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 1):
An integrated circuit PNP-type bipolar transistor, comprising:\n a collector formed by a P-type doped well within a P-type doped substrate; a base formed by an epitaxial N-type doped region in contact with a top of said P-type doped well, said epitaxial N-type doped region having an upper surface; an emitter formed by an epitaxial P-type region that includes a first portion that extends below said upper surface and a second portion that is raised above said upper surface; spacers protecting lateral surfaces of the second portion of the epitaxial P-type region; wherein the base includes, laterally offset from the emitter and spacers, a base contact region formed by a more heavily doped N-type region of the epitaxial N-type doped region.
