Description
図7は、半導体基板上に形成されたコイルの具体例を示す図である。図7に示すように、半導体基板100の表面に金属パターン(例えば銅や金の薄膜パターン)によって渦巻き形状のコイル110が形成される。コイル110を半導体基板100の表面に形成することにより、コイルを含んで構成される発振器等の全部品を半導体基板110上に一体形成して、外付け部品をなくすことができるため、部品点数の低減や工程の簡略化が可能になり、大幅にコストを削減することが可能になる。
図1は、本実施形態の半導体装置を示す平面図である。また、図2は図1に示す半導体装置の部分的な斜視図である。これらの図に示すように、本実施形態の半導体装置10は、矩形形状の半導体基板12と、この半導体基板12の4箇所の角部近傍に形成された複数のパッド20と、角部以外の各辺に沿った周辺領域に形成された複数のパッド30と、隣接するパッド20間を接続するボンディングワイヤ40とを含んで構成されている。
図6は、半導体基板12上に2種類のコイルが形成された半導体装置10Cの概略的な構成を示す平面図である。図6に示すように、半導体基板12の表面を2つの領域に分割した場合を想定し、各分割領域の周辺に沿って別々にボンディングワイヤを形成することにより、2種類のコイルが形成することが可能になる。これらのコイルの用途としては、一方をアンテナ用コイルとして使用し、他方をインダクタ用コイルとして使用する場合や、一方を送信用のアンテナ用コイルとして使用し、他方を受信用のアンテナコイルとして使用する場合等が考えられる。
