摘要:
A method and apparatus for producing a substrate having a plurality of substantially co-planar bonding pads is provided. The substrate is employed in a probe apparatus used in wafer testing of wafer-mounted semiconductor integrated circuits. The bonding pads are formed by applying a plurality of bumps of electrically conductive material to a mounting surface of the substrate using a dispensing mechanism. The bumps are subsequently deformed into a plurality of substantially co-planar bonding pads using a flattening tool. The bonding pads provide a planar surface to which probes may be mounted, improving the accuracy and precision of positioning of tips of the probes.
摘要:
A probe card assembly is provided. The probe card assembly includes a substrate and a plurality of probes bonded to a surface of the substrate. The probe card assembly also includes a reinforcing layer provided on the surface of the substrate. The reinforcing layer is in contact with a lower portion of each of the probes, where a remaining portion of each of the probes is free from the reinforcing layer.

摘要:
A probe configured for use in the testing of integrated circuits includes a first end portion terminating in a foot (42), the foot defining a substantially flat surface configured to be connected to a substrate (400), a second end portion terminating in a tip (50), the tip being configured to contact an integrated circuit during testing of the integrated circuit, and a curved body portion (56) extending between the first end portion and the second end portion.
