Union City, California, has opened the first US facility dedicated to advanced semiconductor packaging, marking a milestone in the global artificial intelligence chip race. The facility is operated by Japanese chemical company Resonac and is expected to bring cutting-edge work to the Bay Area. The decision to locate the center in Silicon Valley was driven by the region's pace and culture, compared to Japan's slower pace. The work inside the facility focuses on how chips are assembled, a segment of the supply chain the US has been seeking to strengthen as demand for artificial intelligence technology increases. The opening of the facility is seen as a milestone for industry and a significant step forward in the development of advanced semiconductors.
