Patent ID: 8564127

Claim:
A semiconductor device comprising a semiconductor chip in the form of a rectangle having a pair of short sides and a pair of long sides: wherein the semiconductor chip includes: (a) a plurality of first bump electrodes arranged along a first long side of the semiconductor chip and arranged at a position closer to the first long side than to a second long side in opposition to the first long side; (b) an internal circuit formed in the semiconductor chip; and (c) a plurality of first electrostatic protection circuits which protect the internal circuit against static electricity and are electrically coupled to the first bump electrodes; wherein a first part of the first electrostatic protection circuits are arranged at a position that overlaps the first bump electrodes to which said first part of the first electrostatic protection circuits are electrically coupled, in a planar view; a remaining part of the first electrostatic protection circuits are arranged at a position different from a position that overlaps the first bump electrodes to which said remaining part of the first electrostatic protection circuits are electrically coupled, in a planar view; the remaining part of the first electrostatic protection circuits are all entirely inward of the first part of the first electrostatic protection circuits, in a direction towards the second long side.
