Abstract: PURPOSE:To form a transistor separately from a substrate by forming the collector of the transistor of the same conductive type buried layer as the substrate and providing a reverse conductive type buried layer for isolating the buried layer from the substrate. CONSTITUTION:A transistor having a p<+> type collector region (buried layer) 51, a p<+>type emitter region 13 and an n type base region between both regions 51 and 13, is formed in a diode connection in such a manner that the collector contacting region 12 and the base contacting region 9 are shortcircuitted. On the other hand, a transistor having a p<+> type collector region 52, a p<+> type emitter region 14 and an n type base region between both the regions 52 and 14, is formed in such a manner that the base contacting region 9 is commonly used with that of the previous transistor. Because both transistors are formed on the same p type silicon substrate 1, and are provided with n<+> type buried layer 3 for isolating the collector region 51 from the substrate 1, both buried layers 3, 51 are shortcircuitted by external wires, thereby preventing the increase in the junction capacity and the decrease in the withstand voltage.
