Abstract
A conductor layer is patterned into flat portions, for example of a fingerprint sensor that effects capacitive measurement. The conductor layer is fragmented in a lattice-like manner by cutouts so that an applied passivation layer rests on a base layer that is present beneath the conductor layer. The interlaminar shear strength of the passivation is increased in this way.
