8642369, Feb 4, 2014

Filed:

Mar 3, 2009

Appl. No.:

12/397224

Inventors:

Jizhi Zhang - Arcadia CA, US
Jin Joo Song - Brea CA, US

Assignee:

ZN Technology, Inc. - Brea CA

International Classification:

H01L 21/00

US Classification:

438 47, 438104, 257E33064

Abstract:

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 ZnMgCdBeOSSe, wherein a=01, b=01, c=01, p=01, and q=01.

International Classification:

H01L 31/109

US Classification:

257014000

Abstract:

A highly efficient III-nitride/II-Oxide light emitting device that has a n-tunneling layer, which comprises at least one material selected from a group consisting of n-GaN, n-InGaN, n-AlGaN, n-AlGaInN, n-ZnO, n-ZnCdO, n-ZnMgO, n-ZnMgCdO, that is deposited on top of the p-layer in a LED structure. After that, a top n-layer is deposited above that n-tunneling layer that may be a n-layer and comprises at least one material selected from a group consisting of n-GaN, n-InGaN, n-AlGaN, n-AlGaInN, n-ZnO, n-ZnCdO, n-ZnMgO, n-ZnMgCdO or a top n-layer may also be a n-layer and comprises at least one material selected from a group consisting of n-GaN, n-InGaN, n-AlGaN, n-AlGaInN, n-ZnO, n-ZnCdO, n-ZnMgO, n-ZnMgCdO so that the top n-layer is made highly conductive and show very rough surface.
