Does anybody know of a temporary trench-filling material other than water-soluble or latex-peelable solder masks? I need to fill a trench 0.012" deep by 0.012" wide by 1.900" long. The material must withstand solvent chemistries, have relatively low-outgassing properties (vacuum environment), and be removable at the end of our fabrication process. Any suggestions would be greatly appreciated. Eric Wong IBM San Jose 5600 Cottle Rd San Jose, CA 95193 [log in to unmask]
