Plasma arcing sensor

摘要

A plasma arcing sensor is used to increase the frequency of plasma arcing by way of neutralization of positive charges and negative charges. When the plasma arcing can be predicted, the process parameters to prevent from the plasma arcing can be carried out. The plasma arcing sensor comprises a top conductive layer formed over a substrate. A conductive layer is disposed between the top conductive layer and the wafer where the conductive layer and the top conductive layer are electrically isolated with dielectrics.
