Patent ID: 7524708

Claim:
A fabrication method of a light emitting diode comprising steps of: preparing a ( 100 ) substrate tilted toward a first direction and a second direction simultaneously; forming a first cladding layer with a semiconductor material of a first conducive type on the ( 100 ) substrate; forming an active layer on the first cladding layer; and forming a second cladding layer with a semiconductor material of a second conducive type on the active layer, wherein the first direction and the second direction are a [0-1-1] direction and a [0-11] direction, respectively; wherein the ( 100 ) substrate is a III-V or a IV-IV group semiconductor substrate; wherein the ( 100 ) substrate is a ( 100 ) III-V group semiconductor substrate; and wherein the ( 100 ) substrate has a crystal orientation such that a ( 100 ) plane is inclined 2 to 20° toward the [0-1-1] direction and 1 to 8 ° toward the [0-11] direction.
