Abstract:
1. A method for fabricating a plurality of elastic probes in a row, wherein each of the elastic probes has a first end portion, a plurality of elastic bending portions, a middle portion, and a second end portion, the method comprising the steps of: providing a substrate having a flat surface; creating a recess in the flat surface of the substrate, the recess having a bottom and a plurality of inner sides; forming a photoresist layer on the flat surface of the substrate and in the recess; patterning the photoresist layer to form a plurality of slots crossing the recess, wherein the slots are connected; forming a probe metal layer in the slots of the photoresist layer, wherein at least a part of the probe metal layer lying on the flat surface of the substrate includes the first end portions and the second end portions of the elastic probes, at least a part of the probe metal layer lying on the bottom of the recess includes the middle portions of the elastic probes, at least a part of the probe metal layer lying on the inner sides of the recess includes the elastic bending portions of the elastic probes, wherein the probe metal layer further comprising a connecting bar integrally connecting to the second end portions of the elastic probes; removing the photoresist layer and the substrate; mounting the first end portions of the elastic probes in a plurality of connecting holes of a probe head; and removing the connecting bar after mounting the elastic probes.
