Abstract:
Methods and apparatus for solder connections. An apparatus includes a substrate having a conductive terminal on a surface; a passivation layer overlying the surface of the substrate and the conductive terminal; an opening in the passivation layer exposing a portion of the conductive terminal; at least one stud bump bonded to the conductive terminal in the opening and extending in a direction normal to the surface of the substrate; and a solder connection formed on the conductive terminal in the opening and enclosing the at least one stud bump. Methods for forming the solder connections are disclosed.
