Patent ID: 8080883

Claim:
A semiconductor integrated circuit device including a plurality of wirings of different lengths placed in parallel on a plane, said semiconductor integrated circuit device comprising: a 1 st longest wiring being arranged to extend in a first direction among the plurality of wirings; a 1 st shortest wiring among the plurality of wirings adjacently being placed to the 1 st longest wiring, said 1 st shortest wiring being arranged in parallel with said 1 st longest wiring along said first direction; a (n+1)th shortest wiring, longer than said 1 st shortest wiring, adjacently being placed to a (n)th longest wiring, at an outside of a place which is surrounded by a (n)th shortest wiring, shorter than said (n+1)th shortest wiring, and the (n)th longest wiring, said (n+1)th shortest wiring being arranged in parallel with said 1st longest wiring along said first direction, said (n+1)th shortest wiring being longer than said (n)th shortest wiring; and a (n+1)th longest wiring, shorter than said (n)th longest wiring, adjacently being placed to the (n)th shortest wiring at an outside of a place which is surrounded by the (n)th shortest wiring and the (n)th longest wiring, said (n+1)th longest wiring being arranged in parallel with said 1st shortest wiring along said first direction, wherein n is an integer greater than or equal to 1.
