OES Overview

Diagnosis of process conditions and anomaly detection is possible through optical spectrum analysis emitted from CVD and dry etching plasma chambers of semiconductor display processes. Our Optical Emission Spectroscopy (OES) system is a multi-channel OES system for real-time monitoring with real-time optical spectrum data acquisition and transmission of customized analysis data based on TCP / IP Interface, online facility condition monitoring, and process condition diagnosis.
