Improvement of particle outbreak for chamber wall deterioration

We used fault detect and classification (FDC) application to collect sensor's data of tool. The origin of particles is specified by correlating the data with plasma parameters. We proved particles were caused by the deterioration of chamber wall. The deterioration is the coat of Al alumilite pe...

Description
Summary:We used fault detect and classification (FDC) application to collect sensor's data of tool. The origin of particles is specified by correlating the data with plasma parameters. We proved particles were caused by the deterioration of chamber wall. The deterioration is the coat of Al alumilite peels off from chamber wall. After recoating the coat of Al alumilite on chamber wall, the outbreak of particles reduced.
