The Biological Indicators of COVID-19 Characteristic Detection Chip Jointly Developed by XMC and Liangzhun (Shanghai) have been Successfully Verified

On July 3, 2020, Wuhan Xinxin Semiconductor Manufacturing Co., Ltd. (hereinafter referred to as "XMC"), a leading semiconductor manufacturing company, announced that the biological indicators of COVID-19 characteristic detection chip jointly developed and produced by XMC, Liangzhun (Shanghai) Industrial Co., Ltd. (hereinafter referred to as "Liangzhun (Shanghai)") and Huazhong University of Science and Technology had been successfully verified. The chip can be used for a variety of miniaturized, lightweight, non-invasive and portable detecting instruments in communities and families. Compared with the kits currently in use, these detecting instruments are easier to operate, and their detection results are more accurate and can be obtained more quickly. The project team will proceed with the clinical test research of the COVID-19 live virus.

Based on the ultra-high sensitivity Nano SPR (Nano Surface Plasmon Resonance) optical sensing chip technology exclusively owned by Liangzhun, XMC produces array structure wafers efficiently for Liangzhun relying on its own mature 55nm technology platform and stable and reliable manufacturing capabilities. Compared with the traditional two-dimensional substrate chip, the new generation Nano SPR chip of Liangzhun can collect signal data from multiple dimensions, amplify the signal more than one thousand times, and obtain higher detection sensitivity and lower detection limit of molecular concentration. At the same time, it no longer needs the traditional complex optical path system to capture weak signals, which greatly reduces the cost of the application.

"We started this collaboration with XMC when the COVID-19 epidemic began to spread. It only took one month from the new technology development to the sample delivery, and all the biological indicators of the chip were tested to meet the design requirements of Liangzhun. That was the result of XMC's efficient and collaborative R&D system, stable and reliable manufacturing process and fast and flexible delivery capability. We are very pleased with our continued and close relationship with XMC. In the future, we will continue to deepen our partnership with XMC and keep on introducing more intelligent and cutting-edge biomedical testing products and solutions to benefit the society and millions of families." Said Xu Hao, Chairman of Liangzhun (Shanghai).

"We are very pleased with the achievements of this cooperation between XMC and Liangzhun." Mr. Sun Peng, Vice President of Operations of XMC, said, "The Nano SPR technology mastered by Liangzhun is the world's top platform-level technology. XMC was able to maintain close communication and cooperation with Liangzhun during the worst of the COVID-19 epidemic, actively deploy R&D personnel to support the development of the new process, and successfully deliver Nano SPR optical chips in a short period of time with high quality. That was another important verification of our mature, stable and customizable 55nm process platform. It is really exciting that this product will soon contribute to the fight against the epidemic in China and around the world. In the future, we will deepen and expand our specialty process platforms and continue to strive to provide differentiated and competitive products and solutions to our global customers."
