Newly developed copper sulfate plating chemicals for wiring of semiconductor wafers.
Okuno Pharmaceutical Industry has newly developed the "TORYZA LCN" series of copper sulfate plating additives, which are optimal for semiconductor wafer re-wiring and copper pillar formation. TORYZA LCN FRV is an electro-copper plating additive that excels in film thickness uniformity and is ideal for pattern formation in re-wiring. TORYZA LCN SP is an electro-copper plating additive that is optimal for forming copper posts and copper pillars on semiconductor wafers and package substrates. TORYZA LCN SV is best suited for micro bumps and trench filling for silicon interposers. TORYZA LCN SD is an electroplating additive for semiconductors that excels in the embedding of blind via holes and trenches. Okuno Pharmaceutical Industry offers numerous plating process proposals tailored to your needs for wafers.
