Technological innovation to reduce transmission loss! Copper plating process on glass substrates.
Developed an electroless copper plating process that achieves high adhesion on glass substrates with low dielectric loss!
Glass has high smoothness and insulation properties, making it excellent for signal transmission characteristics, and it is gaining attention as an interposer material necessary for 2.5D implementation in semiconductor packaging. Various methods for forming adhesion layers, such as sputtering and sol-gel methods, have been researched to improve adhesion to glass materials. Our company has developed an electroless copper plating process called "PLOPX," which achieves high plating adhesion to glass substrates by using metal oxides deposited via Liquid Phase Deposition (LPD) as the adhesion layer. This process allows for all steps to be treated using wet methods.
