Claim 21:
22. A method of forming a device, comprising:
depositing an anode and a pixel isolation structures (PIS) layer over a substrate;
removing portions of the PIS layer to form a first PIS disposed along a line plane and a second PIS disposed along a pixel plane;
depositing a first structure layer, an adhesion material or a seed material and a second structure layer over the substrate, wherein the second structure layer is deposited by sputter deposition;
depositing and patterning a first resist over the second structure layer;
removing a portion of the second structure layer and the adhesion material or the seed material to form a second structure and an adhesion layer or a seed layer layer using ion beam milling;
removing the first resist from the second structure;
depositing and patterning a second resist over the first structure layer;
dry etching and removing a portion of the first structure layer to form a first structure;
depositing an organic light emitting diode (OLED) material, a cathode, and an encapsulation layer;
depositing and patterning a third resist in a first sub-pixel;
ashing and removing a portion of the OLED material, the cathode, and the encapsulation layer; and
removing the third resist.
