Abstract:
1. An interposer comprising: a first dielectric layer including a plurality of openings therein; a first plurality of metallic contacts located 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; a second dielectric layer bonded to said first dielectric layer and including a plurality of openings therein; a second plurality of metallic contacts located 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, each of said selected ones of said first plurality of metallic contacts being positioned in an offsetting relationship with respect to a corresponding one of said selected ones of said second plurality of metallic contacts to form a paired contact location; and a plurality of electrical conductors positioned substantially between said first and second dielectric layers, each of said electrical conductors electrically connecting selected ones of said first plurality of metallic contacts with respective ones of said selected ones of said second plurality of metallic contacts, said interposer, including said first and second dielectric layers, said first and second plurality of metallic contacts and said plurality of electrical conductors, being adapted for tilting at each of said paired contact locations of said first and second metallic contacts in response to the application of forces on said first and second metallic contacts at said paired locations to compensate for the application of said forces in an excessive manner.
