Abstract:
An integrated circuit includes a bipolar transistor comprising a substrate and a collector formed in the substrate. The collector includes a highly doped lateral zone, a very lightly doped central zone and a lightly doped intermediate zone located between the central zone and the lateral zone 4a of the collector. The substrate includes a lightly doped lateral zone and a highly doped central zone. The dopant species in the zone of the substrate are electrically inactive.
