A semiconductor chip is mounted on a die pad of a lead-frame, and the semiconductor chip mounted on the die pad is sealed in a plastic package; a side surface of the semiconductor chip and an exposed upper surface and a side surface of the die pad are covered with an organic stress relaxation layer so as to reduce a thermal stress due to the difference in thermal expansion coefficient between the semiconductor chip and the die pad, thereby presenting the plastic package from a crack.
