Abstract
A large chip includes a first set of branch wires that branch off from a first trunk wire and extend to respective wires so as to be connected to respective bond pads. Each of the branch wires of the first set includes a connection control element and a resistor. A small chip includes a second set of branch wires that branch off from a second trunk wire and extend to respective wires so as to be connected to respective bond pads. Each of the branch wires of the second set includes a connection control element and a resistor. Whether connection is properly made or not between the bond pads is determined by measuring a current value when voltage is applied to first and second test pads.
