Subject: Problem wbnonmetal SNF 2009-07-24 18:41:53: wafer in bottom of right sulfuric bath
Message-ID: <mailman.824.1357939066.26053.wbnonmetal-pcs@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.
