Problems solved by technology

However, such a polymer or copolymer of a butadiene compound has a good compatibility with other resins by containing a functional group, but on the other hand, the viscosity of the raw material itself becomes high
When such a raw material is used in a die attach material, if it is added in an amount that exhibits good solder crack resistance, the viscosity of the resin composition becomes high, which causes deterioration of coating workability such as stringiness
In order to further improve the performance of semiconductor devices, the demand for higher performance of die-attach materials is also increasing. There is no die-attach material that satisfies both solder crack resistance and coating workability, and it is urgently desired to achieve high-level solder reflow resistance. Die attach material with excellent performance and coating workability

Abstract

The present invention provides a resin composition having excellent coating workability while imparting reliability, including resistance to solder reflow, to a semiconductor device when used as a die attachment material or an adhesive for a heat-radiating member. This resin composition contains: a polymer or a copolymer of a conjugated diene compound having at least one functional group; a thermosetting resin; and a (meth)acrylic polymer or copolymer having a reactive functional group capable of reacting with other reactive groups.

Description

technical field [0001] The present invention relates to a resin composition and a semiconductor device. [0002] this application claims priority based on Japanese Patent Application No. 2011-017747 for which it applied to Japan on January 31, 2011, and uses the content here. Background technique [0003] In recent years, as part of environmental measures, the removal of lead from semiconductor products has progressed, and lead-free solders have begun to be used when mounting semiconductor components on substrates. When such lead-free solder is used, the solder reflow temperature becomes higher than that of conventional tin-lead solder. Therefore, as a die-attach material for bonding semiconductor elements such as ICs to supports such as metal frames or organic substrates, it is desired that peeling is less likely to occur during solder reflow than before, that is, it can sufficiently withstand the temperature of solder reflow. As the internal stress of semiconductor compo...
