Abstract:
1. A semiconductor integrated circuit which is formed on one semiconductor substrate and which includes a first region and a second region, which is different from the first region, wherein, in the first region, a plurality of first cells having respectively given functions are arranged in a first direction, as well as in a second direction orthogonal to the first direction, wherein power source lines extend in the first direction and are arranged in the peripheral portions of the first cells, wherein the power source lines in the peripheral portions of the first cell are laid out at positions spaced away in the second direction from a boundary defined between the first cell and another first cell which is arranged close to the first cell in the second direction, wherein, in the second region, a plurality of second cells having respective given functions are arranged in the third direction as well as in a fourth direction orthogonal to the third direction, wherein power source lines extend in the third direction and are arranged in the peripheral portions of the second cells, wherein the power source line in the peripheral portion of one second cell is configured to be integrally formed with the power source line of another second cell, which is arranged close to the one second cell in the fourth direction, and wherein the power source lines are formed by embedding conductive film into grooves formed in an insulating film.
