Patent ID: 7938936

Claim:
A method of fabricating an organic electro-luminescence device comprising the following steps: providing a substrate, an organic chamber, and a sputtering chamber; forming a hole injection layer on the substrate; forming a hole transport layer on the hole injection layer in the organic chamber; forming a light-emitting layer on the hole transport layer in the organic chamber; disposing aluminum chelate (Alq3) on the light-emitting layer and partially doping a CsF compound into the aluminum chelate (Alq3) to form an electron transporting layer in the organic chamber, wherein only a top portion of the electron transporting layer is doped with the CsF compound, and the other portion of the electron transporting layer is un-doped; forming a buffer layer on the electron transporting layer in the organic chamber; transferring the substrate, the hole injection layer, the hole transport layer, light-emitting layer, the electron transporting layer, and the buffer layer from the organic chamber to the sputtering chamber; and forming an electron injection layer on the buffer layer in the sputtering chamber.
