<p>PROBLEM TO BE SOLVED: To solve the problem of a micro-integrated circuit that the gate orientation of a core transistor constituting a core logic circuit, etc., cannot be changed for various reasons, and, in an I/O cell, etc, too, the cell cannot be rotated, making it impossible to utilize a layout suitable for an I/O cell placement region along each side of a semiconductor chip region easily by rotating one standard I/O cell as necessary.SOLUTION: The present invention is such that one I/O cell along one side of a chip and some other I/O cell along a side adjacent thereto in a semiconductor integrated circuit device having a MISFET have following relationship. That is, a sub-cell of the other I/O cell has such a relation that a square element cell in one sub-cell of the one I/O cell is vertically or horizontally inverted individually, and other sub-cells of the other I/O cell have such a relation that other sub-cells of the one I/O cell are rotated by an angle equivalent to 90 degrees.</p> |
