    Abstract: A bipolar transistor in accordance with the invention includes a polysilicon base contact (607A) which is self-aligned with a polysilicon emitter (303). The polysilicon emitter is formed from a first polysilicon layer overlying an intrinsic base region (502) in a substrate (201). An extrinsic base (504) in the substrate is in contact with the intrinsic base and is self-aligned with a spacer (406) adjacent to the emitter. The polysilicon base contact is formed from a second polysilicon layer (407) in contact with the extrinsic base and overlying the emitter. A second sidewall spacer (508) is formed on the second polysilicon layer on step caused by the emitter. A protective layer (509, 510) formed on portions of the second polysilicon layer protects the base contact when the second spacer and the underlying portion of the second polysilicon layer are removed. The separation between the polysilicon base contact and the polysilicon emitter is controlled by the thickness the second polysilicon layer and the thickness of the spacers so that the base contact is self-aligned with a fixed separation from the emitter. Layer and spacer thicknesses define separation between the emitter and the base contact and permit sub-micron active regions in the substrate.

    Abstract: A truly complementary bipolar transistor structure and a combined bipolar and CMOS transistor structure are disclosed, each including a silicide layer formed upon a substrate that acts as an extrinsic base and gate. Optionally, a layer of polysilicon can be formed between the silicide layer and the substrate. An oxide layer (LTO) is formed or deposited over the silicide layer by chemical vapor deposition (CVD). Selected regions are defined and etched using a photoresist layer. Subsequent steps of implanting, etching and metalization are performed to produce transistors with reduced gate and extrinsic base resistances. Polysilicon may be used, instead of metal, as a contact in one embodiment of the invention.
