High integration, High performance, rapid paced manufacturing processes for semiconductors depend mostly on gas-based systems.
The clean efficiency of these gas-based systems is said to be one of the factors for a major impact on the semiconductor industries future development.
The gas cylinders are the backbone of these systems, which are not able to achieve clean efficiency unless the gas cylinders are able to supply clean gas.
The SUMI-FINE series is a clean gas cylinder taking advantage of unique technology for a polished inner surface, therefore dealing with moisture, particles and other issues in response to a wide range of customer needs.
