Description



As a gold-based eutectic solder, gold-germanium alloy has a melting point of 361°C. Gold-germanium eutectic solder has the advantages of low vapor pressure, low contact resistance, good adhesion to the substrate, high electrical conductivity and thermal conductivity. It is considered to be an ideal sputtering and evaporation source and is widely used in GaAs In MESFET (GaAs Metal Semiconductor Schottky Junction Field Effect Transistor), an M/S system with a different composition from Au, Ni and other metals is used to form ohmic contacts.

Gold-germanium alloy and gold-germanium alloy as a kind of eutectic solder has also been used in the field of chip bonding and packaging, and it is widely used as low-melting solder for transistors, integrated circuits and other components.
