Flip-chip package having thermal expansion posts
Abstract:
A semiconductor package having a substrate and a die includes a plurality of conductive posts attached to the substrate and bonded to an active surface of the die via a plurality of corresponding microbumps. The conductive posts are flexible and extend beyond the top surface of the substrate a sufficient distance to absorb lateral forces exerted upon the microbumps.
