摘要：
The present disclosure provides a method of patterning a phosphor layer on a light emitting diode (LED) emitter. The method includes providing at least one LED emitter disposed on a substrate; forming a polymer layer over the at least one LED emitter; providing a mask over the polymer layer and the at least one LED emitter; etching the polymer layer through the mask to expose the at least one LED emitter within a cavity having polymer layer walls; and coating the at least one LED emitter with phosphor.
