable deposition mask from the plate; and

(d) mounting the flexible frame with the pealable deposition mask in a carrier which maintains planarity of the pealable deposition mask during subsequent vacuum deposition of material.

2. The method of claim 1 further including providing a grip tab on the flexible frame which facilitates a user in removal of the flexible frame and secured pealable deposition mask.

3. The method of claim 1 wherein the pealable deposition mask is formed with alignment targets and the flexible frame includes alignment holes corresponding to the targets on the pealable deposition mask to facilitate alignment.

4. The method of claim 1 wherein the material is organic.

5. The method of claim 1 further providing a keeper which sandwiches the flexible frame with the pealable deposition mask in the carrier.
