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) that 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, 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, and 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, especially 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 FMEAs.
• Skills in DoE design and data analysis tools (JMP, Spotfire).
• 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 master’s or PhD in Electrical Engineering, Physics, or Material Science and 5+ years of experience in a relevant job function.

Benefits

Salary: $125,000-$165,000 per year (good‑faith estimate).

Benefits and other eligible compensation include health, dental, vision, disability, and life insurance; 401(k) plan with company match; paid time off; annual bonus; and tuition reimbursement.
