发明名称 Underfill composition and semiconductor device and manufacturing method thereof
摘要 To provide a solid preapplication underfill material that has excellent workability, has a high degree of freedom for solder bonding processes, and enables the formation of a solder bond with high reliability. (Resolution Means) The underfill composition of the present disclosure contains a hardened epoxy resin and has a viscosity of 1000 Pa·s or more at 30° C. The hardening epoxy resin includes a crystalline epoxy resin at not less than 50 wt % relative to an entire resin composition.
