IT Home reported on January 2 that Sai Microelectronics issued a brief announcement on December 31, 2023: MEMS-OCS has achieved mass production.
On December 24, 2023, Beijing Sai Microelectronics Co., Ltd. issued an announcement on the start of mass production of its wholly-owned subsidiary, MEMS-OCS, which is manufactured by SILEX Microsystems AB for a customer using MEMS (Micro-electro-Mechanical Systems, that is, microelectromechanical systems, referred to as MEMS) process Switch, an abbreviation for Optical Link Switching Device), completed process and performance verification (the total time spent on process development and trial production was more than 7 years), and on December 22, 2023, the customer received a bulk purchase order, and Silex Sweden began commercial-scale mass production of MEMS-OCS.
According to reports, the MEMS-OCS is based on 8-inch MEMS process and design technology, complex and precise structure, is a set of micromirror arrays composed of a specified number of plane mirrors, 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, while reducing system cost and power consumption, can be widely used in data center networks, supercomputing system clusters and other scenarios.
IT Home found that on December 29, 2023, Beijing Saiwei Electronics Co., Ltd. issued an announcement on the verification and start trial production of its holding subsidiary MEMS-IMU, and a certain MEMS-IMU (Inertial Measurement Unit) manufactured by the holding subsidiary Celex Microsystem Technology (Beijing)** The abbreviation of Inertial Measurement Unit (i.e., Inertial Measurement Unit) was validated by the customer, and Celex Beijing received a purchase order from the customer to start the pilot production of the first batch of MEMS-IMU 8-inch wafers.
According to reports, IMU is the core of inertial measurement and positioning, and is a key device for measuring the three-axis attitude angle (or angular rate) and acceleration of an object. MEMS-IMU is manufactured based on MEMS process technology, which has the characteristics of small size, light weight and low energy consumption, and collects inertial information such as acceleration and angular velocity of the motion carrier in a tiny form, which can output high-precision three-dimensional position, velocity, attitude and other information in real time, and is used for attitude balance control, navigation and positioning, action execution and other links. Due to the semiconductor process, MEMS-IMUs can often also integrate the functions of multiple MEMS inertial sensors, and at the same time, have excellent environmental adaptability, and can be widely used in smartphones, wearable devices (including AR VR MR), unmanned systems, intelligent driving, humanoid robots, and other fields.
