Abstract

PURPOSE:To improve a current amplifying rate of an I<2>L element, by a method wherein, when the I<2>L element and a bipolar transistor are indivudually placed in island-shaped regions which are separated from each other, and most of carriers, poured into a base region, of which the I<2>L element consists, are supplied from a submerged emitter region of a high impurity density. CONSTITUTION:Two type N<+> submerged regions 23 are formed in a type P Si substrate, and a type N layer 21 is epitaxially grown on the whole surface including the regions 23. The layer 21 is separated into island-shaped layers 34 and 35 including each region 23 by means of a region 22. Type P regions 25 and 26 and a type N<+> region 27 positioned in the region 26 are formed in the one layer 34. An I<2>L element consists of the region 26, the island-shaped layer 34, and the region 25, and an inverse transistor consists of the region 23, the island-shaped layer 34, and the regions 25 and 27. A type P region 24 and an N<+> region 28 located therein are also formed in the island-shaped layer 35, and a bipolar type transistor consists of them.
