The melting point of an alloy of two (binary) or more metals depends on the relative … Eutectic bonding, also referred to as eutectic soldering, describes a wafer bonding technique with an intermediate metal layer that can produce a eutectic system. Those eutectic metals are alloys that transform directly from solid to liquid state, or vice versa from liquid to solid state, at a specific composition and temperature without passing a two-phase equilibrium, i.e. liquid and solid stat…
WebSince the eutectic temperature is typically much lower than the melting temperature of the substrates, it is considered to be low-temperature bonding. The most established eutectic system is between silicon and gold, and its eutectic temperature is known to be 363°C (eutectic composition being Au/Si=97.15/2.85 wt%). A gold layer can be ...
