Module Sustaining:

• On-call Duty: Coverage of operational, automation, and hardware issues, disposition E3 abort, tool alarm, layer targeting OOCs, and inline defect tracer.
• Independently and successfully qualified the module and created RFC spec.
• Developed and wrote quality effective form (QEF) RFC BKM in SPEC for scrap reduction and disposition
• Performed routine maintenance and calibration of etch equipment, maintaining an equipment uptime of [90%+]
• Utilized SPC techniques to monitor process stability and control, leading to a [98%] reduction in process variation

Layer sustaining and development:

• Own several layers in the FE segments in the metal gate segment and completed the APC setup.
• Created a new station monitor and SPC chart for a specific layer in the metal gate and improved the inline product.

Defect reduction:

• Conducted root cause analysis for etch-related defects and implemented corrective actions, improving the quality of critical layers.
• Participated in cross-functional teams to address cost reduction initiatives.

• Designed ion cluster impact on nanoparticles lens with the help of SIMION software for calculating electric fields for electrodes of defined voltages and ion trajectories
• Assumed accountability in organizing, executing, and evaluating experiments to enhance fabrications of iron oxide, core-shell iron oxide nanoparticles through magnetron sputtering techniques
• Researched temperature-induced morphology, crystal structure, phase, size, and magnetic properties of the iron oxide, core-shell iron/iron oxide, and iron nitride nanoparticles
• Performed statistical analysis (SPC/DOE) on the thin film deposition of the metal bases on the different parameters such as vacuum pressure, gas flow rate, and power supply
• Utilized AutoCAD in designing machine drawing for various parts of magnetron sputtering system and process specifications
• Led two projects to model, simulate pure and core-shell nanoparticle and data analysis the radiation effect to impact on experimental studies
• Held responsibility for distributing research findings in several international conferences and scientific journals
• Trained other graduate students by leading, guiding, and assisting them with the goal of preparing them to execute flawlessly magnetron sputtering device for cluster and thin film deposition
• Equipment vendors contracts to mitigate issues in turbomolecular pump (TMP) and machine shop technician to create and change parts of the magnetron sputtering system.
