Abstract:
A PNP transistor is manufactured in parallel with the manufacture of NPN, NMOS, and PMOS transistors. A first semiconductor layer is deposited on a P-type doped semiconductor substrate and divided into first, second, and third regions, with the third region forming the base. An insulating well is deeply implanted into the substrate. First and second third wells, respectively of N-type and P-type are formed to extend between the second region and third region and the insulating well. A third well of P-type is formed below the third region to provide the collector. Insulating layers are deposited over the third region and patterned to form an opening. Epitaxial growth of a second P-type doped semiconductor layer is performed in the opening to provide the emitter.

Claim (Index 5):
An integrated circuit NPN-type bipolar transistor, comprising:\n a collector formed by an N-type doped well that is laterally delimited by a shallow trench isolation; a base formed by an epitaxial P-type doped region in contact with a top of said N-type doped well, said epitaxial P-type doped region having an upper surface; an extrinsic base formed by a P-type doped polysilicon layer extending over the shallow trench isolation and in contact with the upper surface of the epitaxial P-type doped region, the P-type doped polysilicon layer including an opening over the upper surface of the epitaxial P-type doped region; spacers protecting lateral surfaces of the opening; an emitter formed by an epitaxial N-type region that includes a first portion that extends through an opening in the spacers to contact the upper surface of the epitaxial P-type doped region and a second portion that is laterally delimited by the spacers; wherein the extrinsic base includes, laterally offset from the emitter and spacers, a base contact surface.
