Latest Patents

Li Ma's latest patents include a method for preventing contamination of LED dies. This innovative method allows a reflective layer to abut against an edge of a metal contact while preventing contamination of the metal contact for an LED die. The process involves encapsulating an electrical contact via with a barrier layer prior to the deposition of a reflective film layer. The barrier layer encapsulates the metal contact by defining a mask pattern larger than the metal contact via, which effectively prevents contamination by the reflective film. This encapsulation not only reduces contamination of the metal contact but also minimizes the voltage drop during the operation of the LED die.
