    • An electronic device has a die that is attached to a metallic contact of a substrate via a coupling layer. The coupling layer comprises an alloy of at least two metals selected from the group consisting of Zn, Al, Mg, and Ga, and further comprises at least one sacrificial chemical element other than Zn, Al, Mg, and Ga at a concentration of 10-1000ppm with an oxygen affinity higher than the alloy. Alternative alloys comprise at least two metals selected from the group consisting of Sn, Ag, Bi, Zn, and Cu, and at least one sacrificial chemical element other than Sn, Ag, Bi, Zn, and Cu. Still further contemplated alloys comprise at least two metals selected from the group consisting of Sn, Ag, Bi, and Sb, and at least one sacrificial chemical element other than Sn, Ag, Bi, and Sb. These Pb free alloys demonstrate improved wetting characteristics and can be used for high reliability soldering process for microelectronics applications.
    • 电子器件具有通过耦合层附接到衬底的金属接触件的管芯。 耦合层包括选自Zn,Al,Mg和Ga中的至少两种金属的合金,并且还包含浓度为10的除Zn,Al,Mg和Ga以外的至少一种牺牲化学元素 -1000ppm,氧合金比合金高。 替代合金包含选自Sn,Ag,Bi,Zn和Cu中的至少两种金属,以及除Sn,Ag,Bi,Zn和Cu以外的至少一种牺牲化学元素。 进一步考虑的合金包括选自Sn,Ag,Bi和Sb中的至少两种金属,以及除Sn,Ag,Bi和Sb以外的至少一种牺牲化学元素。 这些无铅合金表现出改善的润湿特性,可用于微电子应用的高可靠性焊接工艺。
