Applied Materials has opened its EPIC Center in Sunnyvale, Calif., a 600,000-square-foot semiconductor R&D building with roughly four acres of cleanroom. The company calls it the world’s largest facility for collaborative chip process and equipment research, and says total investment will grow to about $5 billion as customer projects come online.
The opening was announced Oct. 12, and ConstructConnect reported that the build took more than 6 million construction hours. TSMC, Intel, Samsung Electronics, Micron and SK hynix signed on as founding partners. Broadcom, Advantest, SCREEN, KIOXIA and Besi joined as innovation partners, with five universities on the research side.
How the EPIC Center budget grew
When Applied announced the project in May 2023, it said it would invest “as much as $4 billion.” ENR reported at the time that the plan included 180,000 square feet of cleanroom, about 1,500 construction workers and completion by early 2026, contingent on CHIPS Act incentives. By February 2026, Applied was calling it a $5 billion facility.
Part of that is accounting, not overruns. Applied’s framing is that capital spending rises toward $5 billion over time as partners bring in tools and programs, so the figure includes equipment that hasn’t been installed yet. The company hasn’t broken out what the building and central plant cost against the tool budget. It also hasn’t named a general contractor or cleanroom builder.
The cleanroom number held up. About four acres works out to roughly 174,000 square feet, close to the 180,000 promised in 2023. The schedule held too: the 2023 target was early 2026, and the doors opened in October.
What’s inside the Sunnyvale semiconductor R&D campus
Applied’s EPIC page lists an all-electric central VOC abatement unit and electrified central facilities with no combustion boilers. It says the building is designed to recycle or reuse about 40% of its water.
RMW architecture & interiors developed the site program and master plan for the roughly 67-acre campus, according to the firm. The plan covers the R&D building with its ballroom-style cleanroom, a central utility plant, light lab and office buildings, and parking, phased to grow over the next decade. Later phases add amenity and supplemental research space, so there’s more work coming on this site.
Why chip R&D megaprojects matter for builders
Most semiconductor megaprojects are fabs in places with cheap land and power. This one is an R&D building in the middle of Silicon Valley, and it shows the cleanroom market isn’t only about production. Fabs are still coming: GlobalFoundries is lining up two new Malta fabs backed by up to $21 billion, also without a named builder.
For contractors, the takeaway is that the 2023 numbers mostly held on a cleanroom job of this size. The open question is the next phase on the 67 acres, and whether Applied names who’s building it.
