  • Method for dense pixel fabrication and product thereof
    Patent number: 6930319
    Abstract: A method of fabricating a dense pixel array comprising the steps of: (a) printing a photoresist mask and applying said mask to a semiconductor material substrate to form a masked area and an unmasked area on said substrate; (b) applying a photoresist material layer to the unmasked area of the substrate, then applying a metal layer over the photoresist material layer and the substrate, and then applying a solvent to remove the photoresist material layer and said metal layer applied over said photoresist material layer to leave a plurality of metal layers superimposed over the unmasked area of the substrate; (c) removing the substrate to a depressed substrate surface between the metal layers formed in step (b) to form a plurality of pixels each having an upper metal layer; (d) superimposing an insulative layer over each of the metal layers formed in step (c); (e) forming a hole in at least one of the insulative layers formed in step (d) so as to expose the metal layer under the insulative layer; and (f) superim
