概要(目的・用途・実施内容)/ Abstract (Aim, Use Applications and Contents)

The sputtering and structuring of magnetic thin films for flexible sensors was studied. The processes were optimized to achieve high sensor effect.

実験 / Experimental

Experiments to sputter soft magnetic thin films (FeCuNbSiB) with different conditions were performed. The properties of the films were studied and sputtering conditions optimized. A lift-off process to structure thick films (>1um) was done and tested. Substrates with a laminated PI film were prepared. On the PI film the magnetic films were sputtered and structured. After removing the PI film from the substrates a flexible bended sensor prototype was made and measured. (Fig. 1)

結果と考察 / Results and Discussion

It was successfully shown, that sensors can be made on flexible PI with sputtered magnetic metallic film. (Fig. 2)
