• Title: Sources Sought Notice for Coincident gamma ray detection system, Scintillation Detector
  BACKGROUND
  The semiconductor supply chain is global, specialized, and interconnected. Chipmakers do business with thousands of individual suppliers that provide the highly complex materials and tools used to produce semiconductors. To address the lack of full visibility into the semiconductors markets supply chain and R&D ecosystem gaps NIST will conduct the measurement science, or metrology, critical to the development of new materials, packaging, and production methods in chip manufacturing.
  NIST seeks to procure two scintillation detectors, one for gamma rays, the other for combined neutron/gamma, and their associated photomultiplier tubes. These detectors will be used in the neutron/gamma field generated by a portable neutron generator and the irradiated sample environment. They will produce prompt gamma spectrum using a portable neutron generator-based prompt gamma activation analysis (PGAA) for quantitative elemental determination in semiconductor bulk material. NIST seeks to establish coincidence detection system to minimize background gamma rays for improved signal to noise ratio and enhanced detection limit for critical elements in semiconductor material. In hopes to improve critical elements, especially light elements, such as H, B, N, in semiconductor material either intrinsic or added during manufacturing process can significantly affect the quality of the performance of the end product, in addition to metallic contaminants. PGAA is a unique non-destructive technique for quantitative analysis for these elements. PGAA is traditionally based on neutron beams from a nuclear reactor and therefore is less accessible to laboratory use. The proposed portable neutron generator-based PGAA, while 2 to 3 orders of magnitude lower in thermal neutron flux, can be suitable for elements of high capture cross sections, and through this project, demonstrate the potent...
