Fwd to: Jesse D Fowler I use Chlorobenzene (4-5 minutes) after S1813 exposure and before development just like you have suggested. It looks like the Chlorobenzene I used was contaminated because I repeated the experiment with a new batch of Chlorobenzene and it seemed ok. Another problem is that there is no good adhesion of gold (evaporated gold around 500 nm) on the silicon surface. maybe Titanium first?
