An integrated circuit die test probe has a non-flat tip. In one embodiment, the tip has an elongated pyramid shape that provides a cutting action while probing solder covered conductive pads. The tip shape helps maintain a uniform tip to pad resistance during testing by penetrating the solder layer and avoiding solder residue build up. The test probes significantly reduce the need for cleaning the probe tips to remove residue.

Integrated circuit test probe having ridge contact

A method of exposing a bond pad includes: providing an integrated circuit having a bond pad, a first passivation layer overlying an area portion of the bond pad, and a second passivation layer overlying the first passivation layer; removing a portion of the second passivation layer above the area portion of the bond pad exposing an area of the first passivation layer; curing the second passivation; and etching a portion of the exposed area of the first passivation layer to expose the top surface of the bond pad. A method of coupling an integrated circuit chip to a chip package is also disclosed as is a method of probing the bond pads of an integrated circuit. A probe card is further disclosed, including a probe assembly coupled to a printed circuit board, the probe assembly having a sloped sidewall portion with a plurality of probing beams extending from the sidewall portion.

Integrated passivation process, probe geometry and probing process

A method of testing an integrated circuit device including depositing a solder bump on a surface of a bond pad on an integrated circuit device, heat treating the solder bump, and testing the integrated circuit device by probing the solder bump.
