MANY MINDEDSandboxAQ advances PFAS-free semiconductor materials
SandboxAQ, a Silicon Valley startup, received $500 million from the CHIPS and Science Act in June 2026 to develop PFAS-free alternatives for semiconductor manufacturing. The company uses large quantitative models to identify candidate materials across four categories—catalysts, rare-earth-free magnets, battery systems, and PFAS-free chemicals—having conducted 1 million CPU cloud simulations of PFAS molecules. While SandboxAQ states its research shows promise through iterative testing and targets candidate material identification within 2-4 years, this timeline represents lab-stage work, not full industry adoption. The Semiconductor Industry Association estimates PFAS-free alternatives could take 3-25 years to implement, and PFAS remain currently used in semiconductor processes like photolithography. State bans on PFAS exist but exempt semiconductor manufacturing due to critical industry needs. This work addresses environmental health risks from PFAS pollution in the semiconductor sector, a key concern for SECURITY and THE COMMONS. The source provides limited detail on implementation barriers and long-term adoption pathways.
