Epoxy resin curing accelerator |
| abstract |
In an epoxy resin composition for semiconductor encapsulation, curing acceleration can be achieved by lowering the melt viscosity of the composition to increase liquid flowability, while increasing initial hardness at the time of curing and improving demoldability. Provide the agent. Epoxy resin curing acceleration comprising a quaternary phosphonium (A) represented by the general formula (1) and a phenol resin (B) providing a phenoxide ion as an anion corresponding thereto. Agent. [Chemical 1] [Wherein, R1 to R5 each independently represents a hydrogen atom, a linear or branched alkyl group having 1 to 4 carbon atoms, or an alkoxy group having 1 to 4 carbon atoms. ] [Selection figure] None |
