Abstract
Transfer tapes include a releasing substrate and an adhesive layer adjacent to the surface of the releasing substrate. The adhesive layer includes a at least one siloxane-based copolymer, and at least one siloxane tackifying resin. The adhesive layer is a pressure sensitive adhesive at room temperature and is convertible into a ceramic-like layer by bake-out at a temperature of from 100-500°.
