Layer structure for delivering at least one active ingredient

Layer structure for delivering at least one active ingredient, having the layer structure: - a supporting substrate (100) - a plurality of active areas (101) spaced from each other are applied to the carrier substrate (100) and contain the at least one active ingredient, each of said active areas (101) (102) of the carrier substrate surrounded completely by non-drug occupied intermediate areas, - a semi-permeable outer layer (103) formed on the supporting substrate (100) and the active regions thereon (101) is applied and both the active regions (101) and the non-drug occupied intermediate areas (102) of the carrier substrate is covered, wherein the semi-permeable outer layer ( 103) (in the non-drug occupied intermediate portions 102) on the carrier (substrate 100) adhered directly or indirectly, wherein each of the active regions (101) is enclosed around the sides and from above (by the semi-permeable cover layer 103), so that the active substance depot form, and - said at least one drug through the semipermeable layer (103) therethrough can diffuse to the outside.
