Patent ID: 7469638

Claim:
A process for forming an electronic device comprising: forming at least one first electrode over a workpiece; depositing a first layer over the at least one first electrode, wherein the first layer comprises a buffer layer, a charge-injecting layer, a charge-transport layer, a charge-blocking layer, or a combination thereof; placing the workplace onto a chuck with a printing apparatus; maintaining the chuck at a temperature in a range of approximately 5 to 80° C.; continuously printing a first liquid composition onto the first layer along a first segment while the chuck is at the temperature in the range of approximately 5 to 80° C.; curing the first liquid composition to form a first organic active layer; continuously printing a second liquid composition onto the first layer along a second segment while the chuck is at the temperature in the range of approximately 5 to 80° C., wherein: the second liquid composition is different from the first liquid composition; and the second segment is substantially parallel to the first segment; curing the second liquid composition to form a second organic active layer; continuously printing a third liquid composition onto the first layer along a third segment while the chuck is at the temperature in the range of approximately 5 to 80° C., wherein: the third liquid composition is different from each of the first and second liquid compositions; and the third segment is substantially parallel to the first segment; curing the third liquid composition to form a third organic active layer; and forming at least one second electrode over the first, second, and third organic active layers and the at least one first electrode.
