Building on the company’s proven GF Series of MFCs with EtherCAT connectivity for high-speed communications, the newly enhanced GF125 MFC features embedded self-diagnostics that automatically detect sensor drift and valve leak-by to help minimize tool downtime and improve process yield. As a result, the enhanced GF125 can run leak and drift self-diagnostics without interrupting process flow steps or requiring any hardware changes, thereby improving process gas accuracy and wafer production throughput.
