Abstract: A method for depositing a layer of phosphor-containing material on a plurality of LED dies includes disposing a template with a plurality of openings on an adhesive tape and disposing each of a plurality of LED dies in one of the plurality of openings of the template. The method also includes forming a patterned dry film photoresist layer over the template and the plurality of LED dies. The photoresist layer has a plurality of openings configured to expose a top surface and side surfaces of each of the LED dies. Next, a phosphor-containing material is disposed on the exposed top surface of each the LED dies. The method further includes removing the photoresist layer and the template.
