Senior Semiconductor Device Modeling Engineer

RTN 2 (Raytheon IDMS)
Andover, MA 01810

An exciting opportunity exists for a semiconductor device modeling engineer to join our fast-paced microelectronics group as part of the Foundry Services / Design Enablement Section within the Microelectronics Engineering & Technology (MET) Department. MET, part of Raytheon Missiles and Defense (RMD) business unit, develops, designs, 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 models to support the development of products fabricated in our III-V semiconductor foundry. These models will be used by our MMIC design teams to create Monolithic Microwave Integrated Circuits (MMICs) for use in advanced defense electronic systems.

Responsibilities will 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 models
Development of advanced device model formulations and model extraction algorithms
Release of 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
This position will require a secret clearance.

Required Skills

Minimum of 4 years of experience in a semiconductor device characterization or modeling role
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

U.S. Citizenship status is required as this position will need a U.S. Security Clearance within 1 year of start date. Except in rare circumstances, only U.S. citizens are eligible for a security clearance.

Desired Skills

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
Basic network theory
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 Angelov, EEHEMT, BSIM4, PSP, etc.
Experience with setup/development/use of Keysight IC-CAP or other commercial and/or custom measurement and parameter extraction software

Required Education

BS in Electrical Engineering or Applied Physics or other related Engineering discipline. MS degree preferred.

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