Abstract:
PURPOSE: A conductive paste for bonding semiconductor chips is provided to replace wiring boding of high costs, to have excellent productivity and durability, and to have excellent reliability and coupling rate. CONSTITUTION: A conductive paste for bonding semiconductor chips comprises a conductive powder and binder. The binder includes 30-65 wt% of an epoxy-based binder, 10-50 wt% of an acrylic binder, and 5-30 wt% of an elastomer-based binder. The glass transition temperature of the elastomer-based binder is (-80) - (-10)°C. The bonding method of the semiconductor includes the chip pad and substrate pad-bonding method by forming pattern between a chip pad(10) and a substrate pad(21).
