Dear wbgen users:

 The Teflon cassette (half) for "clean" KOH etching with on red button 
is missing. If someone borrowed it, please return it. For now, there is 
one single wafer dipper marked with one red button available for the 
"clean" KOH etch.
And please use the cassettes with two red buttons only for "clean" TMAH 
etching.

Uli
