Abstract
An exemplary semiconductor integrated circuit is formed on a surface of a semiconductor chip includes a circuit region and a dummy region on the surface of the semiconductor chip. The circuit region includes a plurality of circuit patterns, which form circuit elements of the semiconductor integrated circuit, in a plurality of pattern layers. The dummy region includes a plurality of character dummies, which do not contribute to an operation of the semiconductor integrated circuit. The character dummies have a fixed shape and dimension, and arranged in a character pattern layer selected from the plurality of pattern layers with a fixed pitch. The dummy region further includes an identification sign formed by connecting selected ones of the character dummies chosen from the plurality of the character dummies.
