A composite bond pad that is resistant to external forces that may be applied during probing or packaging operations is presented. The composite bond pad includes a non-self-passivating conductive bond pad (134) that is formed over a semiconductor substrate (100). A dielectric layer (136) is then formed over the conductive bond pad (134). Portions of the dielectric layer (136) are removed such that the dielectric layer (136) becomes perforated and a portion of the conductive bond pad (134) is exposed. Remaining portions of the dielectric layer (136) form support structures (138) that overlie that bond pad. A self-passivating conductive capping layer (204) is then formed overlying the bond pad structure, where the perforations in the dielectric layer (136) allow for electrical contact between the capping layer (204) and the exposed portions of the underlying bond pad (134). The support structures (138) provide a mechanical barrier that protects the interface between the capping layer (204) and the bond pad (134). Additional mechanical robustness is achieved when the support structures (138) remain coupled to the unremoved portion of the dielectric layer (136), as forces buffered by the support structures (138) are distributed across the dielectric layer (136) and not concentrated at the bond pad location.

A scanning microscope probe in which a palladium covering film is formed on the surface of the protruding portion of a cantilever, and the base end portion of a nanotube is disposed in contact with the palladium covering film with the tip end portion of the nanotube protruding to the outside, thus allowing the tip end to be used as a probe needle end for detecting signals.

A base unit for an insulated single and multi-strand aluminum wire crimping system includes a receptacle into which a quick-change crimp head may be slipped and locked. The crimp head includes a set of crimp-seal dies axially spaced from a set of continuity-crimping dies with both sets being mounted in a crimping die holder body. Both sets of dies perform crimping operations on the same contact-wire assembly. The crimp seal dies form the contact into a substantially smooth unbroken generally cylindrical wall hermetically sealed to the outside of the insulation on the core of the wire. The continuity-crimping dies crimp a wall of the contact into electrical contact with the core of the wire by indenting the wall into the wire. Ring cams drive the dies. These ring cams have internal cam profiles. The ring cams engage cam followers that are associated with the respective dies. The contact is received in the die holder body in a contact holder. The contact holder is quickly changeable. A sensor system prevents the crimping tool from unintentionally performing two crimping operations on the same contact-wire assembly, and detects non-compliant continuity-crimping.
