A high efficient luminous crystal chip developed by Shanghai Institute of Optics and mechanics

Shanghai science and Technology Institute of Chinese Academy of Sciences undertaken by the Shanghai science and technology research project "efficient luminous non-polar GaN based LED substrate lithium aluminate crystal and wafer development" through the acceptance of the Shanghai Municipal Science and technology commission.

The project team developed a 2 inch diameter greater than 100 mm in length of the lithium aluminate crystal 11, more than and 300 pieces of wafer preparation, technical indicators have reached or exceeded the assessment requirements, the wafer quality specifications to achieve practical, and to provide Shanghai blue Nanjing University found the user; (302) LiAlO2 substrate than in polishing, extension, stability etc. (100) LiAlO2 (302) substrate, pointed out that the LiAlO2 substrate can be prepared as a non-polar substrate surface model a GaN-LED light emitting device. The panel believes that the project provides technical and intellectual property reserves for the application of lithium aluminate crystals and wafers in semiconductor white light lighting.
