We developed a new method for consistently evaluating adhesive strength over a wide range of shapes and load conditions. This method is based on the finite element approach and places "energy release elements (EREs)" (which mathematically represent the energy release due to debonding) between the interface of two jointed materials. By using this method to calculate the shear debonding strength of a photoresist, we show that the calculated strength agrees well with the shear-test-measured strength over all line widths. Furthermore, we apply this method to estimate debonding temperature of joints made from resin and steel. This estimated temperature agrees well enough for practical use with those measured by Terasaki et al. over all sizes and shapes of test specimens. These agreement shows that the new method can be widely applied for estimating adhesive strength.
