IMEC’s 325GHz chip platform could make 6G deployment affordable

IMEC, the Belgian semiconductor research organization collaborating with over 600 chip industry partners, has unveiled three new manufacturing capabilities on its 300mm RF silicon interposer platform. These advancements significantly reduce the cost and complexity of 6G chip production, bringing next-generation wireless technology closer to widespread commercial deployment.

The enhanced platform now operates with record-low signal loss at frequencies reaching 325GHz, spanning the critical millimetre-wave and sub-terahertz bands essential for 6G networks. This breakthrough addresses one of the biggest barriers to 6G adoption: the high cost of manufacturing chips capable of handling such extreme frequencies. By leveraging silicon-based interposer technology rather than more expensive alternatives like gallium arsenide, IMEC’s approach could make affordable 6G infrastructure a reality for telecom operators.

Lower signal loss at these frequencies means less power is wasted during transmission, which directly improves network efficiency and reduces the need for costly signal boosters. For telecom companies eyeing 6G deployment, this translates into lower capital expenditure and faster return on investment. The platform’s compatibility with existing 300mm wafer fabrication processes also means manufacturers can scale production without retooling their entire facilities.

IMEC’s work aligns with broader industry efforts to standardize 6G technology, expected to launch commercially in the early 2030s. The institute’s latest milestone suggests that cost-effective, high-performance chip solutions are within reach, potentially accelerating the timeline for 6G network rollout worldwide.
