Beyond Chipmaking: US Announces Up to $389 Million for Semiconductor Innovation in AI Power Delivery, Fusion Energy, and Critical Materials

The US Department of Commerce announced, that it had signed letters of intent with four companies for up to $389 million in research and development awards under the CHIPS and Science Act.

This funding round addresses a number of interrelated needs of the semiconductor ecosystem, such as effective power conversion, specialised electronics for fusion systems, compact power delivery for advanced computing, and high-purity materials used in semiconductor manufacturing, in contrast to initiatives primarily focused on expanding conventional chip fabrication.

Secretary of Commerce Howard Lutnick stated, “The Trump Administration is accelerating American semiconductor innovation to enhance our domestic energy and power resources.” “These investments secure vital supply chains, increase domestic research, and generate well-paying American jobs.”

The proposed awards reflect a wider industrial challenge. As computing infrastructure becomes more power-intensive and energy technologies grow more sophisticated, semiconductor innovation increasingly depends on components and materials that can operate reliably under demanding electrical, thermal, and environmental conditions.

The four companies selected for the proposed awards are Helion, Commonwealth Fusion Systems, Vertical Semiconductor, and Sibelco.

Four Companies, Four Technology Priorities

1. Helion: Up to $175 Million for Fusion-Related Power Semiconductors

Helion is set to receive the largest proposed award, with funding of up to $175 million to develop and establish domestic capabilities in high-voltage power semiconductors and advanced energy power modules.

The technologies are intended for high-peak-current pulsed-power applications in fusion power generation. These semiconductor systems will support the operation of magnets used in Helion’s fusion generators, helping power, control, and recover energy from the systems.

The investment places power electronics at the intersection of semiconductor manufacturing and emerging energy technology.

For the broader industry, it highlights how specialised semiconductor devices can become critical components in applications extending well beyond conventional consumer electronics and computing.

2. Commonwealth Fusion Systems: Up to $85 Million for Advanced Fusion Electronics

Commonwealth Fusion Systems is slated to receive up to $85 million for research into semiconductor technologies supporting radio-frequency plasma heating, power electronics, embedded electronics for fusion diagnostics, and radiation-hardened systems.

Fusion facilities require sophisticated electronic infrastructure capable of supporting complex energy systems and operating under demanding conditions.

Developing these technologies domestically could help expand the specialised semiconductor capabilities needed for future fusion installations while creating opportunities for collaboration across the electronics, materials, and energy industries.

3. Vertical Semiconductor: Up to $73 Million for Vertical Gallium Nitride Technology

Vertical Semiconductor’s proposed award of up to $73 million will support the development of vertical gallium nitride (GaN) power semiconductors.

GaN is attracting attention in power electronics because of its potential to support efficient, high-frequency switching and compact power-conversion systems. These characteristics can be valuable in applications where power density, thermal management, and energy efficiency are important.

The company’s programme aims to advance more efficient power delivery for advanced computing and demonstrate the technology for a proposed 2.5-megawatt AI data-centre rack.

As AI infrastructure expands, the challenge is no longer limited to providing sufficient computing capacity. Delivering electricity efficiently to increasingly dense computing systems is also becoming a critical engineering priority.

4. Sibelco: Up to $56 Million for Ultra-High-Purity Quartz

Sibelco’s proposed award of up to $56 million will support advanced purification and finishing technologies for ultra-high-purity quartz.

This material is used in crystal-growth crucibles, processing glassware, and other equipment throughout the semiconductor manufacturing value chain.

Material purity is essential in semiconductor production, where contamination can compromise manufacturing processes and affect yield and reliability.

Strengthening domestic capabilities in high-purity quartz processing could therefore support an important part of the semiconductor supply chain that receives less public attention than chip design or fabrication, but remains essential to manufacturing operations.

Supply-Chain Resilience Extends Beyond Finished Chips

The inclusion of ultra-high-purity quartz in this funding round is another significant element.

• Semiconductor supply chains rely on an extensive network of materials, processing equipment, and specialised components. Disruptions or capacity constraints in these upstream segments can affect manufacturers even when chip fabrication capacity is available.
• Developing domestic purification capabilities could help strengthen access to a material used in important semiconductor manufacturing processes.
• For materials suppliers and semiconductor equipment companies, this creates a broader strategic consideration: competitiveness increasingly depends on the availability and quality of critical inputs, not simply on the ability to manufacture finished semiconductor devices.
• The initiative also illustrates how semiconductor policy can influence adjacent industries, including advanced materials, industrial processing, energy technology, and equipment development.

The proposed awards form part of the federal government’s wider semiconductor research and development effort under the CHIPS and Science Act.

A notable feature is the planned financial arrangement. As a condition of the awards, the US Department of Commerce will receive minority, non-controlling, and non-voting equity stakes in each company.

This structure gives the government a financial interest in the recipients without providing controlling voting rights through those stakes.

Importantly, the announcement concerns letters of intent for proposed awards. The amounts should therefore be understood as funding ceilings associated with the announced arrangements, rather than evidence that the full amounts have already been disbursed.

The announcement comes as governments and manufacturers consider how to build semiconductor ecosystems that can support increasingly complex computing and energy requirements.

For semiconductor developers, the emerging priorities include power efficiency, reliability, thermal performance, and the integration of advanced electronic systems. For materials suppliers, purity, processing capabilities, and supply-chain continuity remain central concerns.

The four proposed awards address different parts of this picture, but their shared objective is to advance technologies that support critical infrastructure and strengthen domestic research and manufacturing capabilities.

Commercial outcomes will ultimately depend on whether the funded research can translate into reliable products, scalable manufacturing processes, and competitive technologies. Progress in these areas will also depend on technical validation, investment, customer adoption, and the ability to move from research to deployment.

The larger message is clear: semiconductor competitiveness is becoming a broader systems challenge. Beyond developing more capable chips, the industry must also improve how power is delivered, how specialised electronics operate in demanding environments, and how essential manufacturing materials are produced.

The companies and technologies supported by this initiative will be worth watching as the United States continues to develop its semiconductor and advanced-energy capabilities.
