Patent ID: 8871545

Claim:
A method of forming a multi-color OLED device, including: a. first providing a substrate having a first patterned electrode; b. coating a photoresist solution over the substrate to form a first photo-patternable layer, wherein the solution includes a fluorinated photoresist material and a first fluorinated solvent; c. selectively exposing portions of the first photo-patternable layer to radiation to form a first pattern of exposed fluorinated photoresist material and a second pattern of unexposed fluorinated photoresist material; d. exposing the substrate to a second fluorinated solvent to develop the first photo-patternable layer, removing the second pattern of unexposed fluorinated photoresist material without removing the first pattern of exposed fluorinated photoresist material; e. depositing at least a first organic light-emitting material over the substrate to form a first organic light-emitting layer; f. applying the first pattern of exposed fluorinated photoresist to control the removal of a portion of the first organic light-emitting layer; g. coating the photoresist solution over the substrate and the remaining first organic light-emitting layer to form a second photo-patternable layer; h. selectively exposing portions of the second photo-patternable layer to radiation to form a third pattern of exposed fluorinated photoresist material and a fourth pattern of unexposed fluorinated photoresist material wherein the third pattern of exposed fluorinated photoresist material is arranged differently on the substrate than the first pattern of exposed fluorinated photoresist; i. exposing the substrate to the second fluorinated solvent to develop the second photo-patternable layer, removing the fourth pattern of unexposed fluorinated photoresist material without removing the third pattern of exposed fluorinated photoresist material; j. depositing at least a second light-emitting material over the substrate to form a second light-emitting layer; and k. applying the third pattern of exposed fluorinated photoresist material to control the removal of a portion of the second organic light-emitting layer.
