Abstract:
A manufacturing method of a sensor chip having laminated first substrate and second substrate, an electrode layer sandwiched between the substrates and signal receiving portion provided on a surface of the first substrate remote from the electrode layer, the signal receiving portion being led from the electrode layer, the method comprising the steps of:forming a laminated wafer having base member of the second substrate and an array of a laminate of base member of the electrode layer and the first substrate disposed on the second substrate base member at a predetermined interval;applying a cover to the laminated wafer, the cover having a cut with a pattern corresponding to a configuration of the signal receiving portion, to expose a part of inside of the groove and a part of the surface of the first substrate base member along the groove from the cut;vaporizing and supplying a vapor deposition base member having conductivity to the cut to form a conductive layer extending continuously from a bottom of the groove exposed from the cut to the surface of the first substrate base member through a side thereof; andcutting an approximate center of the groove in width direction thereof with a smaller width than the width of the groove to divide into respective sensor chips.
