Job summary

pSemi Corporation in San Diego seeks a Senior Device Engineer in RFIC Design to develop high-frequency semiconductor devices for UltraCMOS process technology, partnering with process, device, and circuit teams.

You will drive device development, reliability testing, and modeling, using TCAD and silicon data to deliver manufacturable RF solutions for wireless and radar applications. Strong python/matlab skills and experience with RF characterization are required.

Qualifications

• Advanced working knowledge of semiconductor device physics, particularly SOI and RFSOI technologies.
• Hands-on experience with semiconductor process development and wafer fabrication.
• Experience working with CMOS and SOI process technologies.
• Basic understanding of RF device characterization and analysis.
• Experience with TCAD process and device simulation tools such as Synopsys or Silvaco.
• Proficiency in Python, MATLAB, or a similar scientific-computing environment for device and statistical analysis and data visualization.
• Demonstrated ability to analyze complex, multidimensional technical data using engineering and statistical-analysis tools and translate results into clear technical conclusions.
• Basic understanding of high frequency measurements (S-parameters, Load Pull, Harmonics, and Noise Figure).
• Experience extracting device figures of merit such as gm, gds, Cgs, Cgd, Ron, Coff, ft, fmax.
• Understanding of device reliability mechanisms including HCI, BTI, TDDB, and ESD.
• Basic understanding of how devices are used in RFIC design.
• Understanding of the interaction between semiconductor manufacturing and device performance
• Demonstrated ability to independently diagnose complex technical problems, evaluate alternative approaches, implement solutions, and verify results.
• Ability to work effectively across device, process, modeling, characterization, and circuit-design teams and communicate technical recommendations to diverse engineering audiences.
• Strong written and verbal technical communication skills, including the ability to document methods, present findings, and explain data-based recommendations.
• Demonstrated ability to plan and execute complex technical assignments independently under general direction.

Responsibilities

• Independently define and execute RFSOI Device development and technology optimization projects in collaboration with cross-functional teams.
• Develop a deep understanding of the relationship between RF performance, DC performance, device architecture, layout, process integration, and manufacturing variability.
• Utilize TCAD process and device simulations (2D/3D) to understand device behavior, evaluate technology options, and guide development decisions.
• Correlate TCAD simulation results with silicon measurements and characterization data.
• Work closely with Characterization team and create measurement plan for semiconductor devices such as DC, CV, RF, small-signal, large-signal, load-pull, and reliability methodologies.
• Analyze complex characterization data to identify performance trends, isolate anomalous behavior, explain non-ideal or non-classical effects, and recommend next steps for device, process, or model development.
• Apply statistical methodologies to evaluate device distributions, process capability, variability sources, and reliability trends.
• Support compact model development, device parameter extraction, and technology qualification activities.
• Author and present clear technical reports, present findings and data-based recommendations for technical and cross-functional audiences.
• Maintain controlled device and characterization documentation, technical data repositories, and internal knowledge resources.
