Phosphor-coated light emitting diodes including tapered sidewalls, and fabrication methods therefor

A light emitting diode includes a substrate having first and second opposing faces and a sidewall 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 is provided on the oblique sidewall. The oblique sidewall can allow more uniform phosphor coatings than conventional orthogonal sidewalls.
