Abstract
Vacuum-level problems in semiconductor process tools -- from leaks or contamination -- can significantly reduce product yield and tool availability if not detected quickly. Here we present a portable and compact plasma sensor which can monitor the fingerprint of effluent from the process chamber to the exhaust piping by optical emission spectroscopy. The device and tests to monitor and control semiconductor process are described. Further applications such as effluent treatment are tackled.
