发明名称 METHOD OF FABRICATING BUMP STRUCTURE AND BUMP STRUCTURE
摘要 A method of forming a semiconductor device includes forming an under-bump metallurgy (UBM) layer overlying a portion of a metal pad region within an opening of an encapsulating layer over a semiconductor substrate, and forming a bump layer overlying the UBM layer to fill the opening of the encapsulating layer. A removal process is initiated on an upper surface of the encapsulating layer and a coplanar top surface of the bump layer to remove the upper surface of the encapsulating layer until a top portion of the bump layer protrudes from the encapsulating layer.
