On August 10, SZMX Microelectronics Technology Group successfully IPO, the company's initial public offering of 13.3 million A shares, the issue price of 62.67 yuan / share.
SZMX is a semiconductor chip design company focusing on MEMS sensor R&D and manufacturing. It can be said that SZMX is the first MEMS stock in China.
After years of technology accumulation and R&D investment, SZMX has independent R&D capabilities and core technologies in the existing MEMS sensor chip design, wafer manufacturing, packaging and testing. At the same time, it can independently design to provide signal conversion and processing for MEMS sensor chips. Or drive function ASIC chip, and realize the localization of the whole production link of MEMS sensor.
With its excellent technical strength, the MEMS sensor products independently developed by SZMX have been recognized by customers such as Huawei, Transsion, Xiaomi, Baidu, Lenovo, Sony, LG, Lexin Medical, and Jiu'an Medical, and are widely used in smartphones and tablet computers. , Notebook computers, wearable devices, smart homes and other consumer electronic products, and gradually expand their applications in the automotive and medical fields.
In the field of MEMS microphones, SZMX's market share has been among the highest in the world. According to statistics from IHSMarkit, SZMX's MEMS microphone shipments ranked sixth in the world in 2016, fifth in the world in 2017, and fourth in the world in 2018.
As a star enterprise in China's MEMS field, SZMX's growth process is actually not easy.
At the beginning of the company's establishment in September 2007, Chinese wafer manufacturing companies and packaging companies generally lacked a professional MEMS product production system. After more than ten years of R&D investment, SZMX has completed the basic R&D work and core technology accumulation of MEMS product chip design, wafer manufacturing, packaging and testing, and helped domestic semiconductor manufacturing such as SMIC, China Resources and Huatian Technology The manufacturer has developed a professional MEMS wafer manufacturing and packaging test process, realizing the localization of all production links.
SZMX was forced to form a complete set of processes and R&D models at the beginning of its business, and has now become the company's core competitiveness.
"We are not afraid of being blocked by competitors' technology. From testing, materials to process, the company has accumulated technology and experience in all aspects." SZMX CTO Li Gang said that as a pioneer in China's MEMS industry, the company has independent R&D and design of MEMS sensor chips. Capability, has also accumulated OCLGA packaging technology, pressure sensor SENSA process, inertial sensor WLCSP packaging technology and other advanced technology processes in wafer manufacturing, packaging and testing, and deeply participated in the development of MEMS process for Chinese semiconductor manufacturers.
At present, the main suppliers of the company's wafers are SMIC, SMIC Shaoxing and China Resources Shanghua, and the packaging foundries are mainly Huatian Technology. "The localized production system ensures the stable supply of the company's MEMS sensor products, continuously improves the company's product performance and cost-effective advantages, can respond to the needs of domestic customers in a timely manner, and achieve rapid product updates and upgrades through in-depth cooperation with local suppliers. "The company stated in the prospectus.
Mr. Li Gang once said: "What we are most proud of is SZMX's contribution to the localization of the entire MEMS industry chain. The development of SZMX is the representative and epitome of the development of the domestic MEMS industry."
After cultivating MEMS technology for more than ten years, SZMX has accumulated its own core technology in chip manufacturing, packaging and testing of various product lines, which will not only lay a solid industrial foundation for the company to compete with domestic and foreign manufacturers in the future. , Also built a very deep moat.
As of December 31, 2019, SZMX has a total of 38 domestic and foreign invention patents, 19 utility model patents, 32 domestic and foreign invention patents and 24 utility model patents under application. The MEMS microphone products independently developed and produced by the company relying on core technology are at the advanced level in the industry in terms of product size, sensitivity, sensitivity tolerance and other indicators, and are the first in the industry to introduce the smallest size commercial three-axis accelerometer produced by core technology.
SZMX has actively participated in and completed the national or provincial scientific research projects: In 2014, it participated in the completion of the National 863 Program "CMOS-MEMS Integrated Microphone" project; in 2015, it completed the provincial scientific and technological innovation and achievement transformation special project "New MEMS digital acoustic sensor" R&D and industrialization"; In 2017, the provincial industrial and information industry transformation and upgrading special project "R&D and industrialization of low-power IIS digital output MEMS acoustic sensors" was completed.
SZMX successively won the "Top Ten Chinese MEMS Design Company Brands in 2013", the 2016 and 2017 Greater China IC Design Achievement Awards, and the China Semiconductor Industry Association 2016 and 2018 "Top Ten Chinese Semiconductor MEMS Companies". The company was also selected as "EE Times Silicon 60: 2015 Startups to Watch" published by EE Times, a world-renowned electronic product journal, in 2015 (60 noteworthy startups to watch worldwide).
