PHOSPHOR-COATED LIGHT EMITTING DIODES INCLUDING TAPERED SIDEWALLS, AND FABRICATION METHODS THEREFOR

摘要

A LIGHT EMITTING DIODE INCLUDES A SUBSTRATE (200) HAVING FIRST (200A) AND SECOND (200B) OPPOSING FACES AND A SIDEWALL (200D) BETWEEN THE FIRST AND SECOND OPPOSING FACES THAT EXTENDS AT AN OBLIQUE ANGLE FROM THE SECOND FACE TOWARDS THE FIRST FACE. A CONFORMAL PHOSPHOR LAYER (220) IS PROVIDED ON THE OBLIQUE SIDEWALL. THE OBLIQUE SIDEWALL CAN ALLOW MORE UNIFORM PHOSPHOR COATINGS THAN CONVENTIONAL ORTHOGONAL SIDEWALLS.(FIG.1A)
