NIST seeks information from commercial vendors capable of supplying a new, benchtop environmental test chamber for stressing semiconductor devices with rapid extreme temperature cycles. The chamber must meet detailed technical specifications, including cooling to -68°C and heating to 180°C, and accommodate a 200mm wafer. The system will be installed and operated at Building 220 in Gaithersburg, MD. Vendors must demonstrate prior experience supplying and installing similar systems and provide personnel who can pass government background checks for on-site work. This is a market research request and does not constitute a formal solicitation or commitment to award a contract.
