Pressure-Based Mass Flow Control Module CRITERION D507 Series (1.7MB)

"Recently, with the increase of application of a semiconductor device according to IoT, the latest semiconductor factories are focusing to minimize the downtime of the apparatus. Therefore, for the purpose of failure pre-detection of semiconductor tools and its components, the managed parameters of semiconductor process are increased, and its specification is getting tighter. In order to satisfy the required control criteria, the mass flow control module is required to have high-speed communication and failure pre-detecting function as well as flow rate accuracy and reproducibility, inlet pressure insensitivity performance. D507 series is lined up on D500 series to meet strict management at recent semiconductor factory."
