Problem wbnonmetal SNF 2009-07-24 18:41:53: wafer in bottom of right sulfuric bath

[mmessana at snf.stanford.edu]

realized that earlier today may have lost a wafer that floated up during resist strip.  using a wafer as a mirror, there appears to be a wafer at the bottom which I'm assuming is the wafer I lost somewhere along the way.  it's only silicon and oxide, so no weird materials for anyone concerned.
