Abstract
【解決手段】磁気角度センサは半導体チップ6と、半導体チップ6の表面に配置される平らな形状の少なくとも2つの磁場集中装置7、8を含む。4つのホール・センサ9、10,11,12は半導体チップ6において一体化され、それぞれの端の領域に磁場集中装置7,8が配置される。それらは、磁場集中装置7,8の端の領域において半導体チップ6の表面にほぼ垂直に延長する磁場の磁力線によって広げられる。2つのホール・センサ9、11は、磁場の第1の構成要素を測定するためのセンサの第1の対を形成し、他の2つのホール・センサ10、12は、磁場の第2の構成要素を測定するためのセンサの第2の対を形成する。同じ磁場集中装置7,8の端の領域に配置されるホール・センサを連結する連結線は単一の共通の線13を形成する。
