Abstract:
A method of fabricating a connector for a microelectronic device having bump leads comprising steps of:providing a conductive sheet having a front and a back surface and a plurality of conductive posts extending downwardly from the back surface towards a substrate spaced apart from the back surface, each post having a bottom end secured to the substrate and a top end, the posts being disposed in an array of post groups, each post group including a plurality of posts defining a gap therebetween, and thenselectively etching the conductive sheet to form contacts extending laterally from the top ends of the posts of each group toward the gap defined by each group, said selective etching forming an opening in said conductive sheet between said contacts in alignment with said gap between said posts of each post group, said opening operative for at least partially receiving a portion of said bum; lead therein while said bump lead engages said contacts of said posts of each said post group.
