Patent ID: 7602041

Claim:
An intermediate product for a semiconductor integrated circuit having an input protection circuit, before being mounted on a circuit board, the input protection circuit comprising: a semiconductor chip; an internal circuit disposed on the semiconductor chip: a plurality of terminal groups which are disposed on the semiconductor chip, having a plurality of input/output terminals linearly arranged on the semiconductor chip, the plurality of input/output terminals being connected respectively to the internal circuit; a plurality of fusing parts disposed on the semiconductor chip and respectively disposed alternately between input/output terminals adjacent to each other among the plurality of input/output terminals so as to connect serially the plurality of input/output terminals in each of the plurality of terminal groups, each of the plurality of terminal groups forming a current path by an arrangement of the plurality of input/output terminals and the plurality of fusing parts; and an electrical wiring disposed on the semiconductor chip, connecting the plurality of terminal groups to each other so that a current can flow from one current path to another current path through the electrical wiring; wherein the plurality of fusing parts are respectively configured to be blown out so that the plurality of input/output terminals are electrically separated respectively from each other after the intermediate product is mounted on the circuit board.
