Singapore is one of the world's most important semiconductor manufacturing and design hubs, accounting for around 10% of global semiconductor output and 20%+ of global semiconductor equipment exports. The ecosystem spans wafer fabrication, IC design, OSAT (outsourced assembly & test), EDA tools, and specialised equipment suppliers — concentrated in the EDB-anchored Tampines, Woodlands, and Pasir Ris wafer-fab parks.
This page groups semiconductor providers with a verified Singapore presence — foundries, IC design houses, OSAT specialists, EDA tool vendors, and semiconductor-equipment / materials suppliers. The list is unranked: sorted by Verified Score, then company name. Inclusion reflects a verified Singapore presence, not endorsement.
The buyer's guide below covers the foundry-vs-OSAT-vs-design distinction, the EDB and IMDA programmes shaping the local ecosystem, and the supply-chain questions critical for the post-CHIPS-Act sector.
How to choose a semiconductor partner in Singapore
Understand the value-chain segment you actually need. Foundries (GlobalFoundries, UMC Singapore, Vanguard) manufacture wafers. OSAT firms (UTAC, ASE, Amkor) handle assembly, packaging, and test. IC design houses do logic design and IP. EDA vendors (Synopsys, Cadence, Siemens EDA / Mentor) provide tooling. Equipment / materials vendors supply the fab itself. A buyer for one segment doesn't help with another — be precise about scope.
Process node and capability fit. Singapore foundries are strong on mature nodes (22nm-180nm), specialty processes (BCDMOS, eFlash, SiGe BiCMOS), and high-mix / high-reliability flows (automotive, industrial, IoT). For leading-edge nodes (sub-7nm), the work is in Taiwan or Korea — not Singapore. Match your product roadmap to the right geographic capability.
Capacity allocation and the post-2022 supply environment. Foundry capacity allocations are still tighter than pre-2022. Lead times of 26-52 weeks for some flows remain common. Demand a NCNR (non-cancelable, non-returnable) commitment with capacity guarantee in writing, plus a clear escalation path if demand spikes.
EDB and IMDA programmes worth knowing. The EDB's Singapore Semiconductor Industry Association (SSIA) and the national Semiconductor Talent Acceleration Pathway are key for talent. IMDA's Singapore Together initiatives and the Research, Innovation and Enterprise (RIE) plan fund R&D and pilot manufacturing. Vendors active in these programmes typically have stronger talent pipelines.
Quality systems and compliance. Automotive customers require IATF 16949. Aerospace/defence: AS9100. Medical: ISO 13485. Industrial: ISO 9001. Singapore vendors at the leading edge will also have IEC 62443 for cyber-physical security in the fab. Demand the actual certificate scope — "ISO 9001 certified" doesn't always cover the specific line you'll buy from.
