ABSTRACT:
In accordance with the invention, a high density z-direction interconnection medium is made by the steps of providing a non-conductive membrane having z-direction channels, filling the channels with liquid precursor of conductive material, converting the trapped precursor into conductive material within the channels, and, advantageously, forming solder bumps in contact with the conductive material in the channels. The method is particularly useful for forming hollow tubular or porous conductive pathways having enhanced resistance to thermal and mechanical stress. The channels can be conveniently filled by vacuum suction,
