  • Method for improving alignment precision in forming color filter array
    Publication number: 20020102812
    Abstract: A method for improving alignment precision in forming a color filter array is disclosed. This method comprises providing a substrate having a node region in the substrate and a dielectric layer on the substrate, and etching a portion of the dielectric layer to expose the node region. As a result, the alignment precision is improved by use of the node region with enhanced step height to increase the intensity of signal in a semiconductor process.
