Abstract
A bonded assembly includes a first semiconductor die and a second semiconductor die. The first semiconductor die includes first metallic bonding pads embedded in first dielectric material layers, the second semiconductor die includes second metallic bonding pads embedded in second dielectric material layers, the first metallic bonding pads are bonded to a respective one of the second metallic bonding pads; and each of the first metallic bonding pads includes a corrosion barrier layer containing an alloy of a primary bonding metal and at least one corrosion-suppressing element that is different from the primary bonding metal.
