Abstract
Abstract In a master slice integrated circuit device composed of an array of internal cells having contact members, an array of external cells having contact members and formed outwardly from the internal cell array, a main power circuit region formed on the external cell array, a plurality of power lines formed on the internal array region, and a plurality of signal lines for electrically interconnecting selected contact members of the internal and external cells, intermediate power line connection regions are provided to conductively connect each power line to the main power circuit region, the intermediate connection regions including, for each power line, a power branch-off member disposed at a given position on the main power circuit region and extending substantially in the direction of its respective power line, and a connection allowance member intersecting, and connected to, the power branch-off member and having a predetermined length, the connection allowance member being conductively connected between its associated power branch-off member and the respective power line.
