The National Institute of Standards and Technology (NIST) intends to negotiate a sole source contract with Silterra Malaysia Sdn. Bhd. for the procurement of 0.18um CMOS wafers, which are critical for ongoing research and development efforts. NIST requires these wafers to maintain compatibility with previously acquired products that were manufactured to specific proprietary specifications, ensuring the reproducibility of scientific results and supporting a collaborative research agreement with Western Digital Research. The procurement is essential as Silterra is the only manufacturer capable of providing wafers that meet the government's stringent requirements, and the resulting purchase order will be a Firm Fixed Price contract. Interested parties who believe they can meet these requirements are encouraged to submit their capabilities to the designated contacts, Joni L. Laster and Forest Crumpler, via email, as no solicitation package will be issued.
