Patent ID: 7291529

Claim:
A method of processing a semiconductor wafer to form a light emitting device, comprising: forming a plurality of Light Emitting Devices (LED) on a semiconductor wafer having a first thickness; contacting the plurality of LEDs on the wafer to a surface of a carrier to couple the wafer to the carrier; reducing the first thickness of the wafer to a second thickness that is less than the first thickness by processing a backside surface of the wafer; separating the carrier from the plurality of LEDs on the wafer; and cutting the wafer to separate the plurality of LEDs, wherein reducing the first thickness of the wafer to a second thickness is followed by: processing the backside surface of the wafer opposite the plurality of LEDs to improve light extraction wherein processing comprises laser patterning the backside surface; and forming a plurality of respective contacts on the backside surface opposite where respective bonding pads are to be formed on the plurality of LEDs.
