Understanding the Vital Role of CHIPS Act Backing for GlobalFoundries
The announcement of a preliminary memorandum to allocate approximately $1.5 billion in direct funding under the CHIPS and Science Act to GlobalFoundries (GF) has stirred significant interest and discussion. This move underscores a strategic investment in critical domestic capabilities revolving around mixed signal and analog technology, which form an integral part of the semiconductor industry. While a substantial portion of this funding is earmarked for the expansion of GF’s facilities in Malta, NY, it’s crucial to highlight the importance of the investment in its Fab 9 in Essex Junction (Burlington), Vermont.
The Significance of Fab 9 Revitalization
Fab 9 holds historical significance, having been acquired from IBM in 2015. Once IBM’s premier fab, it witnessed a shift in leading-edge investments to East Fishkill, NY, which was later acquired by GF. Despite its niche processes, including gallium nitride (GaN) on silicon and silicon germanium (SiGe), Fab 9 remained relatively understated until recent developments.
Gallium Nitride (GaN) – Unveiling Revolutionary Potential
GaN, a wide bandgap semiconductor, offers revolutionary potential in various applications owing to its unique properties. Unlike conventional silicon chips, GaN-based devices can handle higher voltages and operate at higher temperatures, making them ideal for power electronics and electric vehicle charging systems. Additionally, GaN’s rapid electron mobility makes it invaluable for radio components in smartphones and emerging technologies like 5G and 6G.

Overcoming Technical Challenges
However, the production of GaN devices presents technical challenges due to its compound semiconductor nature. Integrating GaN with silicon substrates, though cost-effective, requires addressing issues of lattice and thermal mismatch, demanding specialized knowledge and sophisticated manufacturing processes.
Silicon Germanium (SiGe) – Enabling High-Frequency Devices
SiGe, with its higher electron mobility compared to silicon, excels in high-frequency applications, making it indispensable for telecommunications devices. GF’s expertise in SiGe processes, particularly in producing RF power amplifiers, positions it as a key player in the telecommunications industry.
Government Support and Strategic Partnerships
The government’s decision to fund the revitalization of Fab 9 underscores the strategic importance of securing domestic semiconductor capabilities. Furthermore, partnerships with key customers like Raytheon, along with GF’s participation in the DoD Trusted Foundry Program, highlight the critical role played by GF’s facilities in New York and Vermont.
Investing in Future Resilience
Investing in semiconductor capabilities at this juncture is crucial, considering the United States’ leading position in the field. By bolstering facilities like Fab 9, the nation can maintain its technological edge and ensure resilience in the face of evolving challenges.
In conclusion, the support provided under the CHIPS Act for GlobalFoundries signifies a proactive approach to strengthening key domestic capabilities in the semiconductor industry. This investment not only revitalizes critical facilities but also ensures the nation’s resilience and leadership in semiconductor innovation.
