The work will entail:

NIST’s Engineering Lab (EL) Systems Integration Division, Life Cycle Engineering Group is seeking a researcher in operations research and industrial engineering. We are expanding our research to develop ways of maximizing the value of U.S. microelectronics and semiconductors based on principles of circular economy. 

Microelectronics are valued for their processing capabilities and the materials that they contain.  Operations research is applied to enable value recovery from the perspective of measuring the flow of materials, used in semiconductors, throughout the economy.  We create methods to measure what, when and how much material will become available in the future and viable pathways for reclaiming those materials into the economy. 

By applying advanced forecasting methods to establish and validate circular pathways for microelectronic recovery, the project will deliver science-based techniques that strengthen domestic semiconductor manufacturing capabilities. The results will include a suite of decision support tools (metrics, models, and published research) to improve recovery outcomes, thereby strengthening supply chain resiliency via new material sources, and enabling stakeholders to respond dynamically to material availability challenges in the future.

We seek experienced research candidates with a background in micro and nano engineering, operations and/or supply-chain management, and a Ph.D., M.S. and/or related experience with a record of research in peer-reviewed publications.  US citizenship needed.

Key responsibilities will include but are not limited to:

• Conduct a literature survey including data collection on state-of-the-art of the microchip manufacturing process and chip product value chain.
• Develop a strong understanding of the microchip market including the strengths and limitations of U.S. chip-making.
• Develop high fidelity simulation models (across multiple product life cycles and product value chains) to quantify and characterize the material stocks and flows, and uncertainties and risks associated with domestic chip manufacturing sector.
• Propose and develop quantitative evaluation metrics to effectively maximize microchip value.
• Regularly synthesize results and analyses of findings and disseminate these via NIST program partners, special reports, high-impact journal publications and as presentations at technical conferences.

Qualifications:

Desired skills/technical knowledge include a combination from the following:

• An understanding of micro/nano fabrication processes for chips and first-principle modeling

The work will entail:

In semiconductor manufacturing and metrology, optical techniques are often utilized to assess the
quality of wafers or epitaxially grown layers because local material defects or contamination are
detrimental to device performance. Increasingly, these optical techniques are based on hyperspectral
imaging principles where every pixel of an image contains both the spatial and the spectral information
corresponding to photons arriving from a part of the chip. One very popular optical imaging method is
photoluminescence (PL) imaging where an area of the material is optically excited by a laser, or an LED
and the emitted luminescence photons are intercepted via a detector such as a spectrometer or a
filtered camera.

This research is focused on the development of a standard reference light source that can be used to
calibrate any wide field or scanning imaging system such that every pixel of an image is calibrated to
show the actual photon flux leaving the surface of the semiconductor material or the chip. Furthermore,
this reference light source will produce spectral photon flux maps so that hyperspectral images at
various emitted photon energies are calibrated in an absolute way. We will work on a process to ensure
that the measured defect emission spectra are properly scaled by a NIST calibration specimen such that
one can make a meaningful comparison between different optically detected defects measured on
readily available commercial devices. Furthermore, the radiative efficiency of the material will be
determined, which will directly correlate with the material quality and allows the manufacturer to reject
high-impurity, defective wafers during inline monitoring.

Key responsibilities will include but are not limited to:

• Perform uniformity mapping of standard light sources using programmable translational scanning stages.
• Perform angular measurements of light leaving various light sources using an in-house programmable robotic arm.
• Calculate a spectral calibration factor and develop a mathematical approach to apply it to every pixel of a hyperspectral luminescence image.
• Test the developed calibration factor on a few semiconductor wafers such as on GaAs or GaN chips.
• Develop an uncertainty budget for the measurement and analysis protocol.

Qualifications:

• Ph. D. degree in Physics, Computer Science, Electrical or Mechanical Engineering, or a related field.
• 2 years of relevant experience, including graduate research work.
• Familiarity with data analysis techniques and mathematical computations using programming tools such as Mathematica, Python or MATLAB.
• A strong desire to collaborate with other researchers and be involved on various related projects.
• Strong oral and written communication skills.

The PREP program requires staff from a wide range of backgrounds to work on scientific research in many areas.

The work will entail:

Commercial phase change materials (PCMs) in the US and EU markets are incorporated in macro- and micro-encapsulations for latent heat storage in building energy applications. The thermal conductivity and the specific heat capacity of these PCM products, which are usually reported in the specification’s datasheet and are measured by a Heat Flow Meter (HFM), are the main thermal data used for installation guidance and energy saving calculations. However, these measurements exhibit non-linear behaviors with temperature due to contributions from the encapsulation materials and other factors. Therefore, the thermal behavior of encapsulated PCMs masks the thermal properties of the actual PCM and its phase change properties. Furthermore, the measurement by an HFM is fundamentally a relative measurement being heavily correlated with the calibration of internal heat flux transducers using a reference material.

This work aims to establish the groundwork needed to develop a reference material for validating the specific heat capacity values, as well as thermal conductivity of macro-encapsulated PCMs. The research focus is to ultimately provide a new measurement service by developing a PCM reference material with reliable thermal properties and a well-defined phase-temperature relationship.

Key responsibilities will include but are not limited to:

• Simulating thermal distributions on empty and PCM filled – encapsulation panels between heating and cooling sources.
• Determining thermal conductivity and heat capacity values of the PCM encapsulation panels using computational methods.
• Analyzing PCM melting and solidification process in the encapsulations using computational methods.
• Presenting results at internal meetings, and occasional meetings with external stakeholders.
• Ensuring that results, protocols, software, and documentation have been archived.

Qualifications:

• A minimum master’s degree in computer science, Engineering, Manufacturing, or a related field.
• A minimum of 2 years of relevant experience is preferred.
• Familiarity with PCM and thermal simulations is a big plus.
• Ability to work with a commercial finite element software (experience with COMSOL is preferred but not required).
• Ability to develop an analytical model needed to analyze data.
• Strong oral and written communication skills.
