摘要

Thin layer element has a covering layer (6) having a higher conductivity in the contact regions (8) in a direction perpendicular to a surface than in the functional regions (7) lying in a random direction. Preferred Features: The specific conductivity of the covering layer is isotropic or anisotropic. The covering layer in the contact regions deviates from a value in the functional regions. The covering layer consists of a first insulating partial layer which has openings extending over its entire layer thickness, and a second insulating partial layer which has non-connected islands closing the openings in the first partial layer.
