Eastern Crystal Source, Worldlink and 14 other companies have changed their status in the Shanghai Stock Exchange IPO review to "accepted".

On June 30, Oriental Crystal, Seviton, Qingke Biology, Huihe Medical, Yimiao Biology, Biyun Tian, Huake Precision, Weian Shares, Xinmai Machinery, Shenzhou Shares, Shanghai Yinguang, Xihe Technology, Mifei Technology, Luwen Instruments, and other 14 companies' IPO review status changed to "accepted" by the Shanghai Stock Exchange. Among them, Qingke Biology is a nationally recognized new "small giant" enterprise focusing on the field of synthetic biology, with the strategic goal of creating a "world-class gene factory". Relying on independently developed key reagents, key vectors, and synthetic equipment, deeply integrating "AI + molecular intelligence manufacturing" technology, it provides efficient and high-quality gene synthesis and gene sequencing services and related products for basic science, cutting-edge technology research, and industrialization in various fields such as biomedicine, bio-manufacturing, agriculture, food, and environment. Luwen Instruments is dedicated to providing advanced equipment and process solutions for the integrated circuit manufacturing industry, focusing on the research, development, production, and sales of semiconductor front-end equipment since its establishment. Holding a strategy of differentiated development from domestic competitors, with independently developed unique technology as the core, it has formed a multi-category product matrix centered on ion beam equipment and inductively coupled plasma (ICP) plasma etching equipment, supplemented by chemical vapor deposition equipment and gas phase decomposition metal impurity collection equipment. The company's products are widely used in advanced logic and memory wafer plants, specialty process power wafer plants, and optical display plants. Seviton is a nationally recognized new enterprise specializing in the research and development of optoelectronic devices and sensors, with main products including optoelectronic integrated devices and components, and strong electromagnetic environment fiber optic current sensors. Seviton's main product, the Y waveguide modulator, is the core device for high-precision angular velocity measurement in fiber optic gyroscopes, widely used in the inertial navigation systems of sea, land, air, and aerospace military and civilian fields. The strong electromagnetic environment fiber optic current sensor is a high-precision current measurement equipment based on the Faraday magneto-optic effect, with strong anti-electromagnetic interference ability, mainly used for high-voltage DC power transmission, controllable nuclear fusion devices, and large-scale aluminum electrolysis cells in extreme strong electromagnetic field scenarios. Xihe Technology focuses on the research and commercialization of silicon photonics integration technology, with its main product being high-performance silicon photonic integrated chips, covering speeds of 400G, 800G, and 1.6T, and has been widely applied in AI clusters and large-scale data centers. Weian Shares is a comprehensive solution provider focusing on circuit protection and power control, mainly engaged in the research, development, production, and sales of electronic components, power semiconductor discrete devices, and analog integrated circuits. The company's main business products are divided into two categories: circuit protection products and power control products, which are the two core functional components of electronic devices. Both play a role in ensuring the safety, reliability, and efficiency of products and are widely used in important sectors of the national economy such as industry and the Internet of Things, consumer electronics, new energy, network communications, and automotive industries.
