Recently expanded in 2020 to enable additional capacity and Cu back end of line, our headquarters boasts a rich heritage of technology development and quality volume manufacturing.
Through a partnership with Osceola County, Florida, SkyWater is now the sole operator of the state-of-the-art Center for Neovation where we are onshoring the next generation of advanced packaging.
