Abstract
PURPOSE:To effectively protect the gate insulation of an MOS device against a breakdown in a protecting circuit connected to the MOS semiconductor device by specifying the mutual intervals of diffused layers connected to three input pads. CONSTITUTION:The input pads 30, 40, 50 for connecting the MOS device onto a semiconductor substrate are aligned thereon, a diffused layer 31 is connected to the pad 30, and is connected through an input protecting circuit 32 to a wire 34 reaching the internal circuit of the MOS device. Similarly, a diffused layer 41 is connected to the pad 40, is connected through an input protecting circuit 42 to a wire 44, the pad 50 is connected through a diffused layer 53 and an input protecting circuit 52 to a wire 54. In this configuration the diffused layers 31, 41 of the pads 30, 40 are confronted with small interval therebetween, the diffused layers 41, 51 of the pads 40, 50 are directed reversely with large interval therebetween. When high voltage is applied to the pads, a breakdown occurs at the portion having small interval and the MOS device can be thus safely secured.
