Inside a semiconductor fabrication plant, silicon wafers move through hundreds of tightly controlled processes before becoming the tiny chips used in cars, smartphones, data centres, medical equipment and defence systems. A single speck of dust can damage a wafer, which is why these facilities contain advanced cleanrooms, precision tools and highly trained engineers.
New York has developed one of America’s most important semiconductor ecosystems. Malta, Albany, Marcy, East Fishkill and Clay now support chip manufacturing, power-semiconductor production, advanced research and major future investment. Based on active operations, technology importance and long-term impact, here are five leading semiconductor companies in New York in 2026.
1. GlobalFoundries
GlobalFoundries is the most established large-scale semiconductor manufacturer headquartered in New York. Its Malta campus serves as both the company’s global headquarters and one of its principal manufacturing facilities.
The highly automated 300-millimetre fab produces chips using technologies including FinFET, FD-SOI, RF-SOI and silicon photonics. These chips support automotive systems, communications infrastructure, artificial intelligence, aerospace, defence and industrial applications. The company reports approximately 2,500 employees and annual capacity equivalent to around 400,000 300-millimetre wafers at the Malta site.
GlobalFoundries is also creating a New York Advanced Packaging and Photonics Center at the campus. The company has announced broader investment plans covering semiconductor manufacturing and advanced packaging in New York and Vermont.
Why GlobalFoundries is included: Its operational fab, New York headquarters, substantial workforce and specialised manufacturing technologies make it the state’s leading semiconductor company.

2. Micron Technology
Micron Technology is one of the world’s major memory-chip manufacturers. Its products include DRAM, NAND flash and high-bandwidth memory used in computers, smartphones, vehicles, storage systems and artificial-intelligence infrastructure.
Micron broke ground on its planned semiconductor megafab in Clay, near Syracuse, in January 2026. The company plans to develop multiple fabrication facilities at the site, with investment potentially reaching $100 billion over approximately two decades. However, the Clay complex is still under construction and is not producing chips in 2026.
The project is designed to restore advanced memory manufacturing capacity in the United States. New infrastructure, workforce programmes and semiconductor training partnerships are being developed around the Central New York site.
Why Micron Technology is included: Although production has not started, the scale of its Clay megafab makes Micron one of the most important companies shaping New York’s semiconductor future.

3. Wolfspeed
Wolfspeed operates the Mohawk Valley Fab in Marcy, near Utica. Instead of focusing on conventional silicon chips, the company specialises in silicon-carbide semiconductors.
Silicon carbide can operate efficiently under high voltage, high temperature and demanding power conditions. Wolfspeed’s products are used in electric vehicles, renewable-energy systems, industrial motor drives, fast-charging equipment and data-centre power supplies. The company describes itself as a major pure-play provider of silicon-carbide substrates and power-semiconductor products.
Wolfspeed completed a financial restructuring and exited Chapter 11 bankruptcy in September 2025 after reducing a large portion of its debt. Its official 2026 location directory continues to list Marcy as an active US location.
Why Wolfspeed is included: Its Mohawk Valley facility gives New York an important position in the growing market for energy-efficient silicon-carbide power devices.

4. onsemi
onsemi operates a 300-millimetre semiconductor manufacturing facility in East Fishkill. The site was formerly associated with IBM and GlobalFoundries before onsemi completed its acquisition of the facility.
The company produces intelligent power and sensing technologies for automotive and industrial customers. Its wider portfolio includes power-management chips, sensors, MOSFETs, silicon-carbide products, connectivity devices and integrated circuits used in electric vehicles, factory automation, energy infrastructure and advanced driver-assistance systems.
onsemi’s official location directory identifies East Fishkill as one of its current North American manufacturing facilities. The fab strengthens the company’s ability to increase 300-millimetre wafer production and improve manufacturing efficiency.
Why onsemi is included: Its operational East Fishkill fab and concentration on automotive, industrial and power-management semiconductors make it a major New York chip manufacturer.

5. IBM Research
IBM is no longer a large commercial semiconductor foundry, but it remains one of New York’s most important chip-research companies. Its semiconductor teams work at the Albany NanoTech Complex and the Thomas J. Watson Research Center in Yorktown Heights.
IBM Research focuses on transistor architecture, advanced logic, chiplets, semiconductor packaging, artificial-intelligence hardware and intelligent manufacturing. Its work includes sub-2-nanometre technologies, nanosheet transistors, co-packaged optics and experimental AI chips.
In June 2026, IBM announced a sub-1-nanometre research-chip architecture developed through its New York semiconductor research operation. The technology remains at the research stage rather than being a mass-produced commercial processor.
Why IBM Research is included: Its Albany research teams continue to develop semiconductor technologies that may influence future manufacturing processes across the global chip industry.

What Makes New York Important for Semiconductors?
New York combines operational fabs with advanced research, universities, workforce programmes and government-supported facilities. GlobalFoundries, Wolfspeed and onsemi already manufacture chips in the state, while IBM develops future semiconductor processes and Micron is constructing a major memory-manufacturing complex.
The Albany NanoTech Complex further strengthens this ecosystem by allowing chipmakers, equipment companies, universities and researchers to collaborate on advanced lithography, materials and packaging technologies.
Frequently Asked Questions
Q: Which is the largest active semiconductor manufacturer in New York?
A: GlobalFoundries currently has the most significant established manufacturing operation in the state through its Malta campus.
Q: Is Micron already producing chips in New York?
A: No. Micron’s Clay megafab is under development in 2026. Commercial chip production is expected later, after construction and equipment installation are completed.
Q: What type of chips does Wolfspeed manufacture?
A: Wolfspeed manufactures silicon-carbide power-semiconductor devices. They are used where high efficiency, voltage tolerance and temperature performance are important.
Q: Does IBM still manufacture commercial chips?
A: IBM mainly concentrates on semiconductor research, architecture and technology development. Commercial manufacturing of technologies developed by IBM is generally handled through manufacturing partners.
