"Science and technology is the primary productive force, and it is necessary to compete with neck-stuck technology." Dr. Sun Dongming, deputy to the National People's Congress, researcher of the Institute of Metal Research, Chinese Academy of Sciences, and one of the founders of Liaoning Lengxin Technology Co., Ltd. has started research on nanocarbon-based electronic devices. , has been conscientiously fulfilling his duties around these two sentences.


In mid-2021, the scientific and technological achievements of the Institute of Metal Research, Chinese Academy of Sciences, "the research and development and industrialization of micro-semiconductor refrigeration chips" were officially transferred to Liaoning Lengxin Technology Co., Ltd. One of the core technologies of 5G "stuck neck" - the problem of localized manufacturing technology of micro-semiconductor refrigeration chips.



Liaoning Lengxin Technology Co., Ltd. is a high-tech enterprise that provides active temperature control technology solutions for the field of semiconductor integrated circuits. It is mainly engaged in the research and development, production and sales of high-performance thermoelectric materials and micro-refrigeration chips, is the present domestic only has fully independent intellectual property rights and realize the production of Chinese enterprises.


The company is located in the International Industrial Park, Hunnan District, Shenyang City, Liaoning Province. It is a joint-stock company jointly funded by the People's Government of Hunnan District of Shenyang City, the Institute of Metal Research of the Chinese Academy of Sciences, Shenyang High-tech Development Investment Holding Group and the micro thermoelectric refrigeration chip research and development team. .

The company currently has more than 7,000 square meters of sites that meet the requirements of the chip production environment, and more than 1,000 square meters of "Hundred level" clean R&D laboratories. The production line includes large cutting machine, SMT machine, reflow welding, magnetron sputtering system and other advanced production equipment and R&D equipment. Also equipped with vibration test bench, impact test bench, hot and cold impact box and thermoelectric chip refrigeration performance tester and other precision inspection equipment.


The performance of the company's products has reached the international leading level of similar chips. Many of the company's stereotyped products have passed the technical verification of end-customer enterprises, providing high-quality products and technical services for flagship companies in the information industry. At the same time, the company has established stable cooperative relations with Shanghai Institute of Science and Technology, Chinese Academy of Sciences, Institute of Physics and Chemistry, Chinese Academy of Sciences, Chinese Academy of Sciences Microsatellite Innovation Research Institute, Tsinghua University, Northeastern University and other universities and research institutes. The company's core research and development team includes 1 academician of CAS, 1 national "Outstanding Youth", 1 national "Thousand Talents Plan", 1 national "Excellent Youth", 2 "One hundred Talents" of CAS, 2 "Hundred Talents" of Liaoning Province, 2 "High-level Leaders" of Shenyang City, 3 researchers of CAS, and more than 10 mobile experts. Make the company's product performance and technology update iteration ability always in the industry leader position.


The company's related research results have been reported by the Science Communication Center of the National Natural Science Foundation of China, Xinhua News Agency, Science and Technology Daily, and CCTV-10 "Into Science" and other news and scientific media, and have won wide attention and high evaluation from the industry and abroad.


One of the founders of the company - Dr. Tai Kaiping

Semiconductor refrigeration chips are the key core components for optical communication devices/modules to achieve precise temperature control. They are limited by space-limited efficient heat dissipation technology and have absolute exclusivity! It is the only solution for temperature control of 5G optical modules at present, and it is developing rapidly in the direction of high integration density, high COP, low power consumption, fast response, and high cooling flux! The products and technologies can also be applied in other product systems and industries, such as computing chips, photodetectors, PCR biomedical equipment, automatic driving and lidar, etc. It is currently an active cooling and temperature control technology widely used in integrated circuits.

The company has passed ISO9001 quality system certification, RoHS certification and Reach certification. The company was successfully awarded the Liaoning Provincial Micro-Refrigeration Chip Engineering Research Center of the Wholesale Reform Commission, and was selected as the Shenyang Xinqiao Innovation and Entrepreneurship Base and the vice-chairman unit of the Shenyang Xinqiao Innovation and Entrepreneurship Alliance. The company's key materials and device research projects in the thermal control technology of optoelectronic chips have been successfully selected into the fourth batch of directional projects in Liaoning Province's science and technology plan in 2021.

The company will always take "becoming the preferred supplier of micro-semiconductor refrigeration chips" as its corporate tenet, and will work hard to break international technical barriers, improve the independent manufacturing capacity of optoelectronic modules from the perspective of key core components, and promote the construction of new infrastructure such as 5G in my country, for technological innovation. Contribute to the high-quality development of China's economy!

Chinese core, to the world!
