摘要：
A conductor line is placed at a layer overlying an input protection circuit electrically coupled to a pad such that the conductor line covers at least a part of the input protection circuit. The conductor line having a sufficiently large width disperses and absorbs the heat generated from the input protection circuit. Since the input protection circuit and the conductor line have a region overlapping with each other in the layout of plan view, an area for layout of the input protection circuit on a chip can be reduced effectively, and prevention of a destruction of the protection circuit due to the heat as well as an improvement of a resistance to the surge can be obtained.
