Research Title

Digital Twins for Atomic Layer Deposition Processes

Project Overview

The Chemical Sciences Division of NIST is seeking a postdoctoral researcher to join a multi-disciplinary team of scientists working on advanced modeling of atomic layer deposition (ALD) processes. The project will develop a suite of in situ metrology tools to quantify mass transport processes occurring during thermal ALD. Metrology data will support the development of computational fluid dynamics (CFD) and machine learning (ML) models of transport and surface reaction processes, with the ultimate goal of producing validated digital twins for thermal ALD processes. The team includes experts in vapor phase deposition processes, in situ optical metrology, micro‑electromechanical system (MEMS) design, numerical modeling, and machine learning. NIST has unique facilities for the development and application of fast and sensitive in situ diagnostics for vapor phase deposition processes. Multiple research‑grade ALD systems dedicated to oxide, metal, and sulfide film deposition are available, as well as optical measurements spanning the UV and mid‑IR wavelengths tailored for surface and gas‑phase processes.

Key Responsibilities

• Operating and maintaining multiple ALD systems and custom in situ optical setups
• Performing temporally- and spatially-resolved optical measurements during ALD
• Using and analyzing optical process data to validate transport models
• Publishing findings in peer‑reviewed scientific journals and presenting at conferences
