The MOS21 wafer fabrication plant was Haydon’s first large-scale advanced technology project—and the one that sparked our long-standing passion for building mission-critical facilities, including data centers. At the time, Haydon was a 35-person operation, but we earned the trust of the fab manager based on our ability to stay flexible, deliver with urgency, and manage high-stakes complexity.
The project included a 110,000 SF semiconductor manufacturing facility and a 4,000 SF Class 10 clean room. Subsequent phases added a 21,000 SF central plant, 6,200 SF liquid and gas storage and distribution facility, 15,700 SF support building, and two 24,100 SF Class 10 clean rooms—one as new construction and one as a technology conversion. Even as scope evolved, including a mid-construction change in wafer size, the team maintained schedule and cost control.
This project set the tone for Haydon’s commitment to technical excellence and responsiveness—qualities that continue to define our approach to data center and advanced manufacturing work today.
