Hot embossing is an easy method for the reproduction of microstructures. Under vacuum, a moulding tool is pressed into a heated thermoplastic polymer (PMMA for instance).  For subsequent electroforming of metallic structures, the residual polymer layer that inevitably remains between substrate and molding tool has to be removed. The PlasmaProRIE is a highly suitable tool for such residual removal. An oxygen plasma is used.
