This invention relates to a process for improving the adhesion of copper circuitry to a dielectric layer and a method for forming a multilayer printed circuit board wherein the copper circuitry of the board is covered with a layer of an oxide, hydroxide, or combination thereof of a metal selected from the group consisting of tin, bismuth, lead, indium, gallium, germanium, and alloys of said metals, wherein the metal is deposited on the copper circuitry by using an aqueous electroless plating solution. An organosilane bonding mixture is applied between the metal oxide/hydroxide layer and the polymeric dielectric layer.
本发明涉及一种提高铜电路与介电层粘合力的工艺和一种形成多层印刷电路板的方法,其中电路板的铜电路上覆盖有一层选自锡、铋、铅、铟、镓、锗和上述金属合金的金属氧化物、氢氧化物或其组合的氧化物层,金属是通过使用无电解电镀水溶液沉积在铜电路上的。在金属氧化物/氢氧化物层和聚合电介质层之间使用有机硅烷键合混合物。
