Claim 0:
1. A light emitting diode (LED) chip, comprising:
an n-type layer;
a p-type layer;
an active layer arranged between the n-type layer and the p-type layer, wherein the p-type layer, the active layer, and a portion of the n-type layer form an active LED structure mesa with at least one mesa sidewall, wherein the at least one mesa sidewall forms a shape with a repeating pattern along only a first portion of the at least one mesa sidewall such that a second portion of the at least one mesa sidewall is devoid of any repeating pattern; and
a reflective structure on the active LED structure mesa and on the at least one mesa sidewall, wherein the reflective structure is arranged to cover the repeating pattern.
