Abstract

PURPOSE:To prevent electrostatic breakdown and latch-up by forming a diffusion resistor and surrounding the periphery of a well by a guard band. CONSTITUTION:The circuit is formed which passes the n<+> diffusion resistor through a poly Si resistor 8 from a bonding pad B.P and one part itself thereof is grounded through a diode D1 and the other part thereof through a protective diode D2. Accordingly, the protective diode which is easy to be broken most by the electrostatic breakdown is protected. Current concentration can be prevented by the breakdown of a junction diode which can be parasitized to diffusion resistor itself. The latch-up to a MOSIC at the time when minus charges are injected into a substrate by the diffusion resistor 4 due to noises, etc. is obviated by means of the guard band 7.
