TSMC supports the "responsible sourcing" practice advocated by the Electronic Industry Citizenship Coalition (EICC) and the Global e-Sustainability Initiative (GeSI), and adopts their jointly developed Conflict-Free Smelter Program (CFSP) to require and help our suppliers to source conflict-free minerals. Meanwhile, we have implemented a series of compliance safeguards in accordance with industry leading practices...
The thriving development of Taiwan's semiconductor industry is attributed not only to the joint efforts of Taiwan Semiconductor Industry Association (TSIA) members, but also to the strong logistical support of supply chain vendors. Enhancing the occupational safety and health of supply chain employees is a material issue that TSMC is deeply concerned about. As a result, TSMC actively formulates management...
TSMC held its 17th annual Supply Chain Management forum on Dec. 7, 2017 to show appreciation for the support and contributions of its suppliers over the past year, particularly in 10nm capacity ramp and technology development in 7nm and beyond. Over 700 suppliers around the world in the fields of equipment, materials, packaging, testing, facilities, IT systems and services, and environmental and waste management...
