Description
電気抵抗たとえば電流センサ抵抗を基板上に取り付けることは知られている。これはたとえば厚膜技術およびLTCC技術(LTCC = Iow temperature cofire ceramic)により行われる。この目的で銀パラジウムペーストがスクリーン印刷法により基板上に印刷される。殊に導体路抵抗として形成されたとえば100mΩの典型的な抵抗値とたとえば100ppm/kの温度係数値をもつ抵抗を集積するためには煩雑なプロセスが必要とされ、たとえばこの抵抗と銀含有度の高い低抵抗の導体路との接続などを行わなければならず、これと同時に中間合金(中間生成物intermediate)の取り付けも必要とされ、このことから余分な印刷ステップと熱処理ステップが必要となる。このような余分なステップは、製造ラインの設計に起因してまったく不可能であることも多い。まえもって混合された抵抗であるスクリーン印刷された銀パラジウムペーストは、抵抗を製造するために焼成処理され、つまり熱処理される。
基板上に抵抗未加工品が取り付けられ、次にこの抵抗未加工品が熱処理されて抵抗が形成される形式の、本発明による電気抵抗たとえば電流センサ抵抗を基板上に製造する方法によれば、抵抗未加工品を形成するため、基板上にパラジウム層が取り付けられ、次にこのパラジウム層の上に銀層が取り付けられる。択一的に、基板上に銀層が取り付けられ、この銀層の上にパラジウム層が取り付けられる。その後、熱処理が行われ、これによってパラジウム層のパラジウムと銀層の銀とが完全に合金化される。このようにして得られた合金は、望ましい抵抗たとえば電流センサ抵抗を成すものである。
図1には電気的に絶縁性の材料から成る基板1が示されており、基板1の表面2に電気抵抗3たとえば電流測定抵抗4が配置されている。この図面では抵抗3が抵抗未加工品5としても示されており、これはあとで述べる処理ステップによって抵抗3に変えられる。ここで用語「電流センサ抵抗」ないしは「電流検知抵抗」とは、この抵抗により電流が捕捉されることを意味するものであり、そのようにして電流の流れに関する情報を取得することができる。
