摘要： The mechanism of forming a metal bump structure described above resolves the delamination issues between a conductive layer on a substrate and a metal bump connected to the conductive layer. The conductive layer can be a metal pad, a post passivation interconnect (PPI) layer, or a top metal layer. By performing an in-situ deposition of a protective conductive layer over the conductive layer (or base conductive layer), the under bump metallurgy (UBM) layer of the metal bump adheres better to the conductive layer and reduces the occurrence of interfacial delamination. In some embodiments, a copper diffusion barrier sub-layer in the UBM layer can be removed. In some other embodiments, the UBM layer is not needed if the metal bump is deposited by a non-plating process and the metal bump is not made of copper.

摘要翻译： 上述形成金属凸块结构的机构解决了基板上的导电层与连接到导电层的金属凸块之间的分层问题。 导电层可以是金属焊盘，后钝化互连（PPI）层或顶层金属层。 通过在导电层（或基底导电层）上进行保护性导电层的原位沉积，金属凸块的凸块下金属（UBM）层更好地粘附到导电层并减少界面分层的发生。 在一些实施例中，可以去除UBM层中的铜扩散阻挡子层。 在一些其它实施例中，如果通过非电镀工艺沉积金属凸块并且金属凸块不是由铜制成的，则不需要UBM层。

摘要： An embodiment of the disclosure includes a conductive feature on a semiconductor die. A substrate is provided. A bond pad is formed over the substrate. The bond pad has a first width. A polyimide layer is formed over the substrate and the bond pad. The polyimide layer has a first opening over the bond pad with a second width. A silicon-based protection layer overlies the polyimide layer. The silicon-based protection layer has a second opening over the bond pad with a third width. The first opening and the second opening form a combined opening having sidewalls to expose a portion of the bond pad. A UBM layer is formed over the sidewalls of combined opening to contact the exposed portion of the bond pad. A conductive feature overlies the UBM layer.

摘要： A sidewall protection structure is provided for covering at least a portion of a sidewall surface of a bump structure, in which a protection structure on the sidewalls of a Cu pillar and a surface region of an under-bump-metallurgy (UBM) layer is formed of at least one non-metal material layers, for example a dielectric material layer, a polymer material layer, or combinations thereof.
