From mahnaz at stanford.edu Tue Nov 10 11:49:50 2009 From: mahnaz at stanford.edu (Mahnaz Mansourpour) Date: Tue, 10 Nov 2009 11:49:50 -0800 Subject: 220/ 7um update Message-ID: <4AF9C3DE.7080503@stanford.edu> I have to say that 7 um looks 10 fold better but still there are issues with the uniformity and speed boat. I have shown the wafers I ran this morning to Gary and Mario both. I did everything that I was suppose to do before running the wafers. Although I have to say that the issue is caused by viscosity of the resist combined with old track that does not have some of the features we like to have. I had some ideas and ran it by Gary and he likes to see if is doable. ( so he will make different recipe for me to test) I ran two different test this morning wafers with combination bake 100s @ 90 + 100s @ 115 thickness 71600A wafers with 200 second bake 71550 A all okay for now so please use it and report any issues on coral. mahnaz
