Abstract
A method for fabricating an LED that radiates white spectrum light. A phosphor that radiates a white spectrum after excitation in the blue or UV spectrum is uniformly deposited onto a GaN epitaxial wafer prior to die separation and packaging. This allows wafer-level processing and probing of white LEDs and produces true white LED chips.
