Patent ID: 8114698

Claim:
A method for fabricating a III-nitride light emitting diode (LED), comprising: texturing at least one surface of a semipolar or nonpolar plane of a III-nitride layer of the LED to form a textured surface, wherein the texturing step is performed by plasma assisted chemical etching and comprises the steps of: (1) creating at least one feature with at least one sidewall that reflects and transmits at least one light ray incident from inside the feature; and (2) inclining the sidewall such that each time the ray is reflected, an angle of incidence of the ray relative to a surface normal of the sidewall decreases, such that: (a) when the angle of incidence of the ray is smaller than a critical angle, the ray's transmission through the sidewall is increased, and (b) when the angle of incidence of the ray is at least equal to the critical angle, the ray is reflected by the sidewall.
