(H)成分の充填剤は必要に応じて配合してもよい任意成分であり、この(H)成分は前記(D)成分の酸化亜鉛粒子以外の充填剤(無機質充填剤及び/又は有機樹脂充填剤)であり、この組成物に十分な機械的強度を与えるために使用される。(H)成分の充填剤としては公知のものを使用することができる。例えば微粉末シリカ、煙霧質シリカ、沈降性シリカ、これらのシリカ表面を有機ケイ素化合物で疎水化処理したシリカ;ガラスビーズ;ガラスバルーン;透明樹脂ビーズ;シリカエアロゲル;珪藻土、酸化鉄、酸化チタン、煙霧状金属酸化物などの金属酸化物;湿式シリカあるいはこれらの表面をシラン処理したもの;石英粉末、タルク、ゼオライト及びベントナイト等の補強剤;アスベスト、ガラス繊維、炭素繊維、炭酸カルシウム、炭酸マグネシウム、炭酸亜鉛などの金属炭酸塩;ガラスウール、微粉マイカ、溶融シリカ粉末、ポリスチレン、ポリ塩化ビニル、ポリプロピレンなどの合成樹脂粉末等が使用される。上記に例示する充填剤のうち、シリカ、炭酸カルシウム、ゼオライトなどの無機質充填剤が好ましく、特に表面を疎水化処理した煙霧質シリカ、炭酸カルシウムが好ましい。なお、(H)成分の充填剤には、前述の(D)成分として定義される所定の平均粒子径を備える酸化亜鉛は包含されない。
本発明の熱伝導性シリコーン組成物は、上記(A)~(H)成分に加えて、更に(I)下記一般式(4)で表される直鎖状ジオルガノポリシロキサン(いわゆる無官能性シリコーンオイル)を必要に応じて任意成分として配合してもよい。
本発明の熱伝導性シリコーン組成物には、熱伝導性シリコーン組成物の劣化を防ぐために、2,6-ジ-tert-ブチル-4-メチルフェノール等の従来公知の酸化防止剤を必要に応じて配合してもよい。更に、チクソ性付与剤、染料、顔料、難燃剤、沈降防止剤、チクソ性向上剤等を必要に応じて配合することができる。
本発明の熱伝導性シリコーン組成物は、従来の熱伝導性シリコーン組成物に比べ高い熱伝導率を有し、かつ厚さ10μm以下への圧縮性が良好なものである。
本発明の熱伝導性シリコーン組成物の製造方法について説明する。
本発明の熱伝導性シリコーン組成物の製造方法は、上述した本発明の熱伝導性シリコーン組成物を製造する方法であって、前記(A)、(B)、(C)、(D)、(E)及び(F)成分を混合する工程を有することを特徴とするものである。
具体的には、上記(B)成分、又は(A)及び(B)成分と、(D)成分を上記のように混合する工程と、これに少なくとも(C)、(E)及び(F)成分、必要に応じてその他任意成分を混合する工程とを含むことが好ましい。
また、上記(B)成分、又は(A)及び(B)成分と、(D)成分を混合する工程の際に100℃以上の温度で30分以上混合することで、(D)成分が(B)成分によって十分に表面処理され、経時での熱抵抗の悪化を抑えることができる。
本発明の半導体装置は、絶縁ゲートバイポーラトランジスタ(IGBT)などの発熱体と冷却体との間に形成された厚み10μm以下の間隙に本発明の熱伝導性シリコーン組成物が層状に充填され、この組成物層が前記発熱体と冷却体とを熱的に介在していることを特徴とするものである。本発明の熱伝導性シリコーン組成物は厚さ10μm以下まで圧縮される。これにより従来の熱伝導性シリコーン組成物と比較して、冷却効率の向上が期待できる。
代表的な構造の断面図を図1に示すが、本発明はこれに限定されるものではない。
冷却体3は、熱伝導のよい材料からなる冷却フィン(平板及び平板の一方の主面に設けられた放熱用の突起からなるもの)であることが好ましい。
絶縁層3aは、冷却体3(冷却フィン)の熱伝導性シリコーン組成物層2が設けられる面(冷却フィンの平板)上に形成された、窒化ケイ素、窒化アルミニウム、ダイヤモンドなどの熱伝導性のよい絶縁材料からなる厚さ10~1,000μmの薄膜である。
また、熱伝導性シリコーン組成物層2は、発熱体1(IGBT)の裏面側と冷却体3(冷却フィン)の平面側との間の間隙に、本発明の熱伝導性シリコーン組成物が層状に設けられたものである。熱伝導性シリコーン組成物層2の厚さは10μm以下であり、0.5~10μmの範囲にあることが好ましく、0.5~5μmにあることがより好ましい。
このような半導体装置の構成とすることにより、発熱体1で発生した熱は熱伝導性シリコーン組成物層2を介して冷却体3に伝わり、外部へ放熱され、図1の場合は冷却体3と接する冷却水4へ放熱される。
