Responsibilities
Lead and execute the design of high voltage LNDMOS devices, considering breakdown voltage, on-resistance, charge balance, and ruggedness. Utilize CAD and TCAD simulation tools to model electrical, thermal, and reliability characteristics, iterating designs to achieve optimal performance
Collaborate closely with process engineers to define and refine process flows for LNDMOS device fabrication. Evaluate and select suitable materials, doping profiles, and process steps to achieve desired device specifications, manufacturability, and yield
Plan and conduct electrical, thermal, and reliability characterization of fabricated devices. Analyze test data to validate models, extract key device parameters, and identify areas for improvement
Research and implement new architectures, materials, and device structures (e.g., trench, superjunction, shielded gate) to push the boundaries of LNDMOS performance. Stay abreast of academic and industry advances, proposing innovative solutions for future products
Investigate device failures using advanced diagnostic tools (SEM, TEM, FIB, EDX, etc.), root-cause analysis, and simulation. Recommend corrective actions and support continuous improvement efforts
Interface with teams across device design, process engineering, test and characterization, packaging, and product engineering to ensure seamless development and launch of LNDMOS-based products
Produce detailed technical documentation, including design specifications, simulation reports, process flows, and characterization results. Present findings to both technical and non-technical stakeholders
Support product qualification cycles by designing and executing reliability tests (e.g., HTRB, TDDB, ESD, UIS) and working with quality teams to meet international standards and customer requirements
Analyze manufacturing data to identify yield detractors and cost drivers, working with manufacturing teams to implement solutions for device and process improvement
Provide guidance and expertise to application engineers, field teams, and customers for integrating LNDMOS devices into end applications, troubleshooting, and ensuring optimal performance
