Device Fabrication and Electrical Characterization Scientist at Core4ce – WPAFB, Ohio

Core4ce

Device Fabrication and Electrical Characterization Scientist
1193-383

The successful candidate will research, fabricate, and characterize wide bandgap (WBG) and ultra-wide bandgap (UWBG) semiconductor devices for logic, power, and RF electronics operating in extreme temperature and radiation environments. This role combines cleanroom microfabrication, advanced electrical testing across temperature, and physics-based modeling to connect device behavior to material properties and defects.

Responsibilities:

• Research and evaluate WBG/UWBG semiconductor materials and device concepts for logic, power, and RF applications in high-temperature and radiation environments.
• Design and fabricate test structures and devices using microfabrication processes, including:
  • Photolithography (and/or e-beam as applicable)
  • Metallization and liftoff
  • Atomic layer deposition (ALD)
  • Reactive ion etching (RIE) / dry etch processing
• Perform electrical characterization of semiconductor devices and test structures, such as:
  • Diodes, transistors, and MIS capacitors
  • I–V and C–V measurements
  • Temperature-dependent electrical testing (e.g., cryo to high temperature as relevant)
• Develop and apply physics-based device/material models to interpret data and explain performance trends under temperature and radiation stressors.
• Extract and correlate key material/device parameters (e.g., mobility, carrier density, conductivity, interface/defect density, contact resistance) with measured device behavior.
• Document experimental methods and results; prepare internal reports, manuscripts, and/or conference presentations as needed.
• Collaborate with cross-functional teams (materials growth, processing, modeling, reliability/radiation testing) to drive device iteration and improvement.

*This position is designed to be flexible, with responsibilities evolving to meet business needs and enable individual growth.

Required Qualifications:

• PhD in Electrical Engineering, Materials Science, Physics, or related field (or equivalent experience).
• Hands-on experience with semiconductor device fabrication in a cleanroom environment.
• Proficiency in one or more of: lithography, metallization/liftoff, ALD, RIE/dry etch.
• Experience performing electrical characterization of semiconductor devices (I–V, C–V; parameter extraction).
• Solid foundation in semiconductor device physics (transport, contacts, interfaces, defects/traps).
• Ability to build or implement physics-based models and interpret experimental results (e.g., using MATLAB, Python, TCAD, or similar).
• Strong documentation, communication, and data analysis skills.
