About this opportunity
Polar Semiconductor, LLC lists this Principal GaN Technology Development Engineer opportunity in bloomington, Minnesota. Review the employer’s description below for duties, qualifications and application requirements.
Job description
JOB SUMMARY
Contribute to the development/transfer, optimization, and documentation of the overall process flow and macro modules required to fabricate reliable, manufacturable devices on GaN on Silicon (HEMT), which meet parametric and performance goals. Characterize, evaluate, and document semiconductor devices to ensure reliability and performance to quality standards. Evaluate new opportunities for development and/or transfer of new semiconductor technology and processes.
DUTIES AND RESPONSIBILITIES
Set up and perform process and device simulations to determine initial process parameters, capabilities, and direction for optimization of new process flows.
Design and perform experiments and analyze the results to determine the process sequences and parameters which will yield the target device parameters, by using the results of the process simulations or initial test lots as a starting point.
Analyze data (electrical, in-process measurement or visual inspection) from the fabrication of test lots to determine which parameters require additional optimization.
Work with Process Engineering to develop, characterize, and optimize process modules.
Support the processing of the initial test chip and transfer lots fabricated with the new process to identify and correct any problem areas and work to achieve first-pass success.
Provide inputs to and work with Device Engineers to develop layout rules for the process being developed, using equipment specifications and experimental data.
Recommend test structures for and contribute to the layout of test chip mask sets to aid in developing the new process and evaluating specific process‑dependencies of device parameters.
Provide weekly, monthly, quarterly development updates to upper management and external customers.
Support company initiatives, such as quality, safety and environmental management, CQI, 5S, yield management, and cost containment.
Perform other duties as required.
KNOWLEDGE, SKILLS, AND ABILITIES
Strong process integration knowledge of GaN on silicon HEMT power devices
Strong knowledge of semiconductor device physics, specially III-V nitrides
Working knowledge of key process modules (Photo, Etch, Thin Films, CMP, MOCVD, etc.)
Broad knowledge of GaN market trends and new opportunity evaluation experience preferred
Process Integration Experience in CMOS/BCDMOS or Discrete IGBTs/MOSFETs a plus
Experience in Process Flow Design to Achieve Manufacturability Metrics and Meet Electrical Test Targets
Experience with and Understanding of Electrical Test Data and its Correlation to Process and Cross-sectional data
Experience Interpreting Failure Analysis Results and Familiarity with Failure Analysis techniques
Experience with Power Packaging including Assembly and Reliability issues
Experience in Backend (BGBM, STM, etc.) Processes
Experience in Development of Process, Technology and Design FMEA’s
Skills DoE Design and Data Analysis Tools (JMP, Spotfire)
TCAD Process Simulations
Reading and Interpretation of Design Layouts
Abilities Working with and Interpreting Information/Data between Design and Process Teams Driving for Solutions and Collaborating on Cross‑functional Teams
Technical Leadership Ability (Education, experience and communication skills) Typically requires a Masters or PhD in Electrical Engineering, Physics or Material Science and 5+ years of experience in a relevant job function.
What We Offer
Salary: $125,000-$165,000 per year (good‑faith estimate)
Benefits & Other Eligible Compensation: Includes health, dental, vision, disability and life insurance, 401(k) plan with company match, paid time off, annual bonus, and tuition reimbursement.
