ABSTRACT:
An input-output circuit cell includes an input-output circuit formed on a semiconductor chip and having a signal terminal and an electric source terminal and a plurality of input-output bumps connected to the signal and electric-source terminals of the input-output circuit through wirings respectively, the plurality of input-output bumps being made to correspond to the input-output circuit and arranged at a center in a plane of projection of the input-output circuit. Accordingly, the input-output circuit is disposed in an arbitrary position on the semiconductor chip.
