Guangming research LED Technology

Guangming Chemical Research and Design Institute held the day before the production process of GaN based LED and special gas application symposium. The report will play a technical advantage for the Guangming, targeted research and development to provide guidance for the production of LED gas. Long engaged in LED R & D and production of well-known experts at the meeting made a wonderful technical seminars.

Experts demonstrated the GaN based LED chip manufacturing process, and a detailed explanation of high purity ammonia, Gao Chunqing, high-purity nitrogen, silane / hydrogen gas mixture and MO source in the LED epitaxial wafer and chip manufacturing process. Guangming researchers on the LED industry status and development trends, the impact of gas purity on the quality of LED costs and other related issues and experts to communicate and discuss.
