Xiamen SAN-U Optronics Co., Ltd. (hereinafter referred to as "SAN-U Optronics") has officially announced the launch of the "Xiamen SAN-U Optronics Industrial Park", marking a new era of development for this leading enterprise deeply engaged in the semiconductor optoelectronic field.     The total investment of the industrial park project is as high as 250 million yuan, covering a vast area with a total construction area of 48000 square meters, including two modern factory buildings and a fully functional office complex. The project was successfully completed in less than two years, from the groundbreaking at the end of 2022 to the successful topping out in July 2023, and then to the completion and acceptance filing in February this year, demonstrating the efficient construction capability and firm development determination of SAN-U Optronics.     What is particularly noteworthy is that the industrial park has planned 18 advanced production lines, which not only cover the company's existing core product line, but also introduce breakthrough production lines in cutting-edge technology fields such as 5G carrier network equipment optoelectronic devices, high-voltage SiC series products (above 1200V), sensing laser sources, and MEMS chip packaging and testing. A design and research center and related infrastructure have been built to comprehensively enhance the company's R&D and production strength.       At present, the company is actively developing 400G high-speed optical modules for application in the AI field, and the successful development of ultra-low dark current miniPD chips also demonstrates its profound expertise in chip technology. In addition, SAN-U Optronics' 1550nm series products have successfully entered NIO's new energy vehicle supply chain, achieving a leapfrog development from research and development to mass production.

SAN-U Optronics Industrial Park project has successfully obtained the completion acceptance filing certificate.     The construction area of SAN-U Optronics Industrial Park is about 47400 square meters, with a total investment of about 250 million yuan. It is expected that in the second quarter, SAN-U Optronics will gradually start the relocation of production lines, actively integrate into Xiamen's high-tech industry layout, and strive to become the main supplier of lasers and sensors in China, as well as the leader in segmented tracks. After use, it will promote upstream chip manufacturers around Xiamen to accelerate chip design, and at the same time provide cost-effective optical devices for domestic downstream enterprises, which is conducive to improving the layout of the entire semiconductor industry chain in Xiamen.     Xiamen SAN-U Optronics Co., Ltd. was established in 2001. It is a high-tech enterprise engaged in the research and mass production of high-speed semiconductor lasers/detectors, optical components, and optical modules. Its products are widely used in fields such as cloud computing, optical communication, fiber to the home, and sensing and detection. On the basis of achieving automated mass production of optical communication devices, intelligent packaging and testing platforms for semiconductor chips such as optoelectronic sensing and IoT system applications have been developed, and multiple production lines have been established for laser radar, MEMS sensor devices, sensing laser sources, SiC devices and modules.

        On July 1, 2023, the SAN-U Optronics Industrial Park project located in Tongxianggao New City was successfully capped. SAN-U Optronic expanded its investment in Xiamen Torch High tech Zone and built a new SAN-U Optronic Industrial Park, marking a milestone in project construction.         The total construction area of the SAN-U Optronics Industrial Park project is approximately 48000 square meters, including two factory buildings and one office complex building. The project will commence at the end of 2022, with a planned construction period of 24 months. The project plans to build 18 production lines. In addition to integrating existing production lines, it will also build a design and development center for 5G carrier network equipment optoelectronic devices, SiC (silicon carbide) series products above 1200V, sensing laser light sources, MEMS (micro electromechanical system) chip sealing and testing, as well as supporting infrastructure. This is of great significance for improving the overall layout of the semiconductor industry chain in our city.         We will implement and transform the early research and development achievements and ongoing projects through key laboratories, pilot production lines, and fully intelligent production lines in the industrial park. According to Li Ling, Chairman of SAN-U Optronics, the new industrial park is beneficial for the company to integrate and upgrade its production layout, expand production capacity, and improve production efficiency. Among them, the intelligent production line of the industrial park will mass produce a series of new products, such as MEMS sensors for methane gas monitoring, semiconductor lasers for unmanned driving, drones, and other fields.         It is worth noting that the SAN-U Optronics Industrial Park project only took 6 months from its start to its completion. Chairman Li Ling said that behind this, it is inseparable from the refined services of the Torch High tech Zone. From early project planning to bidding and construction management, the construction service team of Torch High tech Zone assisted us in promoting related work, and a series of services made us feel worry and effort free.         Chairman Li Ling stated that SAN-U Optronics plans to gradually launch production line relocation work starting from the second quarter of next year. The company will seize the opportunity for cross island development, actively integrate into the city's high-tech industry layout, and strive to become the main supplier of sensors in China. The SAN-U Optronics Industrial Park project is located in the Tong'an area of Tongxiang High tech New City. The project is planned to invest over 250 million yuan and is expected to achieve an annual output value of over 2 billion yuan after reaching its capacity. The total construction area of the project is approximately 48000 square meters, mainly consisting of two factory buildings and one office complex building. The industrial park will build a production workshop that integrates its existing production capacity of optoelectronic devices and optoelectronic components applied in the fields of data transmission and communication, and establish a design and development center and supporting infrastructure for 5G carrier network equipment optoelectronic devices, SiC series products above 1200V, sensing laser light sources, MEMS chip sealing and testing, and other production lines.
