Abstract
A method of mounting and demounting a semiconductor wafer, in which a temperature dependent adhesive and curable joint is provided by an adhesive mixture between the semiconductor wafer and a carrier plate. The adhesive mixture contains a colophonium resin which is chemically modified and esterified. The cured joint is released with water again after polishing the semiconductor wafer. The adhesive mixture suitable for carrying out the method is this resin with an amine which saponifies the resin.
