Although be careful - cyanoacrylate needs water to cure. Ussually it gets enough moisture from the air. If you are bonding two large areas that are smooth and non-porous (like silicon wafers!), you may find that the stuff in the middle remains liquid. Not that it isn't worth a try, of course!

It works well in TMAH and EDP. It can be dissolved it in acetone, though I've been bonding the front of wafers to chrome coated glass and then etching the chrome to release. Good luck, mike >>> skk9@cornell.edu 11/02/02 10:32AM >>> Are there materials that can used for wafer bonding that doesn't get etched/stripped in KOH bath? I've already tried Apiezon black wax, crystal bond, SU-8 (not fully crossed), but they all seems to not work quite well. I would appreciate any advice.
