IPC: H01L23/29
Filed: 1978-10-20
Abstract: PURPOSE: To prevent the cracks of a semiconductor element fixed on a substrate for radiation and the disconnection of conductors, by arraging elastic insulating materials around the flanks of the element, and by sealing the whole with resin.  
     CONSTITUTION: A square, ring-shaped weir 12 is mounted onto a radiator plate 11 in copper plated with silver, and its height is made lower than the thickness of a semiconductor element 15. The semiconductor element 15 that conductors 14 are connected onto an upper surface of a Si element piece 13 is fixed onto the radiator plate 11 surrounded by the weir 12 with lead-tin solder. Isoprene rubber 16 is installed between the weir and and the element, and the whole is coated with resin 17 for sealing. The conductors 14 are connected to lead frames 18 inserted and put into the resin layer 17. According to this constitution, stress parallel with the flanks applies to the flanks of the element piece 13 by the effect of heat, but can be moderated by the excellent, elastic action of the isoprene rubber 16, and impact force can also be lightened. Thus, the cracks of the whole element piece 13 are prevented, and the conductors are not disconnected because the uniform, thermal expansive force of the resin applies to the conductors.
