Abstract

A curable composition includes an epoxy monomer component and an aniline-based hardener. The epoxy monomer component is a first component formed from a first epoxy monomer represented by Formula (I), or a second component including the first epoxy monomer represented by Formula (I) and a second epoxy monomer different from the first epoxy monomer represented by Formula (I), wherein each of the substituents in Formula (I) is given the definitions as set forth in the Specification and Claims. Based on 100 wt % of the epoxy monomer component, an amount of the first epoxy monomer represented by Formula (I) is not smaller than 25 wt % and less than 100 wt % and an amount of the second epoxy monomer is greater than 0% and not greater than 75 wt %. A cured product formed from the curable composition, and a method for encapsulating a semiconductor device using the curable composition are also provided.

Dependent claims

A curable composition, comprising:

an epoxy monomer component selected from one of a first component and a second component, the first component being formed from at least one of a first epoxy monomer represented by Formula (I), the second component including the at least one of the first epoxy monomer represented by Formula (I) and at least one of a second epoxy monomer that is different from the first epoxy monomer represented by Formula (I),
wherein based on 100 wt % of the epoxy monomer component, the first epoxy monomer represented by Formula (I) is present in an amount of not smaller than 25 wt % and less than 100 wt % and the second epoxy monomer is present in an amount of greater than 0 wt % and not greater than 75 wt %,
wherein
each of R1, R22 and R3 is independently a C1-C3 alkylene group,
R21 is one of a single bond and oxygen, and
each of R4, R5 and R6 is independently one of hydrogen and a C1-C3 alkyl group;
and
at least one of an aniline-based hardener.
