Abstract
PURPOSE:To realize the increase of working speed and the elevation of breakdown strength simultaneously by substantially thinning the thickness of an epitaxial layer section through rediffusion in an IIL section and using approximately the whole thickness of the epitaxial layer in a linear transistor section. CONSTITUTION:A P-type epitaxial layer 22 is formed onto a substrate 21, and an N-type epitaxial layer 23 is shaped onto the layer 22. An N<+> type buried layer 24 is formed to the surface of the substrate 21 so as to share the borders with the layer 23, penetrating the layer 22, an N<+> type buried layer 26 is shaped to the surface of the layer 22, and a linear transistor 25 is formed to the surface of the layer 23 in a region in which only the buried layer 24 is shaped. An IIL 27 is formed to the surface of the layer 23 in a region in which the buried layer 26 is shaped. Accordingly, the thickness of the epitaxial layer section is thinned substantially by rediffusion in the upward direction of the layer 26 in the IIL 27, and approximately the whole thickness of the layer 23 can be used in the linear transistor 25.
