Abstract

A spin-on glass (SOG) depositing system includes a suck back (SB) valve arranged to receive SOG. The SOG depositing system further includes a SOG dispenser having a nozzle, the SOG dispenser coupled with the SB valve for receiving SOG. The SOG depositing system further includes a detector positioned to detect SOG outside the nozzle. The SOG depositing system further includes an SB valve controller coupled with the detector for receiving one or more signals from the detector and coupled with the SB valve for controlling operation of the SB valve, wherein the SB valve controller is configured to pause sensing by the detector based on the sensed amount of SOG outside the nozzle being outside at least one operating parameter.
