摘要： A semiconductor package includes a substrate, through-electrodes penetrating the substrate, first bumps spaced apart from each other in a first direction parallel to a top surface of the substrate and electrically connected to the through-electrodes, respectively, and at least one second bump disposed between the first bumps and electrically insulated from the through-electrodes. The first bumps and the at least one second bump constitute one row in the first direction. A level of a bottom surface of the at least one second bump from the top surface of the substrate is a substantially same as levels of bottom surfaces of the first bumps from the top surface of the substrate.

摘要： A bump structure for electrically coupling semiconductor components is provided. The bump structure includes a first bump on a first semiconductor component and a second bump on a second semiconductor component. The first bump has a first non-flat portion (e.g., a convex projection) and the second bump has a second non-flat portion (e.g., a concave recess). The bump structure also includes a solder joint formed between the first and second non-flat portions to electrically couple the semiconductor components.

摘要： A bump structure includes a contact element formed on a substrate and a passivation layer overlying the substrate. The passivation layer includes a passivation opening exposing the contact element. The bump structure also includes a polyimide layer overlying the passivation layer and an under bump metallurgy (UBM) feature electrically coupled to the contact element. The polyimide layer has a polyimide opening exposing the contact element, and the under bump metallurgy feature has a UBM width. The bump structure further includes a copper pillar on the under bump metallurgy feature. A distal end of the copper pillar has a pillar width, and the UBM width is greater than the pillar width.
