• Define maintain and continuously improve process recipes specifications and control plans
• Lead root cause analysis and containment for excursions parametric shifts and yield detractors using structured problemsolving methodologies
• Drive longterm process improvements aligned with technology roadmaps and product requirements

CMP Process Responsibilities

• Own and optimize CMP processes including:
  • Oxide silicon and Poly Silicon
  • Slurry selection pad conditioning strategies and consumables lifecycle
  • Defectivity reduction (scratches dishing erosion) WIWNU and surface quality control
• Interface with equipment and materials suppliers to drive tool matching material optimization and cost reduction
• Lead CMPrelated yield learning defect reduction and tool/process qualification activities

Diffusion / Thermal Process Responsibilities

• Own diffusion and thermal process flows including:
  • Oxidation (dry and wet)
  • Furnace and RTP anneals (spike soak and drivein)
  • Dopant activation junction depth control and thermal budget optimization
• Improve sheet resistance control uniformity repeatability and process margins
• Drive equipment performance improvements and recipe optimization for highvolume manufacturing

Manufacturing & CrossFunctional Engagement

• Partner closely with manufacturing equipment engineering yield and device integration teams to maximize line performance
• Provide rapid technical response to production issues and line interruptions
• Lead process change management including qualification plans documentation and FMEAbased risk assessments

Data Analysis & Continuous Improvement

• Apply statistical methodologies (SPC DOE regression multivariate analysis) to guide process decisions
• Analyze inline metrology defect inspection parametric and electrical test data to identify trends and opportunities
• Develop and deploy robust process control strategies to prevent recurrence of known failure modes

Mentorship & Organizational Impact

• Act as a technical mentor for senior and midlevel process engineers
• Contribute to fabwide best practices documentation standards and knowledge sharing
• Influence technical direction beyond assigned modules through experience judgment and credibility

Qualifications :

Required Qualifications

• Bachelors degree in Chemical Engineering Materials Science Electrical Engineering Physics or a related discipline
