Hi all, Does anybody know if butanol will remove Shipley 1800 Resists? My inclination tells me that most organic solvents will do it. I am actually trying to spin SOG on top of patterned resist but unfortunately the SOG I have now uses acetone as a solvent. I have found some SOG that only uses butanol. Any suggestions? Many thanks in advance for your help! Brian Fung Photonics Group Dept. of Electrical and Computer Engineering University of Toronto
