Recycling & Refining in Semiconductor Manufacturing
Precious metals used in semiconductor manufacturing (e.g., Au, Pt, Pd, Ru) are rare and environmentally intensive to mine. TANAKA Precious Metals promotes sustainability by recovering and refining these materials from production residues and used components.
･Collection targets: Sputtering residues, plating solutions, bonding wires, probe pins, etc.
･Refining: Proprietary technologies ensure ultra-high purity (99.999%+) suitable for semiconductor use
･SDGs contribution
– Goal 12: Circular resource use
– Goal 13: CO₂ reduction through decreased mining
This approach supports the semiconductor industry with stable supply, cost efficiency, and environmental responsibility.
