Abstract:
A semiconductor integrated circuit includes a first conduction-type semiconductor region, a second conduction-type first impurity region, and a guard ring formed using a first conduction-type second impurity region so as to form a protection device of an electrostatic protection circuit. The first impurity region is formed inside the semiconductor region to have a rectangular planar structure with long and short sides. The guard ring is formed inside the semiconductor region to surround the periphery of the first impurity region. A weak spot is formed on the short side of the rectangular planar structure of the first impurity region. A plurality of electrical contacts are formed in a first portion of the guard ring which faces the long side of the rectangle. A plurality of electrical contracts are not formed in a second portion of the guard ring which faces the weak spot formed on the short side of the rectangle.

Claim (Index 34):
The semiconductor integrated circuit according to  claim 33 ,\n wherein the one of the plurality of first impurity regions which functions as the source of the MOS transistor is one of a plurality of source impurity regions, the other of the plurality of first impurity regions which functions as the drain of the MOS transistor is one of a plurality of drain impurity regions, and the gate electrode of the MOS transistor is one of a plurality of gate electrodes, and the plurality of source impurity regions, the plurality of gate electrodes, and the plurality of drain impurity regions are formed inside the guard ring.
