Laser Assisted Pd Seeding For Electroless Plating On Siq2, A. G. Schrott, B. Braren, Ravi F. Saraf

Ravi Saraf Publications

Excimer laser pulses with wavelengths of 248 and 308 nm were used to selectively seed Pd on SiO₂ surfaces, making them suitable for electroless plating. This novel seeding process for insulating materials is accomplished with the sample immersed in the seeding solution, and occurs only on the areas of the substrate that are illuminated (through the liquid) by the laser light. The Pd content of the seeded samples increased with the number of pulses, but was rather independent of repetition rate. The deposition rate showed a dependence with wavelength consistent with a defect driven mechanism for electron excitation through …
