Your Role

Key responsibilities in your new role

Epitaxial Growth & Recipe Development

• Design GaN epitaxial structures (e.g., buffer layers, superlattices, andHEMT structures) based on specific device performance targets

• Direct hands-on MOCVD (Metal-Organic Chemical Vapor Deposition) recipeoptimization

Process Integration & Manufacturability

• Transition new epitaxial processes from R&D into high-yield, high-volumemanufacturing

• Address manufacturability hurdles like defect density, wafer stress, andlayer uniformity

Data Analytics & Metrology

• Utilize Design of Experiments (DOE) and Statistical Process Control(SPC) to monitor and improve processes

• Analyze characterization data using techniques like SEM, TEM, AFM, andXRD to correlate material properties to final device performance

Strategic Leadership & Cross-Functional Work

• Influence long-term product technology roadmaps and advise management onmaterial and equipment investments

• Act as a mentor to junior and senior engineers, establishing technicalbest practices across the team

• Collaborate with device, process integration, and failure analysis teamsto rapidly resolve issues.
