Patent ID: 8623450

Claim:
A method for producing a flexible planar circuit configuration (FS) having multiple layers forming a layer sequence (SF), in which an intermediate/adhesive layer (HS) is created on a substrate surface (OS) of a rigid substrate (SW), at least one first insulating layer (N 1 ) is created over the substrate (SW) with the intermediate/adhesive layer (HS), at least one first conductive layer is created over the first insulating layer (N 1 ), a conductive structure (L 1 ) is created in at least the at least one conductive layer, a flexible planar circuit configuration (FS) comprising the at least one first insulating layer (N 1 ), the at least one first conductive layer and the conductive structure (L 1 ) is removed from the substrate (SW) after deposition of all layers, wherein: the intermediate/adhesive layer (HS) is created in such a way that at least one inner area (ZB) and an edge area (RB surrounding the inner area (ZB) are defined on the substrate surface (OS) of the substrate (SW), the intermediate/adhesive layer (HS) being only provided outside the inner area (ZB), the first insulating layer (N 1 ) of a layer sequence (SF) comprised by the intermediate/adhesive layer (HS), the at least one first insulating layer (N 1 ) and at least one first conductive layer, is created over the inner area (ZB) and the edge area (RB) such that the first insulating layer (N 1 ) has a stronger adhesion with respect to the substrate (SW) over the edge area (RB) than over the inner area (ZB), and the flexible planar circuit configuration (FS) is created directly over the inner area (ZB) of the substrate (SW) with no adhesive layer in between, whereby the flexible planar circuit configuration (FS) can be easily detached from the substrate (SW), because the inner area (ZB) over which the flexible planar circuit configuration (FS) is formed is not adhered to the substrate (SW) by the intermediate/adhesive layer (HS).
