We report on the first experimental observations of an anomalous increase in the resistance of a semiconductor-super conductor contact in the vicinity of the critical temperature Tc. The effect is found in lead-doped InSb thin films having inclusions of lead of 1-3 μm in diameter: The observed effect can be a model that explains similar resistance increase observed sometimes in the high Tc superconductors.
