  • Solid state imager with inorganic lens array
    Patent number: 6211916
    Abstract: An imager, including: a semiconductor substrate; a plurality of spaced image pixels formed in the substrate; and a dielectric layer formed over the image pixels, the dielectric layer having a top surface. The imager further includes a plurality of depressions formed in the top surface; and a plurality of lenses having top surfaces, each lens formed in the depression corresponding to an underlying image pixel, the top surface of each lens being optically planar with the top surface of the dielectric.
    Type: Grant
    Filed: March 11, 1996
    Date of Patent: April 3, 2001
    Assignee: Eastman Kodak Company
    Inventors: Gilbert Alan Hawkins, David Newell Nichols, David Lawrence Losee, Robert Leroy Nielsen
  • Planar color filter array for CCDs with embedded color filter elements
    Patent number: 5889277
    Abstract: An image sensor and method of making such sensor is described. The sensor includes an integral color filter array, comprising: a semiconductor substrate having an optically planar top surface; a plurality of spaced image pixels formed in the substrate; and an array of physically contiguous color filter elements embedded in the substrate whose top and bottom surfaces are coplanar and which have no overlap of color filter layers between adjacent color filter elements.

    Filed: December 9, 1996
    Date of Patent: March 30, 1999
    Assignee: Eastman Kodak Company
    Inventors: Gilbert Allan Hawkins, David Lawrence Losee, Robert Leroy Nielsen, Ronald W. Wake
  • Method for forming inorganic lens array for solid state imager
    Patent number: 5824236
    Abstract: A method of making an imager including the steps of providing a semiconductor substrate; forming a plurality of spaced image pixels in the substrate; depositing a dielectric layer over the image pixels and making this layer optically planar by chemical mechanical polishing, thereby forming an optically flat surface. The method further includes forming a plurality of depressions in the optically flat surface; uniformly depositing a lens material on the optically flat surface, entirely filling the depressions; and forming the lens material.
