Description
実質的に銀を含まない裏面メタライゼーション層を使用することにより、裏面メタライゼーション層内に通常ある銀のエレクトロマイグレーションを防止することができ、これにより銀のエレクトロマイグレーションによりしばしば引き起こされる短絡を減少させることによってパワーモジュールの信頼性を高めることができる。
[0013]本明細書に組み込まれそして一部を形成する添付の図面は、本開示のいくつかの態様を図説し、そして説明とともに本開示の原理を説明するように働く。
リッジパワーモジュールであることを、当業者なら認識するであろう。しかしながら、本開示は、そのようには限定されない。本明細書において説明する原理を、任意の数または構成に配置されたより多くのまたはより少ないスイッチング素子を含むパワーモジュールなど、任意の構成のパワーモジュールに適用してもよい。さらに、パワーモジュール10のトランジスタデバイスがMOSFETとしてでは説明されるが、任意のタイプのトランジスタデバイスを、本明細書における原理から逸脱せずにパワーモジュール10で使用する場合がある。例えば、絶縁ゲート型バイポーラトランジスタ(IGBT)を、いくつかの実施形態では第1のMOSFET Q1および第2のMOSFET Q2の代わりに置き換えてもよい。同様に、第1のダイオードD1および第2のダイオードD2は、本明細書において説明する原理から逸脱せずに任意のタイプのダイオードであってもよい。例えば、第1のダイオードD1および第2のダイオードD2は、ショットキーダイオード、ショットキーバリアダイオード(SBD)であってもよい、またはそれどころか上に説明した第1のMOSFET Q1および第2のMOSFET Q2の内蔵型ボディダイオードとして設けられる場合がある。その結果、第1のダイオードD1が第1のMOSFET Q1と統合され、第2のダイオードD2が第2のMOSFET Q2と統合される。第1のダイオードD1が第1のMOSFET Q1の内蔵型ボディダイオードにより形成されないときでさえ、第1のダイオードD1を、いくつかの実施形態では同じ半導体ダイ上に第1のMOSFET Q1とともにモノリシックに集積してもよい。同様に、第2のダイオードD2が第2のMOSFET Q2の内蔵型ボディダイオードにより形成されないときでさえ、第2のダイオードD2を、いくつかの実施形態では同じ半導体ダイ上に第2のMOSFET Q2とともにモノリシックに集積してもよい。
と第3の端子18Cとの間に並列に結合されるときには、これらのサブモジュールは、第2のMOSFET Q2および第2のダイオードD2を実効的に形成する。
ニッケルの除去を含む。パッシベーション層積層体48は、図面の展開部に示したように多数のパッシベーション層52を含む。注目すべきことに、多数のパッシベーション層52は交互の層である。すなわち、パッシベーション層52のうちの第1の層が第1の組成を有し、パッシベーション層52のうちの第2の層が第1の組成とは異なる第2の組成を有し、そしてこれらの層が示したように交互である。1つの実施形態では、パッシベーション層52は、窒化ケイ素(SiN)、二酸化ケイ素(SiO2)、酸窒化ケイ素(SiON)の間で交替させる。さらに、パッシベーション層52を、交替する様式というよりはパターンで設けてもよく、その結果、3層毎に、4層毎になどが異なる組成となる、または材料組成が繰り返しの様式で3つ以上の材料の間で変化する。このようにしてパッシベーション層52を交替させるまたはパターン化することは、これらの層の堆積において生じる何らかの欠陥が異なる組成を有する引き続く層により分断されることを確実にする。したがって、ピンホールおよびクラックが、パッシベーション層積層体48の全体を貫通して形成するはずがなく、これにより腐食および剥離から半導体ダイ16の下にある部分を保護する。さらに、いくつかのパッシベーション層52を形成することは、パッシベーション層積層体48の全体の厚さを大きくし、これがさらなる環境の保護を与え、そしてパッシベーション層52のうちの複数のものが半導体ダイ16に故障を生じさせずに剥離するようになるまたはそうでなければ損傷するようになることを可能にする。1つの実施形態では、パッシベーション層積層体48は、少なくとも1.6μmの厚さである。様々な実施形態では、パッシベーション層積層体48は、1.6μmと10μmとの間の厚さであってもよい。具体的に、パッシベーション層積層体48は、少なくとも2.0μmの厚さ、少なくとも2.5μmの厚さ、そして少なくとも3.0μmの厚さであってもよい。さらに、パッシベーション層積層体48は、少なくとも5層のパッシベーション層52、少なくとも7層のパッシベーション層52、少なくとも9層のパッシベーション層52、少なくとも15層のパッシベーション層52、少なくとも20層のパッシベーション層52、そして本開示の原理から逸脱せずに数百層に至るまでのパッシベーション層52を含んでもよい。パッシベーション層積層体48内のパッシベーション層52の厚さは、同じであってもよいし、任意の所望のパターンで変わってもよい。上に論じたようなパッシベーション層積層体48を形成することは、パワーモジュール10の丈夫さを著しく高めることができる。
