After 7 years of successful development, Sai Microelectronics has now begun mass production of MEMS-OCS optical link switching devices

IT House News on January 2, Sai Microelectronics issued a brief announcement on December 31, 2023: MEMS-OCS achieves mass production.

On December 24, 2023, Beijing Sai Microelectronics Co., Ltd. issued an announcement about the launch of mass production of its wholly-owned subsidiary MEMS-OCS. Silex Microsystems AB, a wholly-owned subsidiary, manufactured an OCS (Optical Circuit Switch) for a customer using MEMS (Micro-Electro-Mechanical Systems) technology. Link switching device ) completed process and performance verification (the total time spent on process development and trial production was more than 7 years), and received a bulk purchase order from the customer on December 22, 2023. Silex of Sweden started Carry out commercial-scale mass production of MEMS-OCS.

According to reports, the MEMS-OCS is manufactured based on 8-inch MEMS technology and design technology. It has a complex and precise structure and is a set of plane mirrors made of a specified number. The micromirror array formed can be used to accurately adjust the refraction direction of the optical link, realize signal switching and two-way propagation between optical links, improve the overall performance and stability of the computing system, and reduce system cost and power consumption at the same time.

Can be widely used in data center networks, supercomputing system clusters and other scenarios.

IT Home query found that Beijing Sai Microelectronics Co., Ltd. issued an announcement on December 29, 2023 that its holding subsidiary MEMS-IMU passed verification and started trial production. A certain MEMS-IMU (abbreviation for

Inertial Measurement Unit, i.e. inertial measurement unit) manufactured by System Technology (Beijing) Co., Ltd. passed the customer verification, and Selex Beijing received the purchase order from the customer. Order, start small batch trial production of the first batch of MEMS-IMU 8-inch wafers.

According to reports,

IMU is the core of inertial measurement positioning and is used to measure the three-axis attitude angle (or angular rate) and acceleration of an object. Key device. MEMS-IMU is manufactured based on MEMS process technology and has the characteristics of small size, light weight and low energy consumption. It collects inertial information such as acceleration and angular velocity of moving carriers in a tiny form, and can output high-precision three-dimensional position, speed, attitude and other information in real time. , and used for posture balance control, navigation and positioning, action execution and other aspects. Because it is manufactured through semiconductor processes, MEMS-IMU can often integrate the functions of a variety of MEMS inertial sensors. It also has excellent environmental adaptability and can be widely used in smartphones and wearable devices (including AR / VR / MR ), unmanned systems, intelligent driving, humanoid robots and other fields.

The above is the detailed content of After 7 years of successful development, Sai Microelectronics has now begun mass production of MEMS-OCS optical link switching devices. For more information, please follow other related articles on the PHP Chinese website!
