The note is dated Nov. 1. There is only one dump rinser on wbnitride. Where should I do the dump rinse after nitride etch? I will hate to do it at wbnonmetal with H3PO4 dripping during the journey. If the dump rinser is contaminated, what about H3PO4 pot and the spin dryer? I do not see any problem reported on Coral. Does it mean that problem has been taken care of? Users have not been informed about contamination/cleaning. Such instances have become frequent recently.

Nitride wet etch is not possible without it. I drained the H3PO4 pot but could not rinse it. - Amol
