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. |

1. An underfill composition comprising:
a hardening epoxy resin comprising a crystalline epoxy resin of not less than about 50 wt % relative to an entire resin composition, wherein the hardening epoxy resin has a viscosity of about 1000 Pa·s at 30° C., wherein the crystalline epoxy resin is a biphenyl epoxy resin with a molar weight of not more than about 500; and an inorganic filler having about 100 parts by mass relative to about 100 parts by mass of the entire resin composition. |
