Disclosed is a method of manufacturing a flexible conductive track arrangement for a neurostimulation system such as a cochlear implant device. The method allows for the arrangement to be manufactured without the need for a transfer substrate by embedding the metal structures of the arrangement in a ceramic dielectric material formed in an atomic layer deposition process which can be performed at a temperature that is compatible with the polymer processing steps of such an arrangement. A flexible conductive track arrangement and a neurostimulation system are also disclosed.
