A METHOD OF MANUFACTURING A CIRCUIT CARRIER LAYER AND A USE OF SAID METHOD FOR MANUFACTURING A CIRCUIT CARRIER

摘要

In order to be able to produce high density circuits on a dielectric substrate wherein the conductor lines of said circuit have a good adhesion to the dielectric substrate surface, a method is provided which comprises the following method steps: a) providing an auxiliary substrate having two sides, at least one of said sides having an electrically conductive surface; b) treating at least one of the at least one electrically conductive surface with at least one release layer forming compound, the at least one release layer forming compound being a heterocyclic compound having at least one thiol group, c) forming a patterned resist coating on at least one of said at least one electrically conductive surface which has been treated with said at least one release layer forming compound, the patterned resist coating having at least one resist opening thereby exposing the electrically conductive surface; d) forming an electrically conductive pattern in the at least one resist opening by electrodepositing a metal on the exposed electrically conductive surface; e) embedding each electrically conductive pattern into a dielectric material by forming a respective dielectric material layer on the respective side of the auxiliary substrate; and f) separating each dielectric material layer comprising the respective embedded electrically conductive pattern and the auxiliary substrate from each other.
