Abstract
According to the invention, in input/output circuit portions positioned around a semiconductor chip, electrode pads are arranged above each of a plurality of input/output cells arranged in a line. The width of the electrode pads is greater than the width of the input/output cells, and thus the electrode pads cannot be arranged in a single line and are instead arranged staggered in two lines. The electrode pads of one row are arranged shifted so that they do not overlap with the internal terminals of the input/output cells, but are disposed near these internal terminals. The spacing between the electrode pads is set to a distance that is at least a set distance determined by the isolation rules of the design.
Claims12
A semiconductor device comprising:
- a plurality of cells having output transistors formed on a substrate;
- and
- a plurality of electrode pads connected to output transistors of corresponding cells for outputting an output of said output transistors to the outside,
- wherein the electrode pads are positioned above corresponding cells in the thickness direction of the substrate and arranged in a staggered fashion, distanced from the electrode pads of adjacent cells by at least a set distance.
