Jiangxi Jiayin Optoelectronic Materials Co., Ltd.

Jiangxi Jiayin Optoelectronic Materials Co., Ltd. was established in June 2011, located in Nanchang Economic and Technological Development Zone. The company specializes in producing high-purity metal organic compounds (MO sources) with independent intellectual property rights. The product purity reaches 6N (i.e., 99.9999%) or above. The products have passed appraisal or acceptance organized by national authoritative departments, and the overall product quality has reached the advanced level of similar products in the world. The company is the fifth in the world and the second in China to master the production technology of high-purity metal organic sources (MO sources), a technology-intensive enterprise. It has developed and possesses high-tech integrating synthesis and preparation under extreme conditions, ultra-pure purification, ultra-pure analysis, and ultra-pure filling. The quality of products such as high-purity trimethylgallium has reached a * level. The company has a strong R&D and management team, focusing on the development of high-purity MO sources and other semiconductor-specific chemicals. It positions its main business in high-purity metal organic compounds (MO sources), based on international advanced levels and substituting imported products. The main products include high-purity trimethylgallium (TMGa), high-purity trimethylindium (TMI), and triethylgallium (TEGa), etc. As a leading supplier of MO sources in the industry, Jiangxi Jiayin Optoelectronic is committed to providing high-quality solutions for the R&D and mass production of epitaxial wafers. To meet the demand for long-term stable supply of MO sources, the company has established a dedicated doctoral R&D team that has made hundreds of improvements to production processes, cylinder structures, packaging processes, etc., greatly reducing external contamination of MO sources during production and greatly improving the stability of MO sources during cylinder use. Each packaged MO source is individually tested to ensure that every MO source used by customers is qualified. Analysis: We use inductively coupled plasma mass spectrometry (ICP-MS) and nuclear magnetic resonance (NMR) technology to ensure our product purity reaches 6N. Phase I plan: annual production of 20 tons of trimethylgallium, 2 tons of trimethylindium, and 6 tons of triethylgallium, with a total investment of 280 million yuan and an estimated total output value of 1.35 billion yuan. Phase II plan: annual production of 5 tons of di-tert-butyltellurium, 1000 tons of diethylzinc, and 1000 tons of silicon tetrahydride, with an estimated total output value of 4.2 billion yuan. We invest heavily in chemicals for the semiconductor industry because we are confident that Jiayin Optoelectronic will become a globally renowned semiconductor-specific chemicals company.
