摘要: 在常规UBM例如Cu、Ni或NiP中,存在的这样问题:在长时间将电子部件保持在高温条件下时导致UBM的阻挡特性被破坏,并且由于在结合界面形成脆性的合金层,导致结合强度降低。焊料连接部分在高温下储存之后长期连接可靠性降低的问题得到了解决。电子部件上提供有:安置在基板或半导体元件上的电极片;和为覆盖所述电极片而安置的阻挡金属层。所述阻挡金属层在与所述电极片接触侧相反的一侧上包含CuNi合金层,所述CuNi合金层含有15至60原子%的Cu和40至85原子%的Ni。

摘要: 本发明提供了一系列新工艺用以通过电镀方法,制备可用于半导体封装,具有微细间距、良好可靠性的焊球。本发明所采用的新工艺技术可适用于不同组分的电镀铅-锡合金焊料、无铅的锡基焊料(如:铜-锡、锡-铜-银、锡-银、锡-铋合金)等。其工艺能够满足焊球边间距50微米以上,焊球直径在50至300微米的需求。在本发明中,通过采用凸点回流控制层,避免了工艺过程中焊料的损失,从而能够制备微细间距和高可靠性焊球。通过对关键工艺和电镀金属层的控制,以调整电镀层微观结构,本发明能够制备用于倒装焊封装的高可靠性焊球。本发明同时应用特殊设计涂覆光胶构件和光刻工艺,以满足微细间距电镀凸点的工艺制备要求。
