On November 19, 2021, China's semiconductor chip test probe invisible champion company: SZHL announced that the company will issue no more than 24 million A shares to specific targets, and the total amount of funds raised will not exceed 700 million yuan.
It will invest in MEMS Process wafer test probe R&D and mass production project, substrate-level test probe R&D and mass production project and supplementary working capital.
In recent years, with the continuous development of foundry technology, lithography technology is constantly approaching physical limits, and the cycle of Moore's Law is gradually prolonged. The integrated circuit industry is about to enter the post-Moore era, but downstream industries have continuous requirements for chip performance. improve. Advanced semiconductor testing technology can improve the performance of the chip to a certain extent, and semiconductor testing equipment and key components are important guarantees for the advancement of semiconductor testing technology.
On the other hand, with the increasing wiring density of printed circuit boards (Printed Circuit Boards), the electrode spacing of high-end substrates in the current international market can reach 0.045mm, and the corresponding test probe diameter needs to reach 0.02mm. , And the future needs to develop in a smaller direction. At the same time, the gold-plated surface of high-end substrates requires no traces and requires precise control of probe strength and contact impedance. Therefore, traceless detection and precise positioning are also technical problems faced by high-end substrate testing.
In order to solve the aforementioned problems, substrate testing companies have introduced customized linear probes for substrate testing, which can effectively solve the problems of inaccurate positioning, needle mark damage and short probe life, while also having good contact impedance stability. The above-mentioned advantages of customized linear probes make it the future development direction of substrate probes.
China's chip industry is developing rapidly. The localization of semiconductor chip manufacturing will drive the localization of corresponding supporting industries such as packaging and testing.
In the field of semiconductor testing, SZHL is an early Chinese company that participated in the global high-end market competition. It has worked in the MEMS micro-manufacturing and probe industry for many years and has accumulated a certain amount of industry experience and technical reserves. The company's semiconductor chip testing probe products have been applied in mainstream semiconductor testing equipment such as TERADYNE and ADVANTEST.
The company plans to invest in the R&D and production of MEMS process wafer test probes and substrate-level test probes to fill the gaps in related fields in China.
This new investment project will help China's semiconductor testing related fields to break through the technology monopoly of foreign companies, promote the development of China's semiconductor testing related probe industry, promote the improvement of the technical level and product quality of Chinese companies in this field, and help China's high-end Localization of semiconductor components.
