In a cell comprising an N well and a P well, a distance SP 04 from a center line of a contact N-type region to an N well end of the N well is set to be a distance which causes a transistor not to be affected by resist. A distance from a well boundary to the center line of the contact N-type region is equal to SP 04 . A design on the P well is similar to that on the N well. Thereby, modeling of the transistor in the cell can be performed, taking into consideration an influence from resist in one direction. Also, by fabricating a cell array which satisfies the above-described conditions, design accuracy can be improved.
