Classification: CPC H | IPC H

Claim 18:
19. A microelectronic assembly, comprising:
a first substrate comprising a first bonding surface, the first substrate comprising
a first through substrate via (TSV),
a first metal contact pad at the first bonding surface, the first metal contact pad aligned with and in electrical contact with the first TSV, and
a second metal contact pad at the first bonding surface, the second metal contact pad without a corresponding TSV in the first substrate, wherein the first metal contact pad has a larger surface area than the second metal contact pad; and

a second substrate comprising a second bonding surface, the second substrate comprising
a third metal contact pad at the second bonding surface, and
a fourth metal contact pad at the second bonding surface;

wherein the first bonding surface is direct hybrid bonded to the second bonding surface such that the first metal contact pad is directly bonded to the third metal contact pad and the second metal contact pad is directly bonded to the fourth metal contact pad.
