Abstract:
Ein Verfahren zur Handhabung eines Produktsubstrats schließt das Verkleben eines Trägers mit dem Produktsubstrat ein. Eine Schicht aus einem permanenten Klebstoff wird auf eine Oberfläche des Trägers aufgebracht. Eine strukturierte Zwischenschicht wird vorgesehen. Der aufgebrachte permanente Klebstoff verbindet den Träger mit dem Produktsubstrat. Die strukturierte Zwischenschicht ist zwischen dem Produktsubstrat und dem Träger vorgesehen. Eine Oberfläche der strukturierten Zwischenschicht und eine Oberfläche des permanenten Klebstoffs befinden sich im direkten Kontakt mit einer Oberfläche des Produktsubstrats. Die strukturierte Zwischenschicht verringert die Haftfestigkeit zwischen dem Produktsubstrat und dem Träger.
