    摘要: The various embodiments of the present invention provide a stress-relieving, second-level interconnect structure that is low-cost and accommodates TCE mismatch between low-TCE packages and PCBs. The various embodiments of the interconnect structure are reworkable and can be scaled to pitches from about 1 millimeter (mm) to about 150 micrometers (μm). The interconnect structure comprises at least a first pad, a supporting pillar, and a solder bump, wherein the first pad and supporting pillar are operative to absorb substantially all plastic strain, therefore enhancing compliance between the two electronic components. The versatility, scalability, and stress-relieving properties of the interconnect structure of the present invention make it a desirable structure to utilize in current two-dimensional and ever-evolving three-dimensional IC structures.

    摘要: The lifetime of multiple capillary nozzle assemblies embedded in a glass mass, of a multiple nozzle ink-jet printer, can be increased and the thermal and mechanical compatibility of the resulting package enhanced by fabrication of the nozzles from glass compositions comprised of SiO.sub.2, ZrO.sub.2, Na.sub.2 O, K.sub.2 O and MgO. Inclusion of ZrO.sub.2 as well as minor amounts of BaO, MgO, CaO, and Al.sub.2 O.sub.3 enhances the alkali resistance of the glass nozzles. Also, the high SiO.sub.2 content of the glasses combined with the presence of ZrO.sub.2, MgO, CaO, and Al.sub.2 O.sub.3 imparts an acid resistance to the nozzles.
