Abstract
Description
図1は、本発明の実施の形態1に係る半導体装置を示す断面図である。図2は、本発明の実施の形態1に係る半導体装置の内部を示す平面図である。この半導体装置は、周波数1GHz以上、1W以上の電力を出力する。
図3は、本発明の実施の形態2に係る半導体装置の内部を示す平面図である。本実施の形態では、DCバイアスを通すリード端子13とヒートシンク1との間に誘電体14が個別に設けられている。接着機能を持つ誘電体14をリード端子13の裏面に接着し、この誘電体14を介してリード端子13をヒートシンク1に接着させる。リード端子13は誘電体14によりヒートシンク1に固定され、ワイヤ15により半導体チップ2に接続されている。これにより、高周波信号を通すリード端子5,6以外の端子についても、ワイヤボンド性が改善し、リードフレームとヒートシンク1をより強固に固定することができる。その他の構成及び効果は実施の形態1と同様である。
図4は、本発明の実施の形態3に係る半導体装置の内部を示す平面図である。電極部16,17が、高周波信号を通すリード端子5,6の側面からそれぞれ突出している。電極部16,17の形状は特に問わない。電極部16とヒートシンク1との間の誘電体10、電極部16、及びヒートシンク1によりコンデンサが構成されている。電極部17についても同様である。
図5は、本発明の実施の形態4に係る半導体装置を示す断面図である。図6は図5のI−IIに沿った断面図である。封止樹脂12の上面が凹型形状に成型されている。なお、封止樹脂12の上面を凸型形状に成型してもよい。この凹部を含む封止樹脂12の表面全面に金属膜18が形成されている。金属膜18は、GNDとなるヒートシンク1又はリード端子に接続されている。これにより、高周波信号を通すリード端子5,6は、上下がGNDシールドで囲われたストリップラインのような構造となる。従って、リード端子5,6から漏洩する電磁波が少なくなり、かつ外部からの電磁波の影響を受けにくくなるため、GaNデバイスの特性を安定化することができる。また、リード端子5,6の上に配置される封止樹脂12の厚みを調整してリード端子5,6と金属膜18との距離を最適化することで、特性インピーダンスの設計自由度を増やすことができる。
図7は、本発明の実施の形態5に係る半導体装置を示す断面図である。図8は、本発明の実施の形態5に係るリード端子を拡大した上面図である。図9は、本発明の実施の形態5に係るリード端子を拡大した下面図である。リード端子19,20は、1枚の金属体ではなく、上面金属21、誘電体22、及び下面金属23,24の3層構造である。
