6.4.5. Stress Distribution during Demolding of Structures

6.4.5.1. Demolding of Ideal, Vertical Structures

As described in the section above, critical contact stress will result from shrinkage when switching from dwell pressure to velocity-controlled demolding. In this state, adhesion and the highest possible friction between substrate plate and mold can reduce shrinkage. However, shrinkage that cannot be avoided completely also results in stress inside the microstructures, which may be higher than the yield stress of the material at demolding temperature. This may give rise to the deformation or damage of microstructures. The microstructures located at the edge are especially at risk.
