  • Patent number: 9281463
    Abstract: Metal oxide tunnel barrier layers for superconducting tunnel junctions are formed by atomic layer deposition. Both precursors include a metal (which may be the same metal or may be different). The first precursor is a metal alkoxide with oxygen bonded to the metal, and the second precursor is an oxygen-free metal precursor with an alkyl-reactive ligand such as a halogen or methyl group. The alkyl-reactive ligand reacts with the alkyl group of the alkoxide, forming a detached by-product and leaving a metal oxide monolayer. The temperature is selected to promote the reaction without causing the metal alkoxide to self-decompose. The oxygen in the alkoxide precursor is bonded to a metal before entering the chamber and remains bonded throughout the reaction that forms the monolayer. Therefore, the oxygen used in this process has no opportunity to oxidize the underlying superconducting electrode.

    Abstract: It is an object of the present invention to provide a technology for manufacturing a highly reliable display device at a low cost with high yield. In the present invention, a spacer is formed over a pixel electrode, thereby protecting the pixel electrode layer from a mask in formation of an electroluminescent layer. In addition, since a layer that includes an organic material that has water permeability is sealed in a display device with a sealing material and the sealing material and the layer that includes the organic material are not in contact, deterioration of a light-emitting element due to a contaminant such as water can be prevented. The sealing material is formed in a portion of a driver circuit region in the display device, and thus, the narrower frame margin of the display device can also be accomplished.
