发明名称 Semiconductor chip with contoured solder structure opening
摘要 Methods and apparatus to inhibit cracks and delaminations in a semiconductor chip solder bump are disclosed. In one aspect, a method of manufacturing is provided that includes forming a first dielectric layer over a first conductor structure of a semiconductor chip and forming a first opening in the first dielectric layer to expose at least a portion of the conductor structure. The first opening defines an interior wall that includes plural protrusions. A solder structure is coupled to the first conductor structure such that a portion of the solder structure is positioned in the first opening.
