[Problem]

To provide such a composition for producing a sacrifice layer as has excellent properties in both heat resistance and storage stability, and also to provide a process for producing a semiconductor device using the composition.

[Solution]

Disclosed is a composition for producing a sacrifice layer. The composition comprises a solvent and a polymer having a repeating unit containing a nitrogen atom with a lone pair, and contains particular transition metals only in a very low content. Also disclosed is a process using the composition as a sacrificial material for producing a semiconductor device comprising a porous material.

A resin is provided for selectively binding to perchloride and related anions (e.g., TcO.sub.4.sup.−, ReO.sub.4.sup.− and I.sup.−) in aqueous solution. The resin may take the form of microparticles or beads. The beads are prepared by cross-linking macromolecules such as hyperbranched PEI, and quaternizing the amines with hydrocarbon substituents.
