Laser-assisted two-step glass wafer metallization: An experimental procedure to improve compatibility between glass and metallic films
Original language description
We report a simple and efficient two-step experimental procedure of glass metallization using laser microstructuring at ambient conditions. An adhesive pattern was created on the glass substrate using a laser, which imposes mechanical interlocking. An adhesive Cu layer was deposited on the glass substrate by magnetron sputtering and then electroplated with a functional Cu layer. Due to the unique surface structure created on the glass using laser, we achieved a thick layer of Cu metal film with high adhesion strength, well-defined grains and grain boundaries, and low surface roughness. The total thickness of the grown film was 11.4 µm, with an average surface roughness of 1.2 µm. The magnetron-sputtered coating did not show delamination from the glass substrate at a critical load of 60 N. The proposed method of glass metallization will lead to the realization of glass-based circuit materials that can be used in high-frequency electronic devices. Also, this procedure will be an alternative to chemical-based copper plating, which involves multiple processing steps and high-cost chemicals.
