The Department of Commerce, specifically the National Institute of Standards and Technology (NIST), has issued a Sources Sought Notice to identify vendors capable of providing two Highly Accelerated Stress Test (HAST) chambers. These chambers are essential for accelerating moisture-induced failures in semiconductor devices, which are critical for defect characterization, failure analysis, and metrology development under the CHIPS Metrology program. The procurement seeks chambers with specific technical requirements, including multi-mode humidity control, temperature and pressure ranges, and compliance with industry standards. Interested vendors should submit their capabilities, including technical specifications and pricing, to Forest Crumpler at forest.crumpler@nist.gov. This notice is for market research purposes only and does not constitute a solicitation or commitment to award a contract.
