Title: Pnpn surge-preventing device
Inventor: KAMIJO YOSHIAKI
IPC: H01L29/747
Filed: 1988-06-06
Abstract: PURPOSE:To improve resistance to lightening surge overcurrent as required, by forming base regions such that a depth directly under emitter regions is smaller than that directly under ohmic regions. CONSTITUTION:A surge-preventing device is constructed such that diffusion depths XjB3, XjB3' of base regions 2, 2' directly under ohmic regions 5, 5' are larger than diffused depths XjB4, XjB4' of base regions 2, 2' directly under emitter regions 3, 3' and hence the depth XjB4 becomes smaller than the depth XjB3 after completion of diffusion of the emitter regions 3, 3'. According to such construction, junction J211, J211' directly under the emitter regions 3, 3' have a breakdown voltage lower than that of junctions J212, J212' directly under the ohmic regions 5, 5'. Accordingly, when a positive voltage is applied to the electrode 7, current is conducted to the joints J211, J211' from the beginning. As a result, the transition point current IS and the turn-on time ton are decreased. Consequently, the surge-preventing device produced in this manner is allowed to have low transition point current IS, large holding current IH and high resistance to lightening surge current.
