On August 31, the 14th Semiconductor Equipment Materials and Core Components Exhibition (CSEAC 2026) officially opened in the Taihu Lake International Expo Center in Wuxi. With the theme of "Strengthening China's Core and Embracing the Core World", the exhibition covers a total area of more than 70000 square meters and spans eight exhibition halls, attracting 1400 semiconductor enterprises from home and abroad across the whole industry chain to participate in the exhibition. On the first day of the opening, the scene was crowded, and the atmosphere of negotiation and exchange in each exhibition area was warm.
Multi Field Low Temperature Technology (Beijing) Co., LtdDuochang Technology (hereinafter referred to as "Duochang Technology") is an enterprise that focuses on the research and development, sales, and provision of overall solutions for ultra precision motion control, positioning measurement technology, and products at the nanoscale and sub nanoscale in the entire environment. It specializes in semiconductor manufacturing, precision optics, and high-end scienceinstrumentCarry out related technology research and development in various fields.
As a national key "little giant" enterprise specializing in precision, innovation, and new technologies, Duochang Technology showcased three core products at the exhibition, focusing on the precision control needs of semiconductor manufacturing and bringing high-precision solutions adapted to extreme environments. At the exhibition site, professional visitors came and went in front of multiple low-temperature booths, and multiple technology teams engaged in in-depth exchanges with visiting audiences.
Nano scale piezoelectric ceramic displacement table
Nano scale piezoelectric ceramic displacement table
The nanoscale piezoelectric ceramic displacement table covers a full range of specifications including linear, offset, rotary, multi axis series/parallel, and sub nanometer high-speed scanning. It can achieve high-precision motion control at the nanoscale/sub nanometer level, support special environments such as ultra-high vacuum, completely non-magnetic, and extremely low temperature, and can meet customized requirements for large loads, long strokes, and high speeds. It can be widely used in core processes such as semiconductor lithography, bonding, measurement, and detection.
Capacitive position sensor
Capacitive position sensor
The capacitive position sensor of Multi Field Technology has sub nanometer spatial resolution, supports 50kSa/s high-speed data acquisition and high-speed communication, with a range coverage of 0.2-3mm, and provides multiple probe forms to choose from. It is also suitable for special working environments such as ultra-high vacuum, completely non-magnetic, and extremely low temperature, and can accurately meet the precise measurement and positioning needs of semiconductor bonding, measurement, and detection.
Multi channel laser interferometer
Multi channel laser interferometer
This multi-channel laser interferometer can achieve picometer level high-speed ranging, with a working distance coverage of 0 to 10 meters and a maximum target speed of 3.8 m/s. A single device is equipped with 3 measurement channels, which can independently measure 3 linear degrees of freedom and provide multiple probe forms to choose from. This device supports special usage environments such as ultra-high vacuum and complete demagnetization, and can be widely used in precision positioning and real-time position feedback in semiconductor manufacturing.
At the CSEAC 2026 site, multiple technologies relied on core precision component products and engaged in in-depth communication and docking with upstream and downstream partners in the industry chain. This not only demonstrated the company's technological accumulation in the field of ultra precision motion control, but also built a bridge for subsequent industrial collaboration, helping the domestic semiconductor industry to continuously break through and upgrade in the core component link.
