Abstract:
Methods include selectively depositing a phase change resist having high light transmittance onto a dielectric to form a pattern, etching away portions of the dielectric not covered by the resist and depositing a metal seed layer on the etched portions of the dielectric. A metal layer is then deposited on the metal seed layer by light induced plating.
