Definitions
- the present invention relates to a resin composition, an adhesive or sealant containing the resin composition, a cured product thereof, and a semiconductor device and an electronic component containing the cured product.
- curable resin compositions are often used for the assembly and mounting of components used in semiconductor devices and electronic components, such as semiconductor chips, in order to maintain reliability.
- adhesives and sealants used in the manufacture of such devices and components are required to exhibit sufficient curing properties even under low-temperature conditions.
- curable compositions that use a thiol-based curing agent as a curing agent are known (for example, Patent Documents 1 and 2).
- thermal stress is generated in each of the parts according to the thermal expansion coefficient of the material. Because the thermal stress is not uniform due to the difference in the thermal expansion coefficient, it is not offset and causes deformation of the assembly.
- the stress associated with this deformation acts particularly on the joints between the parts, i.e., the cured adhesive, and in some cases can cause the joints to peel off or cracks to form in the cured adhesive. Such peeling and cracks are particularly likely to occur when the cured adhesive is brittle and lacks flexibility. Therefore, adhesives for bonding parts made of different materials need to be flexible enough to follow the deformation of the assembly caused by the thermal stress of the parts, i.e., they need stress relaxation properties after curing.
- Patent Document 3 discloses an epoxy resin composition capable of providing a cured product that can follow the deformation of a substrate, the epoxy resin composition comprising (A1) a first epoxy resin that is liquid at 25°C and has an epoxy equivalent of 250 to 1000, (A2) a second epoxy resin that has an epoxy equivalent lower than that of the first epoxy resin, (B) a thiol compound that has two or more thiol groups in the molecule, and (C) an inorganic filler.

本実施形態の樹脂組成物は、(D)硬化触媒(以下、「成分(D)」とも言う)を含む。成分(D)を用いることにより、本実施形態の樹脂組成物を低温条件下でも短時間で硬化させることができる。本実施形態において用いる硬化触媒は、成分(A)及び成分(B)の多官能エポキシ化合物の硬化触媒であれば特に限定されず、公知のものを使用することができる。
本実施形態の樹脂組成物は、(E)分子中に不飽和二重結合とそれに隣接する電子吸引性基とを含む基(e)(以下、単に「基(e)」とも言う)を1つ有する単官能化合物(以下、「成分(E)」とも言う)を含む。本実施形態において、成分(E)中の基(e)、より具体的には基(e)中の不飽和二重結合は、(C)多官能チオール化合物中のチオール基と反応する。本明細書中において、成分(E)について、チオール基と反応する基(e)を分子中に1つ有することを意味して「単官能」との用語を用いる。電子吸引性基の例としては、カルボニル基やシアノ基が挙げられ、カルボニル基が好ましい。
また、本実施形態に係る樹脂組成物について、例えば80℃での硬化反応条件においてDSC測定すると、成分(E)を含まないものと比較して、総発熱量が小さい。エポキシ-チオールの反応は、エポキシの開環反応に起因する反応熱が生じるのに対し、成分(E)の反応は、開環を伴わないため、発熱量が低下したと考えられる。これにより、短時間硬化における被着体及びその周辺部材の過熱を抑制可能である。
また、成分(E)は、単官能であるため、架橋を形成せず、架橋密度が高くなりすぎることによる硬化物の内部応力上昇を抑制することができ、得られる樹脂組成物の硬化物に柔軟性を与えることができる。

(1)オンセット温度
各樹脂組成物をDSC用アルミパンに5mg入れ、蓋をしたのち、蓋に孔をあけ、示差走査熱量計(DSC、NETZSCH製:DSC204 F1 Phoenix(登録商標))にて窒素雰囲気下、25℃から250℃まで5℃/minで昇温する過程のDSC曲線を求めた。得られたDSC曲線に複数のオンセット温度が観察された場合には、低温側の値をオンセット温度とした。これを表1に示す。
上記試験により得られたオンセット温度は反応性を示しており、反応性が高いほどオンセット温度は低温である。比較例1~3に比べて実施例1~20はオンセット温度が低く、反応性が高いことが分かる。オンセット温度は85℃以下であることが好ましく、83℃以下であることがより好ましく、80℃以下であることがさらに好ましい。
(2)発熱ピーク面積
上記(1)オンセット温度を求める際に得たDSC曲線のデータから、解析ソフト(NETZSCH Proteus-Thermal Analysis バージョン8.0.2)を用いて発熱ピーク面積を算出した。これを表1に示す。
上記試験により得られたDSC曲線における発熱ピーク面積は、樹脂組成物が硬化中に発する熱量を表し、面積が小さいほど発熱量が小さく、短時間硬化における周辺部材の過熱を抑制可能である。DSC曲線における発熱ピーク面積は420J/g以下であることが好ましく、350J/g以下であることがより好ましく、300J/gであることがさらに好ましい。
また、実施例1~20の樹脂組成物と、成分(B)及び成分(E)を含まない比較例1の樹脂組成物と、成分(B)を含まず、かつ成分(E)の代わりに成分(E’)を含む比較例2の樹脂組成物との比較により、成分(E’)を含むことにより、発熱ピーク面積が大きくなるのに対し、成分(E)を含むことにより、発熱ピーク面積が小さくなること、がわかる。
本明細書に記載された全ての文献、特許出願、および技術規格は、個々の文献、特許出願、および技術規格が参照により取り込まれることが具体的かつ個々に記された場合と同程度に、本明細書に参照により取り込まれる。
