Description
図1及び図2は、それぞれ本発明の実施の形態1に係る高周波高出力デバイスを示す斜視図及び断面図である。図3及び図4は、それぞれ本発明の実施の形態1に係る高周波高出力デバイスの内部を示す斜視図及び平面図である。
図9は、本発明の実施の形態2に係る高周波高出力デバイスを示す断面図である。本実施の形態では、ベース板1の実装部1aとフランジ部1bの間において、V溝13aがベース板1の上面のみに設けられている。V溝13aはCu板12に設けられ、その深さはMo板11まで達していても達していなくてもよい。また、V溝13aの形状はU字や凹形状などでもよく、形状にはこだわらない。このV溝13aを起点にフランジ部1bが曲がり易くなるため、実施の形態1と同様の効果を得ることができる。
図10は、本発明の実施の形態3に係る高周波高出力デバイスを示す断面図である。本実施の形態では、ベース板1の実装部1aとフランジ部1bの間において、V溝13a,13bがベース板1の上面と下面の上下異なる位置に設けられている。V溝13a,13bはそれぞれCu板10,12に設けられ、その深さはMo板11まで達していても達していなくてもよい。また、V溝13a,13bの形状はU字や凹形状などでもよく、形状にはこだわらない。
図11は、本発明の実施の形態4に係る高周波高出力デバイスを示す断面図である。本実施の形態では、ベース板1のフランジ部1bにおいて、上面側のCu板12が全て除去され、Mo板11と下面側のCu板10のみで構成されている。これにより、フランジ部1bが曲がり易くなるため、実施の形態1と同様の効果を得ることができる。
図12は、本発明の実施の形態5に係る高周波高出力デバイスを示す断面図である。図13は、本発明の実施の形態5に係る高周波高出力デバイスのベース板を構成するMo板とCu板を示す平面図である。
