Abstract:
System for wafer-level phosphor deposition. In an aspect, a semiconductor wafer is provided that includes a plurality of LED dies wherein at least one die includes an electrical contact, a photo-resist post covering the electrical contact, and a phosphor deposition layer covering the semiconductor wafer and surrounding the photo-resist post. In another aspect, a semiconductor wafer is provided that comprises a plurality of LED dies wherein at least one die comprises an electrical contact, a phosphor deposition layer covering the semiconductor wafer, and a cavity in the phosphor deposition layer exposing the at least one electrical contact.
