Exclusive: EnterpriseSG positions Singapore's semiconductor SMEs for bigger roles in global chip supply chains

Singapore's play isn't SME support—it's strategic positioning in the "glue layer" of advanced packaging and silicon photonics as the AI bottleneck shifts from fabrication to integration. With CoWoS capacity locked by TSMC and UCIe standards still fragmenting, value is migrating to TSV, micro-bump, and CPO substrate work—processes demanding two decades of precision manufacturing, not EUV lithography. That's precisely where local SMEs sit. If silicon photonics displaces copper interconnect at 800G and beyond, the chain restructures: upstream silicon waveguide etching, downstream CPO test and assembly. A Singapore SME that nails small-batch, high-yield, reliability-validated output becomes an irreplaceable node in Broadcom's or Intel's supply chain. Competitive read: ASE and SPIL (Taiwan, China) compete on volume; Amkor on US compliance; Singapore on neutrality plus precision. Expect 2-3 Western IDM acquisitions of local packaging SMEs within 18 months, with CPO lines clustering in E1/E2. Risk vector: if hybrid-bonding equipment enters export-control scope, SME capex gets squeezed; a price war from Taiwan, China OSATs could compress margins below 15%.
