Patent ID: 7898008

Claim:
A vertical-type integrated bipolar device, comprising: an active layer, of semiconductor material, having a surface; a first delimitation trench, surrounding a first active area in said active layer; a second delimitation trench, surrounding a second active area in said active layer; a first buried layer of a first conductivity type inside said first active area; a second buried layer of a second conductivity type inside said second active area; a first well region of the first conductivity type inside said first active area and on top of the first buried layer; a second well region of the second conductivity type inside said second active area and on top of the second buried layer; a first top sinker region of the first conductivity type, extending inside said first active area and on top of said first well region, said first top sinker region facing said surface and being electrically coupled to said first buried layer; a second top sinker region of the second conductivity type, extending inside said second active area and on top of said second well region, said second top sinker region facing said surface and being electrically coupled to said second buried layer; a first buried collector region, of the first conductivity type, extending inside said first active area, on top of said first well region and laterally with respect to said first top sinker region; a second buried collector region, of the second conductivity type, extending inside said second active area, on top of said second well region and laterally with respect to said second top sinker region; a first base region, of the second conductivity type, extending inside said first active area, on top of said first buried collector region and laterally with respect to said first top sinker region, said first base region facing said surface; a second base region, of the first conductivity type, extending inside said second active area, on top of said second buried collector region and laterally with respect to said second top sinker region, said second base region facing said surface; a first emitter region, of the first conductivity type, extending inside said first base region and facing said surface; a second emitter region, of the second conductivity type, extending inside said second base region and facing said surface; a first termination region being between said surface and said first well region, being arranged between said first top sinker region and the first base region, and extending below at least a portion of the first base region; and a second termination region being between said surface and said second well region, being arranged between said second top sinker region and the second base region, and extending below at least a portion of the second base region.
