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 state.
good high temperature solders, which are used as die attach materials, are required to be soft for the relaxation of thermal stress, and should be thermally conductive for eﬀective heat dissipation. pb sn alloys, containing over 85mass%pb,1–3) have been commonly used in die attach bonding as high temperature solders.
