Responsibilities

• Cleanroom Fabrication & Process Support: Spend active time in the cleanroom environment assisting with process steps, managing test runs, and operating fabrication equipment (e.g., photolithography, wet/dry etching, thin-film deposition).
• Electrical Characterization (DC & RF): Set up and execute parametric electrical testing. Perform DC measurements (I-V, C-V) and RF/high-frequency measurements (S-parameters) using manual or semi-automated probe stations, parameter analyzers, and network analyzers.
• Microscopy & Metrology: Conduct physical characterization and failure analysis on fabricated devices using advanced microscopy tools, including Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM), and optical microscopes.
• Device Simulation (TCAD): Utilize TCAD simulation tools
