Claim:
1. A method for providing a releasable substrate on a carrier, the method comprising: providing the carrier-with a bonding layer of radiation curable adhesive ( selectively irradiating a first area subsection of the bonding layer with a first radiation dose per unit area for selectively at least partially curing the first area subsection, wherein a second area subsection of the bonding layer is not irradiated or irradiated with a second radiation dose per unit area that is less than the first radiation dose per unit area such that the first area subsection is more cured than the second the area subsection; providing a substrate and bringing the substrate in contact with the first area subsection and the second area subsection; curing the second area subsection in contact with the substrate for forming an adhesion area between the second area subsection and the substrate; wherein the first area subsection forms a release area, an adhesion force between the bonding layer and the substrate being lower in the release area than in the adhesion area as a result of the first area subsection being more cured than the second area subsection prior to being in contact with the substrate.
