Abstract

PURPOSE:To obtain a semiconductor integrated circuit in which the elements such as I<2>L and the high dielectric strength bipolar transistor featuring the different dielectric strength to each other coexist without impairing each characteristics. CONSTITUTION:Sb, As and the like are diffused selectively on the surface of P-type Si substrate 1 to obtain n<+>-type buried layer 21 and 22 featuring a high density, and n<->-type layer 3 is epitaxial-grown on the entire surface. Layer 21 and 22 become the high dielectric strength bipolar Jr formation region and the I<2>L formation region respectively. After this, Sb, As or the like are diffused selectively again only at the I<2>L region to obtain high-density n<+>-type buried layer 4, and then n<->-type layer 5 is epitaxial-grown. The phosphorus or the like is diffused selectively at the I<2>L region on the surface of layer 5 to obtain n-type layer 6 featuring higher density than layer 5, and then P<+>-type layer 7 reaching substrate 1 in depth is formed by diffusion.
