Abstract
【解決手段】 ICチップ搭載用のチップ台座12、逆Fアンテナ11及び接地電極13が一体形成されたリードフレーム10にICチップ20を搭載して封止樹脂40でモールドする。この時、逆Fアンテナ11の共振部11aの開放端11dと接地電極13の先端部13aで形成されるギャップGの部分は,封止樹脂40によるモールドを行わずに窓Wとして開口させておく。これにより、窓Wで空気中にさらされたアンテナの開放端11dから効率良く電波を輻射することができる。また、一般的な半導体装置とほぼ同様の構造であるので、量産性に優れて安価に製造することができる。
【選択図】 図1
Description
ICチップ20の高周波入出力パッド21から2.4GHz帯の高周波信号が出力されると、金ワイヤ31を介して逆Fアンテナ11の給電部11cにこの高周波信号が供給され、共振部11aが励振される。共振部11aの底部に接続された接地部11bは、この共振部11aに直交しているので、共振長Lには寄与しない。また、共振部11aの開放端11dを除き、ほとんどの部分が封止樹脂40でモールドされているので、アンテナの空気中への露出部分を考慮した実効誘電率を用いることなく、この封止樹脂40の比誘電率と高周波信号の周波数のみで、共振長Lが定まる。
このアンテナ内蔵半導体装置は、図1と同様に逆Fアンテナを内蔵したアンテナ内蔵半導体装置の電波輻射用の窓の部分に、外部アンテナを接続するためのコネクタを設けたものである。例えば、アンテナ内蔵半導体装置を小型の機器に高密度実装した場合等で、配置の都合上、このアンテナ内蔵半導体装置の窓から電波を効果的に輻射できないことがある。このような場合、窓にコネクタを設けて同軸ケーブルを介して外部アンテナに接続することにより、目的を達成することができる。しかしながら、コネクタ等の接続端で反射や漏洩輻射の問題が起こりやすい。実施例2は、接続端での反射や漏洩輻射を抑制するためのコネクタに関するものである。
まず、外部アンテナが接続された同軸ケーブル70のおす型誘電体コネクタ60を、アンテナ内蔵半導体装置に設けられためす型の誘電体コネクタ60に差し込む。これにより、アンテナ内蔵半導体装置の逆Fアンテナの共振部の開放端が、めす型の誘電体コネクタ50の出力電極51とおす型誘電体コネクタ60の同軸出力電極61を介して、同軸ケーブル70の中心導体71に接続される。また、アンテナ内蔵半導体装置の接地電極の先端部は、めす型の誘電体コネクタ50の接地電極52とおす型誘電体コネクタ60の同軸接地電極62を介して、同軸ケーブル70の外部導体72に接続される。更に、アンテナ内蔵半導体装置の窓の裏側は、めす型の誘電体コネクタ50に設けられた誘電体ガイド53と、これに差し込まれたおす型誘電体コネクタ60の誘電体ガイド63によって隙間無く塞がれる。
