Eutectic bonding depends on a formation of an eutecticum in the bond interphase. This makes bonding of two substates by use of eg. a AuSi eutecticum possible at temperatures much lower than the actual melting points of either of the two (in this case bonding can be done at around 390<sup>o</sup>C). The bonding strecth is quite good, but far from as good as anodic bonding. Different eutectica have a different eutectic (bonding) temperature | Eutectic bonding depends on a formation of an eutecticum in the bond interphase.
