Beijing Tongmei Crystal Technology Co., Ltd.

Beijing Tongmei Crystal Technology Co., Ltd. was founded in September 1998, and is a wholly-owned enterprise of the American AXT Group (listed on NASDAQ). The company is located in Tongzhou Industrial Development Zone, Beijing, with a registered capital of USD 30.13 million and a total investment of USD 50.76 million. It covers an area of nearly 50,000 square meters and currently has over 1,000 employees. The company is mainly engaged in the production and processing of gallium arsenide, indium phosphide, and germanium single crystal wafers. The products are mainly used in mobile phones, satellite broadcasting, radar systems, lasers, light-emitting diodes, aviation-grade solar energy and other fields; 90% of products are sold outside mainland China. The company's technical and management levels are at the leading position in the industry, and the entire production process represents the international advanced level of contemporary compound semiconductor materials. This technology is still blank domestically, and internationally only a few countries such as the United States, Germany, and Japan possess it. These process technologies mainly include vertical gradient freeze compound semiconductor crystal growth technology, scratch-free wire sawing process, ultra-flat mechanochemical polishing process, ultra-clean surface cleaning technology, and contamination-free technology for long-term wafer storage, and ultra-thin high-strength germanium wafer processing technology. These are major technical difficulties in the current compound semiconductor field. Since its establishment, the company has fully operated in accordance with AXT and international first-class models in technology, management, and capital operation. Product quality has steadily improved, production output value has maintained a stable and rapid growth trend, receiving high praise from customers worldwide, and achieving good social and economic benefits. The company has passed ISO9001 international quality system and ISO14001 international environmental protection system certifications, and has been awarded the honorary title of "High-tech Foreign-invested Enterprise" by the Beijing Municipal Science and Technology Commission, and has been formally approved as an AA-level management enterprise by customs. For many consecutive years, the company has been awarded multiple honors by district and municipal governments at all levels, such as "Top 50 Industrial Import and Export Enterprises of the Year", "Top 10 Export Earners in the Industrial System", "Top 20 Enterprises by Sales Revenue", "Outstanding Enterprise for Technological Progress and Scientific Management", and "Advanced Enterprise for Quality Management". The rapid development of the world semiconductor materials and optoelectronic communication technology, the progress of China's economy, and the favorable investment environment provide good conditions for the company's growth and expansion. We will be committed to promoting China's and international optoelectronic communication undertakings, and to providing high-quality products to more domestic and international customers.
