Description
詳細には、上述のような構成または実装のそれぞれでは、従来のプレーナ実装と比較して、浮遊インダクタンスがきわめて低くなる。一例として、状況によっては、先行技術の解決策と比べて約5分の1に減少されるなど、モジュール基板の浮遊インダクタンスがきわめて低くなり得る。
本発明によると、少なくとも第1の基板はダイレクトボンド銅基板(DBC基板)を基材としている。ダイレクトボンド銅基板は、たとえば通常アルミナから形成されるセラミックタイル、または他の上述の基板材料を主成分として構成され、片面または両面に銅シートが高温酸化プロセスによって接着されている。セラミックタイルは基板主要層として機能し、銅は基板金属被覆として機能する。銅をPCB技術を用いてエッチングして電気回路を形成可能である。そのような基板は、形成がとりわけ容易であり、さらに、モジュールの熱挙動について利点を有する。これとは別に、特にDBC基板は広い応用範囲およびモジュールの形成に関する設計の応用について利点を示している。詳細には、DBC基板を所望の適用範囲に容易に応用可能である。したがって、上述のようなパワー半導体モジュールをきわめて容易に形成および応用可能である。
