Abstract: PURPOSE:To prevent the damage of glass cracks, etc. without damaging electric characteristics and thus improve the manufacturing yield by forming a glass passivation film at the region except an inside region not including the P-N junction of a guard ring layer. CONSTITUTION:Except the inside regions A and B not including the P-N junctions of the P-layers 12, 13 (guard ring), the glass passivation film 17 is adhesion- formed on the surface of an N-layer 11 form the P-N junction 15 at the outer periphery of the P-layer 14 to the P-N junction at that 16 of the P-layer 13. Since said film 17 is severed at the surface part of each inside region A and B of the P-layers 12 and 13, the area becomes much narrow, and accordingly the rate of the generation of glass cracks in case of applying mechanical and thermal loads decreases. Because of the adhesion-formation of said film 17 on the surface of each P-N junction (including a depletion layer region), the electrical characteristic does not deteriorate.

Abstract: PURPOSE: To avoid, in a resin seal type semiconductor device having a junction coating resin layer, deterioration attributable to invasion by water or the like through eliminating the gap at the boundary by imparting a sufficient flexibility to the junction coating resin layer.  
     CONSTITUTION: A junction coating resin 16 coating a semiconductor device 4 together with a frame disc 3 exhibits, after a curing, a moderate adhesion and viscosity (150W250/5sec as measured by needle depth meter). After adhesion of the resin 16, a transfer molding is effected with a sealing resin such as an epoxy resin 2 to form an envelope. Since the resin 16 is pressed by the sealing resin, no gap is formed at the boundary between the resin 16 and the resin 2, so that the invasion of water or the like is prevented to avoid deterioration of the device.
