Description
以下の説明において、「アクティブ領域」とは半導体装置のオン状態において主電流が流れる領域であり、「終端領域」とは、アクティブ領域の周囲における領域であるものとする。また、以下において、「外側」とは半導体装置の外周に向かう方向であり、「内側」とは「外側」に対して反対の方向とする。また、以下の記載では、不純物の導電型に関して、N型を「第1導電型」、N型とは反対導電型のP型を「第2導電型」として一般的に定義するが、その逆の定義でも構わない。
図1は本発明に係る実施の形態1のダイオードモジュール200の終端領域とアクティブ領域の一部の構成を示す断面図であり、図2はダイオードモジュール200内に樹脂封止されたダイオードチップ100のチップ最外周領域を示す部分断面図である。なお、図2においては、便宜的に特徴的な構成だけを示している。
TEOS酸化膜:ヤング率80.1[Gpa]、線膨張係数9[ppm/℃]
ポリイミド:ヤング率5[GPa]、線膨張係数54[ppm/℃]
エポキシ樹脂:ヤング率16[GPa]、線膨張係数18[ppm/℃]
このように、ポリイミド膜6の下層膜としてパッシベーション膜4が形成され、パッシベーション膜4の端縁部はチップ最外周領域まで延在しているので、ダイオードチップ100に熱応力が加わった場合でも、半導体基板1よりもパッシベーション膜4の方がポリイミド膜6および樹脂封止材7と材料物性値が近いため、半導体基板1の歪みが減少し、さらにパッシベーション膜4自体が応力を受けた場合の緩衝膜として働くため、ポリイミド膜6の端縁部の半導体基板1内の応力が減少し、クラックの発生を抑制することができる。
図3は本発明に係る実施の形態2のダイオードチップ100Aのチップ最外周領域を示す部分断面図であり、図2と同様に便宜的に特徴的な構成だけを示している。
図4は本発明に係る実施の形態3のダイオードチップ100Bのチップ最外周領域を示す部分断面図であり、図2と同様に便宜的に特徴的な構成だけを示している。
図5は本発明に係る実施の形態4のダイオードチップ100Cのチップ最外周領域を示す部分断面図であり、図2と同様に便宜的に特徴的な構成だけを示している。
図6は本発明に係る実施の形態5のダイオードチップ100Dのチップ最外周領域を示す部分断面図であり、図2と同様に便宜的に特徴的な構成だけを示している。
図7は本発明に係る実施の形態6のダイオードチップ100Eのチップ最外周領域を示す部分断面図であり、図2と同様に便宜的に特徴的な構成だけを示している。
図8は本発明に係る実施の形態7のダイオードチップ100Fのチップ最外周領域を示す部分断面図であり、図2と同様に便宜的に特徴的な構成だけを示している。
図9は本発明に係る実施の形態8のダイオードチップ100Gのチップ最外周領域を示す部分断面図であり、図2と同様に便宜的に特徴的な構成だけを示している。
図10は本発明に係る実施の形態9のダイオードモジュール200Aのチップ最外周領域を示す部分断面図であり、図2と同様に便宜的に特徴的な構成だけを示している。
図11は本発明に係る実施の形態10のダイオードモジュール200Bのチップ最外周領域を示す部分断面図であり、図2と同様に便宜的に特徴的な構成だけを示している。
図12は本発明に係る実施の形態11のダイオードモジュール200Cのチップ最外周領域を示す部分断面図であり、図2と同様に便宜的に特徴的な構成だけを示している。
図13は本発明に係る実施の形態12のダイオードチップ100Hのチップ最外周領域を示す部分断面図であり、図2と同様に便宜的に特徴的な構成だけを示している。
以上説明した実施の形態1~12においては、半導体基板1をSi基板とし、ダイオードチップ100~100HはSi半導体装置として説明したが、半導体基板1を炭化珪素半導体基板などのワイドギャップ半導体基板とすることで、終端領域のサイズを縮小することができ、半導体装置の小型化が可能になる。
