Meanwhile, the other state-backed foundry, Intel, wraps up RAMP-C defense test chip program
The US government has signed a letter of intent to provide GlobalFoundries with $300 million in CHIPS Act funding and, at the same time, receive a one percent stake in the company worth roughly $269 million. The money's supposedly not a tit-for-tat, but an investment designed to spur development of silicon photonics networking technologies that the AI industry needs for datacenters. “With today’s compute supply chain investments, the Trump Administration is accelerating America’s innovation engine,” Commerce Secretary Howard Lutnick said in a canned statement. “These strategic investments will enhance our country’s domestic capabilities, create high-paying jobs and keep America at the forefront of the semiconductor industry.” GlobalFoundries’ previously announced Silicon Photonics Co-Packaged Advanced Light Engine (SCALE) is one of the technologies it’s pushing in order to support 400 Gb/s per lane connectivity, which is about the speed at which copper interconnects become problematic for large scale systems.
Both CPO, where optical engines are integrated directly into the compute logic, and NPO, where the optics reside in a module adjacent to the compute, are expected to be big business over the next couple of years. At Computex in Taipei last month, Nvidia CEO Jensen Huang quipped that these technologies would make Marvell Technology the next trillion dollar company.
