Patent ID: 8129217

Claim:
A process for the production of a multi-layer body having at least one electronic component, wherein the multi-layer body includes at least two electrical functional layers, on a top side of a carrier substrate, which are structured in register relationship with each other, wherein an underside of the carrier substrate is prepared in such a way that in a first region the result is a transparency which is increased in relation to at least one second region for a first exposure radiation and in the at least one second region the result is a transparency which is increased in relation to the first region for at least one second exposure radiation which is different in relation thereto in register relationship with the first region, the underside is successively exposed with the first and the at least one second exposure radiation and the first exposure radiation is used for structuring a first functional layer and the at least one second exposure radiation is used for structuring at least one second functional layer on the top side of the carrier substrate.
