Abstract

Evaluation method for delamination strength of micro-sized materials has been developed using by FEM and measurement of load-displacement curve of micro-sized specimen. This evaluation method is applied to micro-sized cylindrical SU-8 specimens on Si substrate. The maximum shear stress between SU-8 and Si was analyzed with FEM. Fracture load required to delaminate the two materials was examined using a mechanical testing machine for micro-sized materials, which have been developed in our group. The delamination strength was determined from the maximum shear stress and the fracture load.
