Patent ID: 8759883

Claim:
A semiconductor integrated circuit device, comprising: a semiconductor chip, including a semiconductor substrate, on which an internal circuit is disposed; a plurality of I/O cells disposed on the semiconductor chip and provided in parallel with a periphery of the semiconductor chip, each of the plurality of I/O cells having only a data input function, only a data output function, or both data input and output functions, and including a protective circuit for protecting the internal circuit from discharge of static electricity; and a plurality of electrode pads, each corresponding to one of the plurality of I/O cells and connected to the corresponding one of the plurality of I/O cells, the plurality of electrode pads being arranged in a zigzag pattern, wherein: at least one of the plurality of electrode pads has an overlapping portion overlapping the corresponding I/O cell and a remaining portion not overlapping any one of the plurality of I/O cells and positioned farther inside the semiconductor chip than the corresponding I/O cell, and a circuit element different from the I/O cell is provided below the remaining portion.
