Postdoctoral Fellow

General Description

PREP Research Associate

CHIPS Funded Project

This position is part of the National Institute of Standards (NIST) Professional Research Experience (PREP) program. NIST recognizes that its research staff may wish to collaborate with researchers at academic institutions on specific projects of mutual interest, and thus requires that such institutions be the recipient of a PREP award. The PREP program requires staff from a wide range of backgrounds to work on scientific research in many areas. Employees in this position will perform technical work that underpins the scientific research of the collaboration.

Research Title:

Modeling and Mechanical Testing for Heterogenous Structures of Advanced Semiconductor Packaging

The work will entail:

The Infrastructure Materials Group at the National Institute of Standards and Technology seeks a researcher with extensive expertise in finite element analysis and knowledge of one or more of the following technical areas: instrumented mechanical testing, adhesion testing, polymer degradation characterization, and material damage analysis and modeling.

If selected, you will play a significant role in the projects related to modeling and reliability testing of advanced chip packaging and other electronics applications. This includes working with NIST staff and external partners on setting up models to predict the behavior and investigate possible points of failure during the service lifetime of heterogeneous multilayered polymeric, metal, and semiconductor structures, identify crucial material parameters, and plan and execute experimental research to evaluate changes of these material parameters after aging. The results will be used to understand the root causes of the multilayer failures, providing a scientific basis for test method development, material selection, and product quality assurance for the semiconductor industry.

Key responsibilities will include but are not limited to:

• Developing finite element models of thermomechanical behavior of heterogeneous multilayered systems.
• Characterizing the degradation of materials and interfaces before, during, and after exposure to accelerated laboratory aging.
• Developing reliability models for complex advanced packaging systems.
• Providing technical leadership on finite element modeling of failure mechanisms in multilayered polymeric structures.
• Disseminating research results through presentations at conferences, publication of journal papers, and technical reports.

Qualifications

• U.S. citizenship is preferred
• Currently live in the United States
• Ph.D. in Physics / Mechanical Engineering / Electrical Engineering / Materials Science / Chemical Engineering
• Experience in nano- and micro-scale mechanical testing and materials characterization
• Experience in finite element modeling of heterogeneous systems
• Experience in advanced semiconductor packaging is preferred
• Strong oral and written communication skills
