Description
図11において、1,2はIGBTチップ、3,4はダイオードチップ、5はコレクタ導体、6はゲート導体、7は絶縁基板、8は金属ベース板である。図示のように、IGBTチップのコレクタとダイオードチップのカソードを電気的に接着したコレクタ導体5と、金属ベース板8との間が絶縁基板7によって絶縁され、IGBTチップのエミッタとダイオードチップのアノードが、ワイヤボンディングによって接続されている。
したがって、この発明の課題は、半導体チップの発生損失やスイッチング時間の増大を抑え、高耐圧大容量化を可能にすることにある。
前記パワー半導体チップを複数個直列に接続し、複数個同時にスイッチングさせるに当って、前記各半導体チップの等価的な出力容量のばらつきをなくすために、前記絶縁基板の少なくとも1枚の厚さ、または面積、もしくは誘電率の少なくとも1つの物理的特徴を、他の絶縁基板に対して異ならせることを特徴とする。
これは、1200V耐圧の半導体チップ(VCE1=VCE2=VCE3=VCE4=1200V)を4直列2並列に接続し、4500V耐圧に適う電力用半導体モジュールとした例である。すなわち、1,2,9,10,16,17,23,24は1200V耐圧のIGBTチップ、3,4,11,12,18,19,25,26は1200V耐圧のダイオードチップ、5,13,20,27はコレクタ導体、6,14,21,28はゲート導体、7,15,22,29は絶縁基板、8は金属ベース板である。ここで、絶縁基板15,22の厚さは、絶縁基板7,29より厚いものを用いている。
そして、図1の各IGBTチップのゲート端子に、ゲート導体を介して同時タイミングのゲート信号を入力し、各半導体チップを同時にスイッチングさせることにより、電力用半導体モジュールの見かけ上の耐圧は4800V(1200V×4直列)となり、4500V耐圧に充分適う電力用半導体モジュールを得ることができる。
以上のことから、この発明では、発生損失やスイッチング時間を低減した高耐圧大容量の電力用半導体モジュールを実現でき、さらには電力用半導体モジュール内の各半導体チップ間の電圧アンバランスを抑制することができる。
これは、各半導体チップの等価的な出力容量のばらつきをなくすために、絶縁基板の面積を互いに異ならせた例で、具体的には絶縁基板15,22には絶縁基板7,29よりも面積の狭い(小さい)ものを使用した例である。その他は図1と同様なので、詳細は省略する。
これは、各半導体チップの等価的な出力容量のばらつきをなくすために、絶縁基板の誘電率を互いに異ならせた例で、具体的には絶縁基板15,22には絶縁基板7,29よりも誘電率の小さいものを使用した例である。その他は図1と同様なので、詳細は省略する。
これは、各半導体チップの等価的な出力容量のばらつきをなくすために、上記の実施の形態を組合わせた例で、具体的には絶縁基板29を標準として、絶縁基板7は面積、絶縁基板15は誘電率、絶縁基板22は厚さを示す物理的特徴をそれぞれ異ならせたものである。その他は図1と同様なので、詳細は省略する。
この発明は、電圧駆動型半導体チップのみを直列接続した場合、またはダイオードチップのみを直列接続した場合にも適用可能なことは云うまでもない。
Claims (1)
- 電圧駆動型半導体チップとこれに逆並列接続されるダイオードチップとを組として絶縁基板上に搭載したパワー半導体チップを、金属ベース板上に搭載して構成される電力用半導体モジュールにおいて、
