Adhesive composition for bonding a semiconductor device

摘要

Described is an adhesive composition suitable for bonding a semiconductor device to a substrate comprising about 60-90 wt. % particulate silver; about 10-40 wt. % of an adhesive material comprising at least one nonelectrically conductive organic compound; and a filler comprising at least one electrically conductive organic compound capable of forming a conductivity bridge between silver particles. The adhesive composition may additionally include at least one curing catalyst for the adhesive material, a flexibilizer to render the composition more flexible, a surfactant to facilitate contact with a substrate and/or a material to aid in adjusting the rheology of the composition.
