• Process Analysis and Development:
  • Understand the role of PECVD in depositing essential dielectric layers, such as SiO₂ and Si₃N₄ for CMOS devices.
  • Investigate the impact of PECVD process parameters (e.g., precursor gas ratios, RF power, pressure, substrate temperature) on film stoichiometry.
  • Identify correlations between input parameters and key output metrics like film thickness and RI.
• Experimental Design and Execution:
  • Develop systematic experiments using Design of Experiments (DoE) techniques.
  • Perform thin film deposition runs on state-of-the-art equipment available at ams-OSRAM's fabrication facilities.
• Metrology and Characterization:
  • Characterize deposited thin films using ellipsometry to assess thickness and refractive index and Scanning Electron Microscopy (SEM) with Energy Dispersive X-ray Spectroscopy (EDX) to evaluate stoichiometric composition.
  • Evaluate process stability, within-wafer and wafer-to-wafer uniformity.
• Data Analysis and Optimization:
  • Analyze experimental data using statistical tools and regression models.
  • Propose optimized PECVD recipes that meet stringent CMOS specification targets.
  • Derivation of Fit and Response models for process parameter tuning to optimize process capability.
• Reporting and Communication:
  • Document all process steps, experimental results, and analysis findings.
  • Present progress in regular meetings with supervising engineers and researchers.
  • Compile a final thesis report containing conclusions, visualized data, and future recommendations.
