Description

technical field [0001] The present invention relates to a resin composition for encapsulating semiconductor chips and a semiconductor device using the resin composition. Background technique [0002] Due to the well-balanced properties of epoxy resins in terms of productivity, cost, and reliability, epoxy resin compositions have been mainly used in packaging of semiconductor chips in recent years. As the size and thickness of semiconductor devices decrease, epoxy resin compositions for encapsulation with lower viscosity and higher strength are required. In addition, there is an increasing need to prepare a fire-resistant device that does not contain flame retardants such as Br compounds and antimony oxides in consideration of environmental factors. In view of this situation, the current research clearly tends to use less viscous resins and add more inorganic fillers to the epoxy resin composition. [0003] As a new trend, lead-free solders having a higher melting point tha...
