  • Patent number: 8405416
    Abstract: A probe includes a wire and a bump, wherein the wire is formed on a substrate; and the bump is formed upon the wire. In addition, a probe block includes a plurality of probes disposed on a substrate, so that the probe block is composed of a plurality of wires and bumps. The wires are disposed on the substrate and each bump is disposed accurately upon an end of each wire. The bump and the wire of the probe in accordance with the present invention are formed jointlessly. A method of fabricating the probe is characterized in that a grayscale mask is utilized to form the wire on the substrate and form the bump upon the wire by using a single masking process.
