Investing and Partnering in North Carolina to Build a Talent Pipeline

Wolfspeed is partnering with North Carolina Agricultural and Technical State University (N.C. A&T) to establish comprehensive education and training curricula and cutting-edge research and innovation programs. In 2020, Wolfspeed committed $4 million over five years to the university, at the time the single largest donation in the university’s history, to create the Wolfspeed Endowed Scholars Program. The two entities aim to create opportunities for undergraduate and graduate credentials in Silicon Carbide semiconductor manufacturing as well as training and career advancement programs for existing semiconductor manufacturing workers.

The Siler City campus will also sit within 60 miles of North Carolina’s prestigious academies, allowing us to create relationships with future high-tech professionals and innovators. Combining Wolfspeed’s 35-year history of research and development in North Carolina with the high-quality talent in the state, we will establish a rich talent pipeline for the next generation in our local community.

A Focus on Sustainability

Sustainability isn’t just something we do; it’s woven into the fabric of our company and core values. From the products we make, to the we way make them and how we interact with our communities, sustainability is into all facets of how we operate. Expanding is no exception. The John Palmour Manufacturing Center for Silicon Carbide will strive to have the following features when fully built.

Being LEED certified for building efficiency
Sourcing electricity from carbon-free or low-carbon sources
Deploying water recycle processes
Electric vehicle charging stations on campus

Giving Back & Closing the Opportunity Gap

We believe every individual should have a roof over their heads, food to eat and an opportunity to excel. Investing in and giving back to the communities where we live and work is part of who we are as a team, and we are excited to extend these investments to Chatham County. Included in our 2022 sustainability goals, Wolfspeed has the ambition to close the opportunity gap by providing more opportunities for STEM education, at all levels, to people in need, particularly in underserved communities.
