Abstract: A method for allowing a reflective layer to abut against an edge of a metal contact while preventing contamination of a metal contact for an LED die is provided. The method includes encapsulating an electrical contact (i.e. metal contact) via with a barrier layer prior to deposition of a reflective film layer. The barrier layer encapsulates the metal contact by defining a mask pattern with a larger size than the metal contact via, which prevents the metal contact from becoming contaminated by the reflective film. This encapsulation reduces contamination of the metal contact and also reduces the voltage drop during operation of the LED die.
