The invention relates to a bipolar transistor and a method for producing same. The aim of the invention is to provide a bipolar transistor and a method for producing same, which during the use of a single-process poly-silicon technology with differential epitaxis for the production of bases overcomes the disadvantages of conventional systems, so as notably further to improve the high-speed properties of a bipolar transistor, provide the most conductive connections possible between the metal contacts and the active (internal) transistor region as well as a minimized passive transistor surface, while at the same time avoiding greater process complexity and increased contact resistances. To this end a surface relief is produced in the active emitter region by a wet-chemical process. A single-process poly-silicon bipolar transistor having a base produced by epitaxis in accordance with the invention permits a reduction in external base resistance without causing a deterioration in emitter properties. Because the internal and external base regions are deposited continuously no interface problems arise during connection of the base. Base-collector capacity can also be lowered.

Described is a MOS gate-controlled SCR (UGSCR) structure with a U-shaped gate (UMOS) for an ESD protection circuit in an IC device which is compatible with shallow trench isolation (STI) and self-aligned suicide (salicide) fabrication technology. The UMOS gate is located in a p-substrate and is surrounded by an n-well on either side. Adjacent to one side of the UMOS gate, a first n+ diffusion is formed which straddles the first n-well. The n+ diffusion together with a p+ pickup diffused next to it form the cathode of the SCR (thyristor). Adjacent to the other side of the UMOS gate, a second n+ and p+ diffusion are formed in a second n-well. The second n+ and p+ diffusion together with the UMOS gate form the anode of the SCR and the input terminal of the circuit to be protected. The SCR is formed by the first n+ diffusion/n-well (cathode), the p-substrate, the second n-well and the second p+ /n+diffusion (anode). A latchup immune circuit is achieved by creating a U-shaped gate structure which is lined with a thick gate oxide--similar to a field oxide--under the poly gate.
