Applied Materials Inc., which supplies equipment for semiconductor chip manufacturers, has announced plans to build a research and development center in California that could, contingent on receiving Chips and Science Act incentives, be the largest facility of its kind in the world.

The so-called Equipment and Process Innovation and Commercialization, or EPIC, Center, would include 180,000 sq ft of cleanroom. Applied Materials says it plans to invest as much as $4 billion in the facility, which would be built at its Silicon Valley campus in Sunnyvale, Calif.
