Abstract
Description
本願は、2013年11月29日に出願された日本特許出願「特願2013-247267」に基づく優先権を主張すると共に、参照によりその内容を組み込む。
特許文献3および4は、メタクリル酸アルキル共重合体、非反応性有機ケイ素化合物で表面処理された無機充填剤、および変性シリコーン樹脂を含有するサイドフィル材を開示している。
図1AおよびBは、半導体素子の実装において発生したブリードを説明する図である。ここでは、基板1の上に半導体素子2をアンダーフィル剤により接合した例を示している。図1Aはチップ上面から見た図を示している。図1Bは図1AのA-A断面を示している。半導体素子2の周辺に、アンダーフィル剤UF(封止剤)が盛られている部分(以下「フィレット」という)がある。その外側に発生しているのがブリードである。ブリードは外観上、変色して見えるだけでなく、装置の特性および信頼性に影響を与える場合がある。
本発明のエポキシ樹脂組成物は、(A)エポキシ樹脂と、(B)硬化剤と、(C)小径シリカフィラーと、(D)大径シリカフィラーとを含む。
3-1.エポキシ樹脂組成物の調整
表1~4は、実施例1~25および比較例1~6で、封止剤として用いられたエポキシ樹脂組成物の組成を示す。また、これらの表は、後述する、封止剤としてのエポキシ樹脂組成物の評価結果をも示す。表1~4において、エポキシ樹脂組成物の組成は、等量比を除いて、質量%で表されている。
実施例1~25および比較例1~6で用いられたエポキシ樹脂組成物について、以下の評価を行った。
試料としてソルダーレジスト(PSR4000 AUS703)付きの有機基板(FR-4基板)を用いた。まず試料を150℃で1時間、乾燥させた。次にこの試料をプラズマ処理した。プラズマ処理の条件は以下のとおりである。
ガス種:Ar
ガス流量:21sccm
供給電力:400W
処理時間:300sec
ブルックフィールド回転粘度計を用いて、50rpmで、25℃における、上記エポキシ樹脂組成物の粘度を測定した。
5rpmおよび50rpmで、上記エポキシ樹脂組成物の粘度を測定した。測定された5rpmにおける粘度の値を50rpmにおける粘度の値で除した値をTI値とした。
110℃において、20μmのギャップ(間隙)に上記エポキシ樹脂組成物を注入した。注入されたエポキシ樹脂組成物が入口から20mmの位置に到達するまでの時間を測定した。到達までの時間が短いほど注入性が良いことを示している。なお、注入性の欄にある「×」の記載は、エポキシ樹脂組成物が20mmの位置まで到達しなかったこと(すなわち不良であること)を意味する。
FR-4上に上記封止剤としてのエポキシ樹脂組成物(評価用試料)を約0.5mgポッティングした。この封止剤上に2mm角シリコンチップを載せた。この状態で、シリコンチップを室温で5min放置した。その後、送風乾燥機を用いて、150℃で120分の条件で、封止剤を硬化させた。このようにして得られた試験片について、接着強度を卓上型強度測定機(アイコーエンジニアリング(株)製1605HTP)を用いて測定した。なお、10回の測定により得られた測定値の平均値を検査値とした。
