Description
図1は実施の形態1に係る半導体装置を示す断面図である。基板1の上にトランジスタチップ2がフリップチップ実装されている。トランジスタチップ2は、高周波特性・高放熱に優れた窒化ガリウム系HEMTなどの電界効果トランジスタである。トランジスタチップ2の上方にCu又はAu等を含む放熱性の高い放熱基板3が配置されている。トランジスタチップ2と放熱基板3はAuバンプ4により電気的に接続されている。なお、フリップチップ実装を用いない場合は、Auバンプ4の代わりにワイヤボンドを用いてもよい。
図6は実施の形態2に係るトランジスタチップの能動領域の封止状態を示す断面図である。図7は実施の形態2に係るトランジスタチップの能動領域の封止状態を示す上面図である。最もソースドレイン間容量Cdsの増加に寄与すると考えられるゲート電極13の周辺を誘電率の小さい第2の封止材6で覆うことで高周波特性の低下を抑制することができる。また、面積の大きいオーミック電極であるソース電極11及びドレイン電極12の周辺を熱伝導率の大きい第1の封止材5で覆うことで放熱性が向上するため、信頼性を確保できる。その他の構成は実施の形態1と同様である。
図8は実施の形態3に係るトランジスタチップの能動領域の封止状態を示す断面図である。図9は実施の形態3に係るトランジスタチップの能動領域の封止状態を示す上面図である。発熱源であるゲート電極13の周辺を熱伝導率の大きい第1の封止材5で覆うことで放熱性が向上するため、信頼性を確保できる。また、ソース電極11及びドレイン電極12の周辺を誘電率の小さい第2の封止材6で覆うことでソースドレイン間容量Cdsを抑制することができるため、高周波特性の低下を抑制することができる。その他の構成は実施の形態1と同様である。
