Description
しかしながら、この導板を放熱に用いたパワーモジュールでは、上記従来の第1のパワーモジュールと同様に、ゲート電極をボンディングワイヤで接続する必要があり、プロセスの増加を招く。
筐体と、
上記筐体に固定され、その筐体と内部空間を形成し、内側の面に導体部が設けられた基材と、
上記基材の上記内側の面に実装された半導体素子と、
上記筐体内に配置され、絶縁体とこの絶縁体に固定された2本以上のリード端子とを有する内部配線構造体と
を備え、
上記半導体素子の上記基材に面する面と反対の側の面に設けられた電極と上記基材の上記導体部とを、上記内部配線構造体の上記リード端子を介して接続すると共に、
上記リード端子と上記半導体素子との間の半田厚を調整するため、上記絶縁体の上記リード端子が固定された側に、上記半導体素子に向かって突出して上記半導体素子に接する突出部を設けたことを特徴とする。
また、上記絶縁体のリード端子が固定された側に設けた突出部が、半導体素子に向かって突出して半導体素子に接することにより、リード端子と半導体素子との間の半田厚を調整するので、リフローしたときに突出部の下端が半導体素子の表面に接触する位置までしか半田が押しつぶされることがなく、ショートを防止できる。
上記筐体の開口部に配置され、外部に一部が露出した高熱伝導率の放熱部を有する蓋を備え、
上記蓋の上記放熱部と上記絶縁体が接する。
図1Aはこの発明の第1実施形態のパワーモジュールの断面図を示し、図1Bは上記パワーモジュールの半導体素子実装部分の上面図を示している。また、図1Cは図1Aに示すA部分のリフロー前の状態の拡大図を示し、図1Dは図1Aに示すA部分のリフロー後の状態の拡大図を示している。
図2はこの発明の第2実施形態のパワーモジュールの断面図を示している。
