(方法)
低圧トランスファー成形機を用いて、金型温度170℃、注入流量177mm3/秒の条件にて、幅15mm、厚さ1mm、長さ175mmの矩形状の流路に、前記封止用樹脂組成物を注入し、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、前記封止用樹脂組成物の流動時における最低圧力(MPa)を測定し、これを矩形圧とする。

また、以上のような特性は、本実施形態の封止用樹脂組成物を構成する各成分の種類、配合量を適切に調整することで達成することができる。

これにより、電子装置としての耐湿信頼性や耐リフロー性を向上させることができる。また、基材の反りの一層の抑制に寄与しうる。
本実施形態の封止用樹脂組成物は、充填材(C)を含む。
充填材(C)として具体的には、シリカ、アルミナ、チタンホワイト、水酸化アルミニウム、タルク、クレー、マイカ、ガラス繊維等の無機充填剤が挙げられる。
充填材(C)の平均粒径は、特に限定されないが、典型的には1~100μm、好ましくは1~50μm、より好ましくは1~20μmである。平均粒径が適当であることにより、硬化時の適度な流動性を確保すること等ができる。なお、平均粒径を比較的小さくする(例えば1~20μm)ことで、例えば、最先端のウエハーレベルパッケージにおける狭いギャップ部分への充填性を高めることも考えられる。
充填材(C)の平均粒径は、レーザ回折/散乱式粒子径分布測定装置(例えば、株式会社堀場製作所製の湿式粒度分布測定機LA-950)により体積基準の粒子径分布のデータを取得し、そのデータを処理することで求めることができる。測定は、通常、湿式で行われる。
表面修飾のためのカップリング剤としては、後述のカップリング剤(E)として挙げているもの等を用いることができる
充填材(C)の含有量は特に制限が無いが、例えば、封止用樹脂組成物の全固形分100質量%に対して65質量部%以上98質量部%以下含まれることが好ましく、68質量部%以上95質量部%以下含まれることがより好ましく、70質量部%以上93質量部%以下含まれることが特に好ましい。充填材(C)の含有量を適度に多くすることにより、低吸湿性などを向上させ、電子装置の耐湿信頼性や耐リフロー性をより効果的に向上させることができる。特に、充填材(C)を適度に多くして、相対的に樹脂成分(エポキシ樹脂(A)や硬化剤(B)など)を少なくすれば、理論上は硬化収縮が少なくなるため、反りを一層低減しうる。充填材(C)の含有量を適度に少なくすることにより、成形時の流動性の低下にともなう成形性の低下等を抑制することが可能となる。本実施形態の樹脂組成物によれば、充填材(C)を適度に多くしても、成形時の流動性の低下等を抑制することが可能となる。
本実施形態の封止用樹脂組成物は、硬化促進剤を含むことができる。硬化促進剤は、熱硬化性樹脂の硬化を促進させるものであればよく、熱硬化性樹脂の種類に応じて選択される。

また、封止用樹脂組成物のハンドリングを向上させる観点から、封止用樹脂組成物中の硬化促進剤の含有量は、封止用樹脂組成物全体に対して好ましくは5質量%以下であり、より好ましくは3質量%以下、さらに好ましくは1質量%以下である。
本実施形態の封止用樹脂組成物は、カップリング剤を含むことができる。封止用樹脂組成物がカップリング剤を含むことにより、例えば、基材との密着性の更なる向上や、組成物中での充填材の分散性の向上などを図ることができる。充填材の分散性が向上すると、最終的に得られる硬化物の均質性が向上する。これは硬化物の機械的強度の向上などに寄与しうる。
より具体的には、以下を例示することができる。

(流動性(スパイラルフロー))
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、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、上記で得られた半導体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ーであり、数値が大きい方が、流動性が良好である。単位はcmである。
175℃としたホットプレート上に各実施例・比較例の封止用エポキシ樹脂組成物からなる試料を置き、試料が溶融後、へらで練りながら硬化するまでの時間を測定した。この時間が短いほど、硬化速度が速いことを示す。
結果を表2に示す。
実施例および比較例のそれぞれの封止用エポキシ樹脂組成物について、樹脂封止(ASM:as Mold)を行った後、本硬化させて樹脂封止基板を作製することを想定した加熱条件(PMC:Post Mold Cure)で収縮率を評価した。まず、円盤状の金型の室温における寸法を4箇所測定し、その平均値を算出した。続けて、金型に封止用エポキシ樹脂組成物を投入して円盤状の硬化物を得、得られた硬化物に熱処理を施した後の室温における直径を、当該金型で測定した箇所に対応する4箇所で測定し、その平均値を算出した。次に、得られた平均値を、次式:〔(室温における金型寸法-熱処理後の硬化物の室温における寸法)/室温における金型寸法〕×100(%)に当てはめて、硬化物の収縮率Sn(%)を算出した。
結果を表2に示す。樹脂封止を想定した温度条件は、175℃、120秒、本硬化を想定した温度条件は175℃、4時間とした。
硬化物の熱時弾性率は、JISK-6911に準じて以下の方法で測定した。まず、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、この試験片をDMA測定装置(セイコーインスツルメンツ社製)を用いた3点曲げ法により、測定温度範囲0℃~300℃,5℃/minで昇温測定し、25℃での硬化物の常温時弾性率、及び、260℃での硬化物の熱時弾性率を測定した。なお、単位は、MPaである。
低圧トランスファー成形機(日本電気(株)製40tマニュアルプレス)を用いて、金型温度170℃、注入流量177mm3/秒の条件にて、幅15mm、厚さ1mm、長さ175mmの矩形状の流路に、上記で得られた半導体封止用樹脂組成物を注入し、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、半導体封止用樹脂組成物の流動時における最低圧力を測定した。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。
各実施例および各比較例について、得られた半導体封止用樹脂組成物の硬化物のガラス転移温度および線膨張係数を、次のように測定した。まず、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3分で半導体封止用樹脂組成物を注入成形し、15mm×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(α1)、ガラス転移温度以上における線膨張係数(α2)を算出した。α1は、40℃~80℃における線膨張係数、α2は、190℃~230℃における線膨張係数とした。結果を表2に示す。表2中、α1とα2の単位はppm/℃であり、ガラス転移温度の単位は℃である。
低圧トランスファー成形機を用い、金型温度175℃、注入圧力6.9MPa、硬化時間2分で実施例・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。この半導体装置は、ボールグリッドアレイ(BGA)パッケージ(樹脂封止部分サイズ:35mm×35mm×厚み1.2mm)であり、チップサイズは7mm×7mmである。また、ワイヤーは金線であり、ワイヤー径が20μm、平均ワイヤー長さが5mmである。得られた半導体装置各4パッケージを175℃、4時間で後硬化し、室温に冷却後、パッケージのゲートから対角線方向に、表面粗さ計を用いて高さ方向の変異を測定し、変異差の最も大きい値を反り量とし、4パッケージの反り量の平均値が150μm未満を○、150μm以上を×と判定した。
また、実施例の封止用樹脂組成物を用いた半導体パッケージについて、さらに260℃、10分の条件でリフロー処理を実施したところ、リフロー処理後の4パッケージの反り量の平均値は150μm未満であることを確認した。
パッケージ反り量の評価で成形したBGAパッケージを軟X線透過装置で観察した。ワイヤー流れ量の計算方法としては、1個のパッケージの中で最も流れた(変形した)ワイヤーの流れ量を(F)、そのワイヤーの長さを(L)として、流れ量=F/L×100(%)を算出し、4パッケージの平均値が5%未満を○、5%以上を×と判定した。
