Publication number: 20110003420Abstract: The present invention discloses a method for fabricating gallium nitride(GaN)-based compound semiconductors. Particularly, this invention relates to a method of forming a transition layer on a zinc oxide (ZnO)-based semiconductor layer by the steps of forming a wetting layer and making the wetting layer nitridation. The method not only provides a function of protecting the ZnO-based semiconductor layer, but also uses the transition layer as a buffer layer for a following epitaxial growth of a GaN-based semiconductor layer, and thus, the invention may improve the crystal quality of the GaN-based semiconductor layer effectively.Type: ApplicationFiled: December 4, 2009Publication date: January 6, 2011Applicant: SINO-AMERICAN SILICON PRODUCTS INC.Inventors: Miin-Jang Chen, Sheng-Fu Yu, Ray-Ming Lin, Wen-Ching Hsu, Szu-Hua Ho

Patent number: 7659549Abstract: The present invention is a method for obtaining a better color rendering with a photoluminescence plate, and the better color rendering is obtained by using UV radiating on the photoluminescence plate stacked with a red photoluminescence plate, a green photoluminescence plate and a blue photoluminescence plate. Therefore, the color rendering is above 90% and close to the solar light. The photoluminescence plate can be made from directly coated with photoluminescence layers of three colors or with fully mixed fluorescent materials of three colors. Consequently, a white light relied on the present invention is more uniform than the conventional techniques with a color mixing performance based on tricolor LEDs.Type: GrantFiled: October 23, 2006Date of Patent: February 9, 2010Assignee: Chang Gung UniversityInventors: Ray-Ming Lin, Jen-Chih Li, Yung-Hsiang Lin, Yuan-Chieh Lu, Yi-Lun Chou
