Abstract
Described are light emitting diode (LED) devices comprising a mesa with semiconductor layers, the semiconductor layers including an N-type layer, an active layer, and a P-type layer. A patterned transparent conductive oxide layer is on the top surface of the mesa. The patterned transparent conductive oxide layer has a first portion with a first thickness and a second portion with a second thickness, the second thickness less than the first thickness. Optical loss of the LED is reduced in the thinned region of the transparent conductive oxide layer.
