Arizona’s semiconductor growth is starting to show up in places beyond the major fab sites. Increasingly, it is appearing in land transactions, rail-served sites and industrial facilities built to support large-scale manufacturing. One of the clearest signals of that shift came in late December, when Sunlit Arizona purchased 40 acres in Casa Grande for a planned hydrofluoric acid manufacturing facility.
Sunlit is the U.S. subsidiary of a Taiwan-based semiconductor chemical supplier that provides specialty materials used in chip fabrication. The company established its first U.S. operation in Metro Phoenix’s Deer Valley area in 2024, supplying chemicals used in advanced manufacturing processes at semiconductor facilities.
The $9.2-million land purchase positions Sunlit to support Arizona’s expanding semiconductor supply chain with a material used throughout chip production. Hydrofluoric acid is a chemical used in multiple stages of wafer processing and, as more fabs come online in the state, suppliers are moving closer to customers to reduce logistics risk and dependence on overseas production.
Auza Ranches LLC sold the land, with Land Advisors Organization representing both buyer and seller. The transaction closed in late December 2025 and reflects what brokers say is a broader recalibration in how industrial users are selecting sites tied to semiconductor manufacturing.
“This transaction reflects what sophisticated industrial users are prioritizing today, which is rail access, speed to execution and the ability to control enough land to grow without constraint,” says Kirk P. McCarville, CCIM, a Pinal County specialist with Land Advisors Organization. He adds that Casa Grande remains one of the few Arizona markets where manufacturers can meet immediate operational needs while planning for long-term expansion.
Sunlit selected Casa Grande based on the market’s industrial fundamentals, rail connectivity, land pricing and cost-of-living considerations for future employees. This Sunlit deal marks the 10th semiconductor-related supplier to establish operations in Casa Grande, a clear demonstration of how Arizona’s chip growth is no longer confined to the City of Phoenix and its immediate suburbs. Smaller cities are starting to feel the pull as suppliers look for space, access and certainty they can no longer find closer to the core.
The economic impact of this sale extends beyond the facility itself because facilities like this tend to reshape more than a single parcel. Chemical manufacturing tied to semiconductor production brings specialized logistics requirements, coordination with utilities and long-term industrial occupancy factors that influence the shape of infrastructure planning and land use.
Drawing sustained interest from manufacturers and suppliers serving both the semiconductor and electric vehicle sectors, Casa Grande is slowly emerging as a secondary hub supporting Arizona’s semiconductor corridor. Located along key transportation corridors and offering rail access that is increasingly hard to secure in denser metro areas, the city has become a practical choice.
The Casa Grande site provides Sunlit room to scale as the chip industry continues to mature in Arizona. At the same time, this deal reflects how semiconductor growth is spreading beyond Arizona’s core metro areas and into cities positioned to support the industry’s next phase.
Recent Semiconductor Investments in Casa Grande
- NRS Logios America facility opening — May 28, 2025: NRS Logios America opened its first U.S. chemical logistics park in Casa Grande, built on a 40-acre site to serve semiconductor and battery materials supply chains. The facility is projected to support logistics, storage and distribution, with expansions planned to include rail infrastructure.
- KPPC Advanced Chemicals groundbreaking — Dec. 22, 2025: KPPC Advanced Chemicals began construction of its Catholic Valley Industrial Park semiconductor chemical campus, a next-generation ultrapure chemical production site. The initial phase is a $120-million investment, with plans to grow to about $500 million over time to supply high-purity materials for fabs that include TSMC, Intel and Micron.
- Chang Chun Arizona groundbreaking — Oct. 20, 2022: Taiwanese chemical supplier Chang Chun Arizona broke ground on its first U.S. manufacturing facility in Casa Grande, a project expected to produce electronic-grade chemicals for chip manufacturing and create more than 200 jobs with a roughly $300 million investment.
