ABSTRACT:
A needle alignment verification circuit includes a sensor pad, a first transmission line, a control element, a data pad, a second transmission line, and a response element. The sensor pad includes an insulation part and a conduction part. The first transmission line is electrically connected to the conduction part and to the interior of the semiconductor device. The control element asserts the first transmission line at a first logic state, and upon receiving the probe signal at the conduction part, transitions the logic state of the first transmission line to a second logic state. The second transmission line provides a predetermined signal to the data pad. The response element controls the second transmission line so that the second transmission line has the state of a verification result voltage for a misalignment state in response to the second logic state.
