<P>PROBLEM TO BE SOLVED: To prevent a shortage of a connection pad for a power supply to a core region, to eliminate a necessity for decreasing a cell width of an IO cell, and to be able to apply an identical connection method to the all connection pads. <P>SOLUTION: A line of connection pads 41a to 41c and a line of connection pads 42a to 42d are arranged on IO cells 31a to 31g in an IO region 30 in a shifted manner, connection pads 43a to 43d are arranged on a core power wiring 21 among a side of a core region 20, and three connection pads per two IO cells are arranged with the relation between the respective pad pitch P of the connection pads 41a to 41c, 42a to 42d, 43a to 43d; the cell pitch S in the IO cells defined as P=2S; and the pad pitch of all connection pads 41a to 41c, 42a to 42d, 43a to 43d defined as P/3 (=2S/3). <P>COPYRIGHT: (C)2008,JPO&INPIT |
