Article: Study on squeezing flow during nonisothermal embossing of polymer microstructures.

INTRODUCTION

Polymer microfabrication methods are becoming increasingly important as low-cost alternatives to silicon- or glass-based microfabrication technologies. The hot embossing technique [1] is a flexible, cost-effective microfabrication method for polymer microstructures. It uses the replication of a micromachined embossing master to generate microstructures on a polymer substrate. The hot embossing process involves several sequential steps. First, a preheated thermoplastic film/sheet is placed between two heated mold platens at a temperature above the softening temperature of the polymer. The elevated mold temperature is considered necessary for pattern ...
