摘要:
Embodiments of the present invention are directed to the formation of microprobe tips elements having a variety of configurations. In some embodiments tips are formed from the same building material as the probes themselves, while in other embodiments the tips may be formed from a different material and/or may include a coating material. In some embodiments, the tips are formed before the main portions of the probes and the tips are formed in proximity to or in contact with a temporary substrate. Probe tip patterning may occur in a variety of different ways, including, for example, via molding in patterned holes that have been isotropically or anisotropically etched silicon, via molding in voids formed in over exposed photoresist, via molding in voids in a sacrificial material that have formed as a result of the sacrificial material mushrooming over carefully sized and located regions of dielectric material, via isotropic etching of a the tip material around carefully sized placed etching shields, via hot pressing, and the like.
