<p>PURPOSE:To increase the number of I/O terminals with which a chip area can effectively by made usable by specifying one angle of at least one cell among cells to a specific angle or lower. CONSTITUTION:I/O terminals 101, 102, 103, 104 are disposed along a chip side 100, inside of which I/O terminals there are disposed an I/O circuit cell 107 corresponding to the I/O terminal 103, and an I/O circuit cell 108 corresponding to the I/O terminal 104. The I/O cell is configured to be a parallelogram with one angle of 45 degree.</p> |
