主权项

1. A method for coating violet-emitting LED die with densely-packed-luminescent-materials, comprising:
attaching an arrangement of a one or more violet-emitting LED die to a submount structure; applying a photoresist characterized by a thickness greater than a height of at least some of the one or more violet-emitting LED die; opening a first cavity hole in the photoresist around at least some of the one or more violet-emitting LED die; dispensing a luminescent material into the first cavity hole; and stripping the photoresist to provide one or more densely-packed-luminescent-materials coated violet-emitting LED die.
