Job Description

We are seeking a highly motivated and hands‑on Semiconductor Device Engineer to join our team researching Gallium Nitride and Ga2O3‑based device development. This role is designed for an engineer with a strong foundation in semiconductor physics and a desire to work directly in a cleanroom environment. In this role, you will bridge the gap between virtual modeling and physical realization by fabricating test structures in our state‑of‑the‑art cleanroom, conducting DC/RF electrical testing, performing TCAD simulations, and inspecting devices using advanced microscopy. You will work closely with colleagues to accelerate technology development and optimize device performance.

Key Responsibilities:

• Cleanroom Fabrication & Process Support: Spend active time in the cleanroom environment assisting with process steps, managing test runs, and operating fabrication equipment (e.g., photolithography, wet/dry etching, thin‑film deposition).
• Electrical Characterization (DC & RF): Set up and execute parametric electrical testing. Perform DC measurements (I‑V, C‑V) and RF/high‑frequency measurements (S‑parameters) using manual or semi‑automated probe stations, parameter analyzers, and network analyzers.
• Microscopy & Metrology: Conduct physical characterization and failure analysis on fabricated devices using advanced microscopy tools, including Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM), and optical microscopes.
• Device Simulation (TCAD): Utilize TCAD simulation tools (e.g., Sentaurus, Silvaco) to model basic device physics, predict electrical behaviors, and guide physical experiments.
• Data Analysis & Reporting: Compile, analyze, and present experimental data. Compare electrical measurements against TCAD simulation results to identify discrepancies and suggest device improvements.
• Documentation & Safety compliance: Maintain rigorous documentation of cleanroom runs, testing protocols, and safety procedures.

Work Environment:

Location: Onsite Travel Requirements: Minimal 0‑20% Working Hours: Standard

Required Qualifications:

Education:

PhD degree in Electrical Engineering, Materials Science, Physics, Nanoengineering, or a closely related engineering field; or MS degree in the same discipline with 3+ years of microelectronics experience beyond graduate school.

Experience:

• 4+ years of hands‑on cleanroom experience (can include graduate research or internships)

Fabrication Skills:

• Familiarity with standard cleanroom protocols, safety standards, and basic microfabrication processing techniques.

Testing & Metrology:

• Experience with semiconductor parametric testing equipment (e.g., source measure units, lock‑in amplifiers).
• Hands‑on experience to DC/RF electrical characterization concepts.
• Direct experience operating optical microscopes; exposure to SEM or AFM is highly desirable.

Simulation & Software:

• Exposure to TCAD simulation software (e.g., Sentaurus, Silvaco, or COMSOL).

Communication & Teamwork:

Strong written and verbal communication skills, with a strong publication record

Security Clearance:

Must possess the ability to obtain and maintain a U.S. Government clearance.
