Abstract: The article comprises a sintered ceramic, and an adherent coating of a dielectric material on at least a part of the surface of said ceramic, said coating forming a compressive layer on said part of said ceramic surface. The method for forming e.g. such articles comprises, depositing onto at least a portion of said ceramic article an adherent layer of dielectric material, said layer forming a compressive layer on cooling.

Abstract: The present invention is directed to a structure comprising a substrate having a surface; a plurality of elongated electrical conductors extending away from the surface; each of said elongated electrical conductors having a first end affixed to the surface and a second end projecting away from the surface; there being a plurality of second ends; and a means for maintaining the plurality of the second ends in substantially fixed positions with respect to each other. The structure is useful as a probe for testing and burning in integrated circuit chips at the wafer level.

Abstract: A solder composition and associated method of formation. The solder composition comprises a substantially lead-free alloy that includes tin (Sn), silver (Ag), and copper. The tin has a weight percent concentration in the alloy of at least about 90%. The silver has a weight percent concentration X in the alloy. X is sufficiently small that formation of Ag3Sn plates is substantially suppressed when the alloy in a liquefied state is being solidified by being cooled to a lower temperature at which the solid Sn phase is nucleated. This lower temperature corresponds to an undercooling deltaT relative to the eutectic melting temperature of the alloy. Alternatively, X may be about 4.0% or less, wherein the liquefied alloy is cooled at a cooling rate that is high enough to substantially suppress Ag3Sn plate formation in the alloy. The copper has a weight percent concentration in the alloy not exceeding about 1.5%.

Abstract: Sealing and stress relief are provided to a low-fracture strength glass-ceramic substrate. Hermeticity is addressed through the use of capture pads in alignment with vias and through polymeric overlayers with interconnection between the underlying via or pad metallurgy and the device, chip, wire or pin bonded to the surface of the layer. Multilevel structures are taught along with a self-aligned sealing and wiring process.

The tin has a weight percent concentration in the alloy of at least about 90 %. The silver has a weight percent concentration X in the alloy. X is sufficiently small that formation of Ag3Sn plates (57, 58) is substantially suppressed when the alloy in a liquefied state is being solidified by being cooled to a lower temperature at which the solid Sn phase is nucleated. This lower temperature corresponds to an undercooling .delta.T relative to the eutectic melting temperature of the alloy.

Abstract: The present invention relates to an improved pinless connector for use in microelectronics having an elastomer resin comprising polysiloxane and filler. In particular the elastomer resin has a tensile strength greater than 170 psi and comprises (i) a crosslinked polysiloxane comprising about 70 to 90 weight % of a crosslinked random copolymer of dimethylsiloxane and diphenylsiloxane and (ii) about 10 to 30 weight % of filler comprising zinc oxide and a lanthanide oxide.
