ABSTRACTA Fluorocarbon resin surface was selectively modified by irradiation with a ArF laser beam through a thin layer of NaAlO2, B(OH)3, or H2O solution to give a hydrophilic property. As a result, with low fluence, the surface was most effectively modified with the NaAlO2 solution among the three solutions. However, the contact angle in this case changed by 10 degrees as the fluence changed only 1mJ/cm2. When modifying a large area of the surface, high resolution displacement could not be achieved because the laser beam was not uniform in displacing functional groups. Thus, the laser fluence was successfully made uniform by homogenizing the laser beam; the functional groups were replaced on the fluorocarbon resin surface with high resolution, which was successfully modified to be hydrophilic by distributing the laser fluence uniformly.

AbstractCircuit patterned nucleation of copper atoms onto polyimide surface was demonstrated by using ArF excimer laser (λ =193nm) and copper sulfate aqueous solution at an atmospheric pressure. Photo-excited C-H bonds of the polyimide surface were effectively dehydrated with hydrogen atoms which were photodissociated from the water. The dangling bonds of the dehydrated hydrogen atoms were combined with the oxygen and the copper atoms which were photodissociated by copper-sulfate aqueous solution. Thus, C-O-Cu bonds were formed on the surface. After this copper substitution, it was carried out onto the nucleated parts by usual electroless plating at 70°C. In this process, the conductive circuit pattern Cu thin film was deposited on polyimide surface.
