AMS, part of Raytheon Missiles and Defense (RMD) business unit, designs, develops, and manufactures compound semiconductor devices, microwave/millimeter-wave integrated circuits, and modules for defense applications. As a Senior Semiconductor Device Modeling Engineer working with our advanced GaN and GaAs technologies, you will be responsible for the generation of active and passive compact circuit simulation models to support the development of products fabricated in our III-V semiconductor foundry. These models will be used by our MMIC design teams across Raytheon to create Monolithic Microwave Integrated Circuits (MMICs) for use in advanced defense electronic systems.

Responsibilities may include the following:
  • Design and layout of device modeling test structures and chips
  • Evaluation, use, and support of hardware and software for measurement and parameter extraction
  • Definition and execution of device characterization test plans including static & pulsed I-V, C-V, CW & pulsed bias S-Parameter, load/source-pull, TOI, and noise measurements
  • Analysis of parametric test data, collection and analysis of modeling device data, and extraction of device compact models
  • Development of advanced device model formulations and model extraction algorithms
  • Release of compact models into MMIC Process Design Kits (PDKs) in Keysight ADS, and publication of device model documentation and foundry design manuals
  • Assisting device and process engineers in analysis and understanding of the detailed performance of various semiconductor active and passive devices through direct measurement and/or TCAD simulation
  • Assisting EDA engineers in development and testing of MMIC PDKs in Keysight ADS
  • Work with MMIC design teams to understand model limitations and opportunities for improvement

NOTE: This position can be either a Sr. Electrical Engineer I (G08) or Sr. Electrical Engineer II (G09) based on the candidates qualifications as they relate to the skills, experience and responsibility requirements for the position.

Required Education, Skill, and Experience:
  • BS in Engineering or Applied Physics, or other related discipline
  • Minimum of 4 years of experience in a semiconductor device characterization or modeling role
  • Experience with semiconductor device physics and network theory/microwave engineering concepts
  • Hands-on experience with semiconductor device characterization (measurement setup and execution) such as static & pulsed I-V, C-V, CW & pulsed bias S-Parameter, load/source-pull, TOI, and noise measurements
  • Hands-on experience with device/circuit simulation using SPICE or related simulation tools
  • US Citizenship is required
U.S. Citizenship status is required as this position will need a U.S. Security Clearance within 1 year of start date.

Desired Education, Skills, and Experience:

  • MS degree in Engineering
  • Have a background in III-V compound semiconductors as well as a thorough knowledge of the entire model development process including test structure design, parameter extraction, model validation, and preparation of model documentation/review packages
  • Experience with:
    • Semiconductor device physics concepts with emphasis on compound semiconductor HEMTs
    • Lumped element equivalent-circuit models for high-frequency transistor devices
    • Non-linear compact model parameter extraction and validation techniques
    • Verilog-A behavioral modeling language and its use for compact model development including direct experience developing advanced device model formulations and model extraction algorithms
  • Hands-on experience with high-frequency (microwave/millimeter wave) and large-signal/high power test equipment such as Keysight or Anteverta NVNAs
  • Experience using statistical data analysis tools such as MATLAB, JMP, or Excel
  • Experience with scripting languages such as Python in a Linux environment
  • Experience with multi-physics simulations especially for electromagnetic and electro-thermal analysis
  • Knowledge of power amplifiers, low-noise amplifiers, high power switches/limiters, and related circuits
  • Understanding of III-V integrated circuit manufacturing processes and concepts
  • Experience with field effect transistor models such as MVSG, ASM-HEMT, Angelov, EEHEMT, PSP, BSIM4, etc.
  • Experience using Keysight Advanced Design Systems and Cadence Virtuoso integrated circuit design platforms (schematic capture, layout, verification, data visualization, and simulation engines)
  • Experience with setup/development/use of Keysight IC-CAP or other commercial and/or custom measurement and parameter extraction software
Security: Will require Department of Defense (DoD) Secret level security clearance; current clearance preferred.

This position requires the ability to obtain and hold a DoD secret security clearance.

This position requires the successful issuance, transfer or maintenance of any clearances and/or accesses necessary for the position. Non-US citizens may not be eligible to obtain a security clearance. The Defense Counterintelligence and Security Agency (DCSA), an agency of the Department of Defense, handles and adjudicates the security clearance process. Security clearance factors include, but are not limited to, allegiance to the US, foreign influence, foreign preference, criminal conduct, security violations and drug involvement. Additional detail regarding security clearance factors can be obtained by accessing the DSCA website at:

This position requires either a U.S. Person or a Non-U.S. Person who is eligible to obtain any required Export Authorization.175101
