実施例、比較例で得られた封止用樹脂組成物を、表面粗さRaが15nmのGaAsテストピース表面に円面積10mm2となるように塗布し、175℃、4時間熱処理して、GaAsテストピースと高さ3mmの硬化物とからなる試験片を得た。自動ダイシェア測定装置(ノードソン・アドバンスド・テクノロジー社製、DAGE4000型)を用いて、前記GaAsテストピース表面からのテスターの距離0.125mm、当該テスターの速度0.3mm/secにて、260℃温度下にてGaAsテストピースと硬化物とのせん断強度(ダイシェア強度)を測定した。
前記条件1で得られた試験片を、温度85℃、湿度85%で24時間吸湿させ、吸湿後の当該試験片において、条件1と同様にGaAsテストピースと硬化物とのせん断強度(ダイシェア強度)を測定した。
低圧トランスファー成形機(コータキ精機社製、KTS-15)を用いて、ANSI/ASTM D 3123-72に準じたスパイラルフロー測定用金型に、金型温度175℃、注入圧力6.9MPa、保圧時間120秒の条件にて、封止用樹脂組成物を注入し、流動長を測定した。
スパイラルフローは、流動性のパラメータであり、数値が大きい方が、流動性が良好である。
各例で得られた封止用樹脂組成物の矩形流路圧(矩形圧)を次のように測定した。
まず、封止用樹脂組成物(粉砕物)を、プランジャー(プランジャーサイズφ18mm)内で、175℃で3秒間加熱して予備加熱して軟化させた。
低圧トランスファー成形機(NEC社製、40tマニュアルプレス)を用いて、金型温度175℃、注入速度24.7mm/secの条件にて、幅13mm、厚さ0.5mm、長さ175mmの矩形状の流路に、上記で得られた、軟化した封止用樹脂組成物を注入した。このとき、流路の上流先端から25mmの位置に埋設した圧力センサーにて圧力の経時変化を測定し、封止用樹脂組成物の流動時における最低圧力(kgf/cm2)を測定し、これを矩形圧とした。矩形圧は、溶融粘度のパラメータであり、数値が小さい方が、溶融粘度が低いことを示す。
175℃に設定されたホットプレート上に、各実施例または比較例の封止用樹脂組成物を置いた。試料が溶融した後、ヘラで練りながら、硬化するまで(ヘラで練ることができなくなるまで)の時間を測定した。
ゲルタイムが短いほど、硬化速度が速いことを示す。
各実施例および比較例について、得られた封止用樹脂組成物の硬化物のガラス転移温度(Tg)、線膨張係数(CTE1、CTE2)を、以下のように測定した。まず、低圧トランスファー成形機(コータキ精機(株)製「KTS-15」)を用いて金型温度175℃、注入圧力6.9MPa、硬化時間120秒で封止用樹脂組成物を注入成形し、10mm×4mm×4mmの試験片を得た。次いで、得られた試験片を175℃、4時間で後硬化した後、熱機械分析装置(セイコー電子工業(株)製、TMA100)を用いて、測定温度範囲0℃~320℃、昇温速度5℃/分の条件下で測定を行った。この測定結果から、ガラス転移温度(Tg)、ガラス転移温度以下における線膨張係数(CTE1)、ガラス転移温度超過における線膨張係数(CTE2)を算出した。
各実施例または比較例の封止用樹脂組成物を打錠成形してタブレットを得た。得られたタブレットを、トランスファー成形機を用いて、金型温度175℃、注入圧力9.8MPa、硬化時間120秒の条件で封止用樹脂組成物を注入成形し、幅10mm×厚さ4mm×長さ80mmの硬化物を得た。その後、得られた試験片を175℃、4時間で後硬化し、評価用の試験片を得た。得られた試験片の、室温および260℃における曲げ弾性率を、JIS K 6911に準じて測定した。
各実施例および比較例について、得られた封止用樹脂組成物の成形収縮率を測定した。測定は、低圧トランスファー成形機(コータキ精機(株)製「KTS-15」)を用いて金型温度175℃、注入圧力6.9MPa、硬化時間120秒の条件で作製した試験片に対して、JIS K 6911に準じて行った。
(MSL評価用の半導体装置の作製)
各種性能評価のために、次のようにして半導体装置を作製した。後述の評価のため、各実施例/比較例において、12個ずつの半導体パッケージを作製した。
(1)GaAsチップ(長さ4mm×幅4mm、厚み0.35mm)を、表面がAgによりめっきされたリードフレームのダイパッド部上に搭載した。
(2)(1)で得られた構造体を、低圧トランスファー成形機を用いて、金型温度175℃、注入圧力10.0MPa、硬化時間2分の条件で、各実施例または比較例の封止用樹脂組成物を用いて封止成形し、半導体パッケージを作製した。
(3)その後、得られた半導体パッケージを175℃、4時間の条件で後硬化し、半導体装置を得た。
まず、得られた半導体装置12個を、85℃相対湿度60%の環境下に168時間放置した。その後、IRリフロー処理(260℃)を行った。
処理後の半導体装置内部を、超音波探傷装置で観察した。そして、全ての半導体装置において、封止樹脂と、GaAsチップと、の界面において剥離が生じなかった場合を○、半導体装置の1個でも界面に剥離が生じた場合を×とした。
