We will solve the issues related to the deterioration of defect rates caused by fine particles and the cleaning of manufacturing sites. The particle visualization system developed by Shin Nippon Air Technologies, under the ViEST brand, combines a uniquely developed ultra-sensitive camera and light source to visualize fine particles in clean rooms and equipment. It can capture their behavior in real-time while also quantifying particle information, making it a world-class visualization system. Currently, we are expanding the sale of systems and tools, as well as contract technical services utilizing these technologies, both domestically and internationally. We have particularly rich experience in the semiconductor industry and clean room applications. The following are some examples of applications, but by using our technology, we can strongly promote solutions to various issues such as the deterioration of defect rates due to fine foreign substances, visualization of clean airflow, and cleaning of the site. - Visualization investigation of fine particles and airflow in the manufacturing line and environmental improvement - Promotion of cleaning within manufacturing equipment and environments - Cleanliness evaluation of various equipment performance - Improvement of yield and quality degradation caused by contamination issues - Support for research and development requiring visualization of fine particles and airflow - Evaluation of particle generation from products.
