Title:Semiconductor Device EngineerBelong. Connect. Grow. with KBR!KBR’s National Security Solutions team provides high-end engineering and advanced technology solutions to our customers in the intelligence and national security communities. In this position, your work will have a profound impact on the country’s most critical role – protecting our national security.Why Join Us?Innovative Projects: KBR’s work is at the forefront of engineering, logistics, operations, science, program management, mission IT and cybersecurity solutions.Collaborative Environment: Be part of a dynamic team that thrives on collaboration and innovation, fostering a supportive and intellectually stimulating workplace.Impactful Work: Your contributions will be pivotal in designing and optimizing defense systems that ensure national security and shape the future of space defense.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: OnsiteTravel Requirements: Minimal 0-20%Working Hours: StandardRequired 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 recordSecurity Clearance: Must possess the ability to obtain and maintain a U.S. Government clearance.
