Title: Sacrificial polymer compositions including polycarbonates having repeat units derived from stereospecific polycyclic 2,3-diol monomers

Abstract: Embodiments according to the present invention relate to sacrificial polymer compositions that include polycarbonate polymers having repeat units derived from stereospecific polycyclic 2,3-diol monomers. The sacrificial polymer compositions also include an acid generator that is selected from at least one photoacid generator and/or at least one thermal acid generator. In addition, embodiments according to the present invention relate to a method of forming a structure that includes a three-dimensional space interposed between a substrate and an overcoat layer, and a method of temporarily bonding first and second substrates together, which make use of the polycarbonate polymers.
