Abstract:
A method of forming an array of contact structures for providing electrical connection to an integrated circuit, said method comprising:providing a body of rigid dielectric substrate; forming from said body of rigid dielectric substrate a plurality of raised members, each of said plurality of raised members having a top surface distal to said body of rigid dielectric substrate; forming a plurality of conductive layers, each of said plurality of conductive layers being formed over at least a portion of the top surface of each of said plurality of raised members, said plurality of raised members being sized and spaced such that said plurality of conductive layers are capable of being removably and electrically engaged with an array of electrical leads of said integrated circuit; and forming one or more projecting apex structures in said portion of the top surface of each of said plurality of raised members, wherein one or more of said plurality of conductive layers are formed on said one or more projecting apex structures.
