Abstract
A bipolar junction transistor is provided, including a semiconductor substrate and a doped layer of a first conductivity type, a doped well region of a second conductivity type formed in the doped layer, a first, second heavily doped region of the second conductivity type, and a third, fourth and fifth heavily doped region of the first conductivity type in the doped well region. The fifth heavily doped region is coupled with a first pin. The third and fourth heavily doped regions are coupled with a second pin. A sixth and seventh heavily doped region of the first conductivity type are disposed in the doped layer. The sixth and first heavily doped regions are connected in common. The seventh and second heavily doped regions are connected in common. When applying either a positive or negative surged mode, the bipolar junction transistor is formed, having both lateral and vertical conducting paths.
