SPIL Breaks Ground on New Douliu Fab, Betting Billions on AI Advanced Packaging
Nashnova编辑部
ASE-controlled SPIL broke ground on August 11 on a new Douliu fab investing ~NT$100 billion ($3.1 billion) in CoWoS advanced packaging, targeting first production in 2028 — the group's largest single-fab bet on AI packaging to date.
What will this fab actually do?
The Douliu fab covers roughly six hectares in the Yunlin Technology Industrial Park. Its core mission: bring up CoWoS advanced packaging — a process that tiles multiple chips side by side on a single substrate, essential for high-compute AI processors.
Phase one targets 2028 production. It will operate in tandem with the Huwei fab, which began volume production in September 2025. This means → SPIL is building a twin-fab AI packaging cluster in central Taiwan.
Vice chairman Steven Chang said SPIL does not rule out further investment in Yunlin if land and infrastructure allow, to meet demand from top-tier clients.
Where is the money coming from?
SPIL's board recently approved a cash capital increase: 809.7 million new shares at NT$20 per share, raising roughly NT$16.19 billion.
ASE Holdings will subscribe to all new shares, funded by an overseas unsecured convertible bond issuance. In plain terms = the parent borrows abroad, injects the cash into SPIL, and the single-shareholder structure stays unchanged.
This reflects ASE's conviction that AI packaging demand is certain enough to lever up its own credit to fund a subsidiary's expansion.
How big is SPIL's island-wide buildout?
Over the past two years, SPIL has been building or expanding fabs in Taichung, Changhua, Yunlin, Hsinchu, and Tainan. Total investment across Taiwan has reached roughly NT$200 billion, adding more than 8,000 employees.
At full capacity the Douliu fab is expected to create over 2,200 jobs; about 1,300 positions come online with phase one in 2028.
This means → SPIL's expansion is not a single-site bet. It is a multi-city capacity web across central and southern Taiwan, built to capture the 2026–2028 AI demand surge.
Why does the 2028 timeline matter so much?
Steven Chang was explicit: 2026 to 2028 is the critical window for rapid AI demand growth, and SPIL will keep expanding through 2028.
Whether Douliu can bring CoWoS to volume on schedule is the make-or-break milestone for SPIL's AI packaging revenue in that window.
Put simply = a fab this size only pays off if it catches the AI-chip demand wave on time — 2028 is a hard deadline, not a target.
