VERTICALLY STRUCTURED LED BY INTEGRATING NITRIDE SEMICONDUCTORS WITH Zn(Mg,Cd,Be)O(S,Se) AND METHOD FOR MAKING SAME

摘要

A light emitting diode (LED) with a vertical structure, including electrical contacts on opposing sides, provides increased brightness. In some embodiments an LED includes a nitride semiconductor light emitting component grown on a sapphire substrate, a Zn(Mg,Cd,Be)O(S,Se) assembly formed on the nitride semiconductor component, and a further Zn(Mg,Cd,Be)O(S,Se) assembly bonded on an opposing side of the light emitting component, which is exposed by removing the sapphire substrate. Electrical contacts may be connected to the Zn(Mg,Cd,Be)O(S,Se) assembly and the further Zn(Mg,Cd,Be)O(S,Se) assembly. Herein Zn(Mg,Cd,Be)O(S,Se) is a II-VI semiconductor satisfying a formula Zn1-a-b-cMgaCdbBecO1-p-qSpSeq, wherein a=0~1, b=0~1, c=0~1, p=0~1, and q=0~1.
