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.

Passivation layer structure

An electronic component is described and has a dielectric layer which is constructed on a substrate, conductive surfaces that are constructed on the dielectric layer, and an electrically conductive guard structure. The guard structure is disposed in a plane above the conductive surfaces such that the conductive surfaces are not completely covered by the guard structure.
