ABSTRACT:
A method for forming a screen suitable for screen printing a pattern of small closely spaced features onto a substrate is provided. The method includes the steps of providing a fine mesh screen and then forming a patterning layer on the mesh using a photosensitive emulsion. A mask or phototool is used to pattern the patterning layer. During the patterning process, open areas of the mask are aligned with the openings on the mesh using a microscope or other vision device to align the mask with the mesh. During a screen printing process, the open areas of the patterning layer will thus not be obstructed or split into smaller openings by the screen wires. The patterning layer can be patterned using laser energy directed through the mask or using UV exposure followed by development with a suitable developer.
