摘要： A device includes a first region, a second region disposed on the first region, a third region and a fourth region abutting the third region disposed in the second region, a fifth region disposed in the third region and coupled to a collector disposed above, and a sixth region disposed in the fourth region and coupled to an emitter disposed above. A first isolation is disposed between the collector and the emitter. A seventh region is disposed in the fifth region and coupled to the collector is spaced apart from the first isolation. The first region, the third region, the fifth region, the collector and the emitter have a first conductivity type different from a second conductivity type that the second region, the fourth region, the sixth region and the seventh region have.
