Chuck Stone

VP, Manufacturing Engineering

Chuck Stone has been vice president of manufacturing engineering since joining Enovix in 2016. He is responsible for scaling production of the Enovix 3D Silicon Lithium-ion Rechargeable Battery for commercialization.

Prior to joining Enovix, Chuck was vice president of manufacturing engineering at SunPower. During his 12 years with SunPower, he led the transfer of a prototype solar cell from research and development to high-volume, low-cost production. He oversaw process and equipment engineering teams that ramped production of three SunPower fabrication facilities, with a combined capacity of more than 1-million solar cells per day. A key component of the high-volume ramp was reducing the cost of SunPower’s world-record, high-efficiency solar cell by a factor of 10 through advanced equipment and process design, lean supply-chain management and improved factory performance.

Prior to joining SunPower, Chuck held the position of senior engineering manager at Cypress Semiconductor. He worked 17 years at Cypress in semiconductor process, device and integration engineering, leading products from research and development to high-volume production. Previously, Chuck was director of manufacturing at EM Microelectronics in Neuchatel, Switzerland, and he held engineering positions with three other semiconductor companies—Silicon Light Machines, National Semiconductor and Mostek.

Chuck studied materials science and engineering at the University of Utah and physics at the University of Texas.
