    摘要: The invention relates to the field of microelectronics, such as integrated circuits, and more particularly to compositions and methods of removing photoresists or other organic materials from the surfaces of substrates used in the fabrication of integrated circuits. In particular the present invention relates to amine-free stripping compositions comprising solvent and surfactant that can effectively remove organic materials without corroding the underlying substrate, and the invention also relates to methods for removing these organic materials with the novel stripping composition.

    摘要: Poly(hydroxystyrene) resins in which a portion of the hydroxyl groups are functionalized with t-butyloxycarbonyl groups ("t-Boc") tend to decompose during drying of the wet solid and on storage in the solid state. Solutions that are more stable than the solid material can be made from the wet freshly synthesized solid by dissolving the wet solid in a solvent that forms an azeotrope with water and then distilling the azeotrope of water and solvent from the solution until the solution contains less than about 1% by weight of water.
