Patent ID: 7514943

Claim:
A coordinate transforming apparatus for electrical signal connection comprising: a probe that has probe input terminals and probe output terminals arrayed in narrow-pitch lines which come into contact with and establish continuity to a wafer pad and in which the probe output terminals are arrayed two-dimensionally in a wide pitch over a substantial plane; a y-directional wiring group in which the probe output terminals and a plurality of transformation wiring input terminals cross each other to come into contact with and establish continuity among each other; and an x-directional wiring group that crosses and establishes continuity to the output terminals of the y-directional wiring group; wherein each individual wiring unit of the x-directional wiring group and the y-directional wiring group is formed over a resin film, and x-directional wiring group input terminals, x-directional wiring group output terminals, y-directional wiring group input terminals and y-directional wiring group output terminals protrude from the outer circumferences of the resin films.
