<p>A method for depositing a layer of phosphor-containing material on a plurality of LED (light-emitting diode) dies on a wafer includes disposing a layer of dry photoresist film over a plurality of LED dies on a wafer, disposing a mask layer over the dry photoresist film, and patterning the dry photoresist film to form a plurality of openings in the dry photoresist film to expose a top surface of each of the LED dies. The method also includes depositing a phosphor-containing material on the exposed top surface of each the LED dies using a screen printing process, and removing the patterned dry photoresist film.</p> |
