Southeast Asia’s first semiconductor-grade polysilicon plant powered by clean energy is set to be built in Sarawak, Malaysia.
The International Finance Corporation (IFC), a member of the World Bank Group, announced on March 30 that it will extend a loan of up to USD 125 million to OCI TerraSus (OCI TRS), the Malaysian subsidiary of South Korea’s OCI Holdings. The financing will support the construction of an advanced chip material facility, which is expected to begin commercial operations in 2029.
Why the World Bank is backing OCI’s expansion?
According to the IFC, the project marks its first investment in Sarawak and aims to strengthen Malaysia’s role in the global semiconductor supply chain while creating jobs. It will also support OCI TRS in enhancing its environmental, social and governance (ESG) standards and management systems.
Unlock the full article to explore three key takeaways:
- Southeast Asia's first semiconductor-grade polysilicon plant is confirmed for Sarawak; IFC is providing a USD 125M loan with commercial operations targeted for 2029.
- Sarawak achieved its renewable energy capacity target 5 years ahead of schedule, with hydropower accounting for ~70% of its energy mix — a key draw for clean manufacturing investment.
- OCI TRS will form a joint venture with Japan's Tokuyama Corp., targeting semiconductor-grade polysilicon — a higher-purity, higher-value product than solar-grade.
