IPC: H01L27/088
Filed: 1985-08-02
Abstract: PURPOSE:To prevent the latch-up caused by external surges effectively by separating the internal region from the external region by a P-type well region or an N-type well region and arranging only a single channel MOS transistor in the external region. CONSTITUTION:On an N-type semiconductor substrate 10, the internal region 4 where a logic circuit and others are constituted and the region 2 where a P-channel NOS transistor as a single channel MOS transistor is arranged and the external region including such as bonding pads 1 are provided. A P-type well region 3 for isolation which surrounds the internal region 4 is arranged. When a positive noise is applied, holes are implanted into the substrate 10. MOst of the implanted holes are absorbed in the region 3 before they reach the P-type well region. Accordingly, it is equivalent to that a current amplification factor of the P-N-P transistor becomes extremely small and the conditions for generating latch-up are not satisfied.
