摘要: A method is described for patterned depositions of a material onto a substrate. A surface of a polymeric substrate is first etched so as to form an etched layer having enhanced adhesions characteristics and then selected portions of the etched layer are removed so as to define a pattern having enhanced and diminished adhesion characteristics for the deposition of a conductor onto the remaining etched layer. In one embodiment, a surface of a PTFE substrate is chemically etched so as to improve the adhesion of copper thereto. Thereafter, selected portions of the etched surface are irradiated with a laser beam so as to remove the etched selected portions of the etched surface and form patterns of enhanced and diminished adhesion of copper thereto.
