Sarawak will construct Southeast Asia's first semiconductor-grade polysilicon manufacturing plant with US$125 million backing from the World Bank's International Finance Corporation, marking the region's ambitious push up the semiconductor value chain as global powers compete for chip supply dominance.
The IFC loan to OCI TerraSus Sdn Bhd, announced in late March, will finance a facility at Samalaju Industrial Park in Bintulu capable of producing 8,000 metric tonnes annually of ultra-high purity polysilicon—the critical material for silicon wafers and advanced chips. Commercial operations are targeted for January 2029.
The project, a joint venture between South Korea's OCI Holdings and Japan's Tokuyama Corporation, represents more than industrial expansion. It positions ASEAN as a player in semiconductor upstream production, an area long dominated by China, the United States, and Japan.
Sarawak's Hydropower Advantage
Polysilicon production is extraordinarily energy-intensive, requiring high temperatures and ultra-clean manufacturing environments. Sarawak's abundant hydroelectric power from the Bakun and Murum dams provides a critical competitive edge: cheap, renewable electricity that makes semiconductor-grade production economically viable while meeting sustainability requirements.
The state has positioned itself as Malaysia's energy hub, offering industrial users rates well below regional averages. That advantage has attracted heavy industry, and now it's pulling in high-tech manufacturing. The Samalaju park already hosts a solar-grade polysilicon plant; the new facility will produce material of even higher purity, suitable for chips rather than solar panels.
ASEAN Climbs the Chip Ladder
The Sarawak plant fits a broader regional pattern. Vietnam has expanded semiconductor assembly and testing, attracting Intel and Samsung investments. Singapore dominates chip design and advanced manufacturing through GlobalFoundries and other players. Now Malaysia enters upstream materials production.
This diversification matters as the U.S. and China wage a tech cold war. Washington has restricted China's access to advanced chip technology while building supply chains through allies. ASEAN nations, maintaining strategic autonomy, position themselves as neutral suppliers willing to work with all sides—a lucrative but delicate stance.
