Abstract
An assembly that includes a first substrate, a second substrate, and a stress mitigation layer disposed between the first and the second substrates. The stress mitigation layer is directly bonded onto the second substrate, and the second substrate is separated from the intermetallic compound layer by the stress mitigation layer. The stress mitigation layer has a high purity of at least 99% aluminum such that the stress mitigation layer reduces thermomechanical stresses on the first and second substrates. The assembly further includes an intermetallic compound layer disposed between the first substrate and the stress mitigation layer such that the stress mitigation layer is separated from the first substrate by the intermetallic compound layer.
