IPC: H01L21/60
Filed: 1979-01-31
Abstract: PURPOSE: To improve the bonding strength of a silver bump electrode by forming an alminum-silver electrode by the continuous evaporation of aluminum and silver  on a semiconductor substrate maintained at 150W200°C.  
     CONSTITUTION: Protective film 2 is formed on the surface of semiconductor substrate 1. This is heated to 150W200°C, and Al and Ag are continuously evaprated on it, and thereby it is coated with thin Al film 3 and Ag film 5. Subsequently, the Ag film is removed by etching. Then, by sintering, semiconductor substrate 1 and thin Al film 3 are caused to react with each other to form eutectic 6 of ohmic character. At this time, the alloying of thin Al film 3 and thin Ag film 5 takes place and thereby alloy layer 7 is formed.
