ABSTRACT:
A semiconductor integrated circuit, in which an isolation region with one conductivity type and a plurality of island regions with another conductivity type separated by the isolation region are provided, is disclosed. In this case, a high resistance polycrystalline semiconductor layer is formed to cover whole of a surface portion of a PN-junction formed between the isolation region and the island regions.
