US 2008/0157124 A1 · SEMICONDUCTOR INTEGRATED CIRCUIT

Abstract

In a semiconductor integrated circuit device, a plurality of electrode pads for external connection are arranged in a zigzag pattern. Some electrode pads of the electrode pads of the plurality of I/O cells which are closer to a side of the semiconductor chip, each have an end portion closer to the side of the semiconductor chip, the end portion being set at the same position as that of an end portion of the corresponding I/O cell. A power source-side protective circuit and a ground-side protective circuit against discharge of static electricity are provided with the power source-side protective circuit being closer to the scribe region. A distance between a center position of one of the electrode pads and the ground-side protective circuit of the corresponding I/O cell and a distance between a center position of the other one electrode pad and the ground-side protective circuit of the corresponding I/O cell are both short and are substantially equal between each I/O cell.
