From mahnaz at stanford.edu Wed May 18 13:20:53 2011 From: mahnaz at stanford.edu (Mahnaz Mansourpour) Date: Wed, 18 May 2011 13:20:53 -0700 Subject: wec is slightly off Message-ID: <4DD42A25.2080400@stanford.edu> hello all, I thought to let you know that the last few times that we have tested the system, I did not get a good result. Mario and Gary worked on it and shot a wafer yesterday which i looked at it this morning. The wafer they shot looked perfect in the center and left and right and okay on top and flat area. i thought to run one more wafer from the same batch of wafers which I did not get that result. After adjusting some of the setting, I ran out of wafers . I decided to put the stetting back to original as it gave me the best result. If you expose wafers check the top and flat area and please comment on coral will be helpful. I will continue this afternoon. mahnaz
