The Department of Commerce, specifically the National Institute of Standards and Technology (NIST), is conducting market research through a Sources Sought Notice for the procurement of five 220 GHz on-wafer probes to support its CHIPS program. The probes are essential for manufacturing on-wafer standards for S-parameters and power measurements up to 330 GHz, with the goal of providing known permittivity measurements for on-wafer traceability. Interested vendors are encouraged to submit their capabilities and relevant product information to Cielo Ibarra at cielo.ibarra@nist.gov by December 15, 2025, as this notice is for market research purposes and does not constitute a commitment to award a contract.
