The 피드백 제어기 (CPC-1) automatically adjusts to maintain a set pressure or flow rate in high purity, closed-loop chemical pumping systems to compensate for variables in wafer processes, such as opening/closing chamber valves or clogging filters. The controlled closed-loop system improves process repeatability, increases chip yields, and simplifies automation to save customers time and resources. It also eliminates the need for expensive pressure systems.
고순도 폐 회로 펌프 시스템
Capable of Temperatures up to 210°C, Dead-Head, and Suction lift! No metals, No O-rings, No Lubrication, No Rotating Parts, No Cooling Jackets!
The CPC-1 provides the world’s first high-purity, closed-loop system capable of generating suction lift and operating at temperatures of up to 210°C. Further, White Knight pumps and pulse dampeners used in the system do not contain metals, O-rings, lubrication, or rotating parts in the fluid path.
The CPC-1 simplifies process automation to save customers time and resources. It improves system reliability and repeatability, eliminates the need for expensive pressure systems, and allows for a complete ultra-high purity, closed-loop system that utilizes White Knight’s proven, non-metallic pneumatic pumps and pulse dampeners to eliminate contaminant risk and allow for temperatures up to 210°C as well as high suction lift.
