Title: Semiconductor device
Inventor: OGAWA TOSHIO
IPC: H01L21/331
Filed: 1984-12-28
Abstract: PURPOSE:To realize a more reliable withstand voltage feature for a bevel surface and to improve workability in a passivation film forming process by a method wherein a bevel surface is so treated that one of the main faces of a thermal shock plate is caused not to be exposed with at least a solder material layer retained thereon. CONSTITUTION:A semiconductor substrate 1 is provided with a P-N junction between a P-type semiconductor 1b and N-type semiconductor 1a and with a bevel surface 6, and adhers to a thermal shock plate 3 with the intermediary of a solder material layer 2. In a process of working on the bevel surface 6, the solder material layer 2 of Al or the like is retained so that one of the main faces of the thermal shock plate 3 may remain unexposed. This prevents a portion, for example molybdenum, of the thermal shock plate 3, subjected to etching simultaneously with the crush layer of the bevel surface 6 from returning to the bevel surface 6 to cause an inferior with stand voltage capability. When a portion of the semiconductor substrate is retained after a process of working on the bevel, a suitable geometry should be chosen for the retained substrate so that silicon rubber or the like used for the passivation of the bevel surface may be prevented from flowing downward, which facilitates the passivation process.
