Patent ID: 7423441

Claim:
A multiple beam-synthesized type contactor assembly, each contactor comprising: a resin film constituting a base material; an electroconductive pattern formed over the resin film and made up of an electric conductor including a vertical probe; an electroconductive beam having a linear or curvilinear shape of which one end is fixed and the other is connected to the vertical probe; and one or a plurality of deformable beams extending substantially in parallel to the electroconductive beam, wherein the electroconductive beam and deformable beam(s) are firmly fixed mechanically in the vicinity of the vertical probe to constitute a cantilever of a parallel spring structure; the electroconductive beam and deformable beam(s) have an electrical characteristic of being electrically conductive or electrically non-conductive; and a plurality of the resin films each with a vertical probe are stacked, and circuit testing of semiconductor chips is carried out by collectively bringing the tips of the vertical probes into contact with the electrode pads of the semiconductor chips.
