The Department of Commerce, specifically the National Institute of Standards and Technology (NIST), is issuing a Combined Sources Sought Notice and Notice of Intent to Sole Source for reference materials related to Total-Reflection X-ray Fluorescence (TXRF). NIST aims to develop new Standard Reference Materials (SRMs) crucial for semiconductor manufacturing, specifically seeking TXRF reference materials containing trace amounts of Ni and Zn on silicon substrates, high-dose shallow boron implants in silicon, and hydrogen concentrations in various silicon compounds. This initiative is part of the CHIPS program, emphasizing the importance of these materials in ensuring quality and consistency in semiconductor production. Interested vendors should submit their capabilities, product specifications, and customer references to Forest Crumpler at forest.crumpler@nist.gov, as responses will inform NIST's market research and potential sole source contract with Cerium Laboratories LLC.
