Abstract
Description
図5は、特許文献1の半導体装置の電極構造を説明するための図である。
上述した図5に示した従来の半導体装置においては、入力側基板55上の入力用の整合回路とゲートパッド50とを接続するワイヤ59は、グランドプレートの露出部58を跨いで接続されるため、露出部58の幅に相当する分だけ長いワイヤ長を要することになる。この結果、ゲート電極の入力インダクタンスが大きくなり、共振周波数を低下させる欠点がある。このため、高い周波数での動作に対して整合回路が構成できなくなる。
図1は、本発明の第1の実施の形態に係る半導体装置の電極構造の平面図を示す。また、図2は、本発明の第1の実施の形態に係る半導体装置の一部の構成を説明するための斜視図を示す。
図3は、本発明の第2の実施の形態に係る半導体装置の電極構造を示す平面図を示す。また、図4は、本発明の第2の実施の形態に係る半導体装置の一部の構成を説明するための斜視図を示す。
上記のように、本発明は第1乃至第2の実施の形態によって記載したが、この開示の一部をなす論述および図面はこの発明を限定するものではない。この開示から当業者には様々な代替実施の形態、実施例および運用技術が明らかとなろう。
