Abstract
A laser, such as an excimer laser, is employed to ablate electroless plating activator material from polymer and other substrates. The treated substrates are then immersed in electroless plating baths for plating of conductive material over remaining activator material. The method is particularly effective for depositing conductive patterns on non-flat substrates and on substrates needing plated-through connections. High resolution patterns are created on any compatible polymer substrate with any compatible electroless plating activator material.
