Patent ID: 7511518

Claim:
A method of making an interposer, said method comprising: providing a first dielectric layer including a plurality of openings therein; positioning a plurality of electrical conductors on said first dielectric layer; bonding a second dielectric layer including a plurality of openings therein to said first dielectric layer such that said plurality of said electrical conductors are positioned between said first and second dielectric layers; forming a first plurality of metallic contacts within said plurality of openings within said first dielectric layer, selected ones of said first plurality of metallic contacts including a protruding portion protruding from said first dielectric layer; and forming a second plurality of metallic contacts within said plurality of openings within said second dielectric layer, selected ones of said second plurality of metallic contacts including a protruding portion protruding from said second dielectric layer in an opposing direction from said selected ones of said first plurality of metallic contacts protruding from said first dielectric layer and being formed within said plurality of openings within said second dielectric layer so as to be positioned in an offsetting relationship with respect to a corresponding one of said selected ones of said first plurality of metallic contacts to form a plurality of paired contact locations with each of said pairs of said metallic contacts at said contact locations being electrically connected by a respective one of said electrical conductors such that said first and second dielectric layers, said first and second plurality of metallic contacts and said plurality of electrical conductors are adapted for tilting at each of said paired contact locations in response to the application of forces on said first and second metallic contacts at said paired contact locations to compensate for the application of said forces in an excessive manner.
