Abstract:
A packaging and interconnection of a contact structure, comprising:a contact structure made of conductive material and formed on a contact substrate through a photolithography process, said contact structure having a base portion vertically formed on said contact substrate, a horizontal portion, one end of which being formed on said base portion, and a contact portion vertically formed on another end of said horizontal portion;a contact trace formed on said contact substrate and electrically connected to said contact structure at one end, the other end of said contact trace being formed of a contact pad;a connection target provided at an outer periphery of said contact trace to be electrically connected with said contact pad;a bonding wire for electrically connecting an upper surface of the contact pad and the contact target;an elastomer provided under said contact substrate for allowing flexibility in said interconnection and packaging; anda support structure provided under said elastomer for supporting said contact structure, said contact substrate and said elastomer;wherein substantially all portions of said contact structure are projected from said contact substrate to a free space to allow free movements of at least said horizontal portion and said contact portion, and wherein said horizontal portion of said contact structure produces a contact force when said contact structure is pressed against a contact target, thereby achieving a scrubbing effect on a surface of the contact target.
