Harnessing EUV capabilities for non-destructive metrology

EUV Scatterometry

Ongoing
To measure and inspect the smallest printed features on an IC chip, researchers and manufacturers use a combination of electron scanning modalities (i.e., transmission electron and scanning electron microscopies) and an optical method, scatterometry. Industrially, the most common modality for
Zone Plate Schematic

EUV Zone Plates for Compact Solar Radiometer

Ongoing
A zone plate is an optical element used to separate and focus individual wavelengths of light. The zone plate consists of small circular rings that are opaque to the light separated by gaps, which are transparent. The incident light diffracts from the zone plate at an angle that depends on the
microfluidic chip

Evaluating Measurement Quality of Microfluidic Cell-based Assays

Completed
Impact and Customers Our work establishes metrics for measurement quality and reproducibility for cell-based assays within microfluidic devices. Many novel microfluidic devices are being created that permit new measurements or enable new biological functions to be tested; however, characterizations

Evaluation of 2D and WBG Material Quality Toward Device Reliability

Ongoing
Two-dimensional (2D) and wide band gap (WBG) materials are some of the latest materials classes having the potential to be transformative because of their high carrier mobilities, tunable bandgap, and atomic-scale film thicknesses. Unexpected degradation and failure in device performance is often
Organic light emitting diode, light output is modulated through magnetic control of exciton states

Exciton and Charge Transport Dynamics in Organic Semiconductors

Ongoing
Our approach toward establishing connections between the application space and physical phenomena includes developing electrical/optical devices and measurements that can be used for physical measurement, physical measurements that can be applied to real devices, and device design that can be tuned

Experimental Evaluation of Large-Scale Parallel Measurement Systems

Ongoing
DESCRIPTION: An archetype among biological experiments is gene-by-gene determination of the expression difference between two groups of biological units. For each gene, the experiment yields a data set consisting of one or more expression values for each unit. Gene to gene, these data sets can be

Expert Working Group on Human Factors in Forensic DNA Interpretation

Completed
Forensic DNA interpretation is widely regarded as a critical tool in modern criminal investigations, often seen as the gold standard of forensic evidence due to its potential to help link individuals to crime scenes. The process begins with the collection and preservation of DNA samples—from blood

Explainable Artificial Intelligence Based Modeling Applied to OMICS Problems

Ongoing
The goal of the project is to produce billions of certified values from multiple measurement methods with well-characterized uncertainty in the “’omics” field (genomics, proteomics, transcriptomics). These values are prepared by a joint effort between human experts and trained AI based models for

Extended Cell Testing

Ongoing
The Middle Class Tax Relief and Job Creation Act of 2012 (H.R. 3630) appropriated $7 billion for the establishment of a nationwide interoperable public safety broadband network under FirstNet, an independent authority in the National Telecommunications and Information Administration (NTIA). FirstNet

Extended Digital Thread

Ongoing
OBJECTIVE: To deliver standards, methods, and tools that improve smart manufacturing efficiency, agility, and reliability, by increasing the quality of information representations across more of the product lifecycle, including design, production, and use of resulting products. WHAT IS THE TECHNICAL
ERCC

External RNA Controls Consortium

Completed
While early gene expression measurements with DNA microarrays were groundbreaking in their ability to reveal biological activity, the results were irreconcilable and irreproducible. Industry leaders approached the National Institute of Standards and Technology (NIST) in 2003 for help with addressing

Extreme Atom Probe Tomography

Ongoing
Sub-nanometer-resolved 3-D chemical mapping of any atom in any solid continues to be an imperative goal of materials research. If reduced to practice, it would have profound scientific, engineering, and economic impacts on U.S. industries collectively worth hundreds of billions of dollars. Such

Extreme Ultraviolet Detector Calibration Service

Ongoing
The National Institute of Standards and Technology (NIST) has a wide variety of programs for the calibration of instruments and components for space-based research in the extreme ultraviolet (EUV). Many of these programs have been in existence since the 1960s, and have provided calibration support
Reflectance of two materials

Extreme ultraviolet optical constants

Ongoing
Measurements of EUV optical constants are often made by measuring the absorption or near-normal-incidence reflectivity, then performing transforms to obtain both the real and imaginary parts of the index. These sorts of measurements have considerable uncertainty because they require knowledge of
A high-finesse Fabry-Perot interferometer

Fabry-Perot Displacement Interferometry

Ongoing
Fabry-Perot interferometry has the highest resolution of any displacement sensor, below one picometer, and yet may be used to measure displacements of many centimeters. Equally important, it enables a natural and direct link to the SI unit of length, defined in terms of the speed of light. We are

Face Challenges

Ongoing
Introduction In cooperation with IARPA, NIST is currently running three challenges related to processing of unconstrained in-the-wild face images. These are intended to drive research and development into face detection, verification, identification, and identity clustering. A secondary goal is to

Face and Ocular Challenge Series (FOCS)

Completed
Overview The goal of the Face and Ocular Challenge Series (FOCS) is to engage the research community to develop robust face and ocular recognition algorithms along a broad front. Currently the FOCS consists of three tracks: the Good, the Bad, and the Ugly (GBU); Video; and Ocular. These

Face Projects

Ongoing
Face Technology Evaluations - FRTE/FATE To bring clarity to our testing scope and goals, what was formerly known as FRVT has been rebranded and split into FRTE (Face Recognition Technology Evaluation) and FATE (Face Analysis Technology Evaluation). Tracks that involve the processing and analysis of

Face Recognition Grand Challenge (FRGC)
