BACKGROUND

The National Institute of Standards and Technology (NIST) is conducting market research to identify alternative sources that (a) are capable of meeting NIST’s minimum requirements for the following commercial products and commercial services and (b) would be interested in competing for that requirement:

The Precision Imaging Facility at the National Institute of Standards and Technology (NIST) is involved in the characterization of metals, semiconductors, and insulators in support of multiple projects.  Materials characterization allows NIST scientists to make direct correlations between material processing, (nano)structure, and resulting properties.  This work involves the correlation of processing, structure, and properties of semiconductor material devices using three-dimensional X-ray computed tomography (XCT).  Consistent with NIST’s mission to develop measurement science, a particular research focus is to evaluate the sources of systematic and statistical error that limit the efficacy of XCT techniques, to devise strategies to mitigate these uncertainties, and to develop metrics that quantify the results.

The NIST PIF owns and performs research using a Zeiss Versa XRM 500 microscope system. The system is now over ten years old and is no longer eligible for technical service support from the manufacturer or any third parties. NIST now requires a new XCT microscope for micro-scale three-dimensional imaging of semiconductor materials and devices. The new microscope must meet the requirements detailed below and the ability to produce data which is compatible with data previously produced by NIST’s current Zeiss Versa XRM 500 microscope system.
