Abstract:
Bipolar transistors and MOS transistors are formed in a common process. A semiconductor layer is arranged on an insulating layer. On a side of the bipolar transistors: an insulating region including the insulating layer is formed; openings are etched through the insulating region to delimit insulating walls; the openings are filled with first epitaxial portions; and the first epitaxial portions and a first region extending under the first epitaxial portions and under the insulating walls are doped. On the side of the bipolar transistors and on a side of the MOS transistors: gate structures are formed; second epitaxial portions are made; and the second epitaxial portions covering the first epitaxial portions are doped.

Claim (Index 9):
An integrated circuit, comprising:\n a substrate including a semiconductor layer arranged on an insulating layer covering a semiconductor substrate doped with a first conductivity type; a trench isolation separating a first region of the substrate from a second region of the substrate, wherein the second region does not include the semiconductor layer; wherein the substrate in the second region includes an opening extending through the insulating layer; first epitaxial material filling the opening to form a base of a bipolar transistor having a collector formed by at least a portion of said semiconductor substrate; a transistor gate extending over the semiconductor layer; second epitaxial material over the first epitaxial portion and over the semiconductor layer on each side of the transistor gate; wherein the second epitaxial material over the first epitaxial portion forms an emitter of the bipolar transistor and wherein the second epitaxial material on each side of the transistor gate form source and drain regions of a MOS transistor.
