Abstract

PURPOSE:To shorten evaluation manhours by inputting and outputting signal through monitor pads independently for each block to evaluate by each single block in evaluation of a semiconductor integrated circuit device. CONSTITUTION:A monitor pad cell 1 is inserted between monitoring signal lines, e.g. a signal line 1 (9) that is the output of a block 1 (7) and a signal line 2 (10) that is the input of a block 2 (8). Therefore, cutting a fuse element 6 with laser beams or the like allows output signal of the block 1 (7) to be outputted from the first monitor pad 2, and the input signal of the block 2 (8) to be inputted from the second monitor pad 3. Further cutting the fuse element 6 with laser beams or the like allows signal to be inputted to and outputted from a single block through monitor pads.
