Module with thin-film circuit comprising a trimmable capacitor

摘要

The invention relates to a module provided with a thin-film circuit which comprises an integrated trimmable capacitor. At least one electrically conducting layer (2, 4) of the capacitor has a structured surface with recesses. This finger-type design has the result that the actual capacitor is composed of several capacitors connected in parallel. After the total capacitance value has been determined, this total capacitance value can be fine tuned through a selective cutting-off of fingers, i.e. of capacitors, from the main surface of the electrically conducting layer (2, 4).
