Key Responsibilities

  • Manage a cost-effective wafer fabrication process by providing engineering support to the production line to achieve the organization's targeted manufacturing performance.
  • Take full ownership of all engineering issues for the assigned process.
  • Maintain and support day-to-day manufacturing activities through real-time problem analysis and timely implementation of effective solutions.
  • Ensure smooth process flow with high quality, high yield, and low cost by working closely with Maintenance Specialists, Production Supervisors, and Shift Engineers to achieve committed targets.
  • Provide cross-functional, cross-department, and cross-fab support based on operational needs and priorities.
  • Train new engineers and share technical knowledge to support team development.
  • Support shift operations as needed and return to normal shift assignment for process/project work when assigned.
  • Take responsibility for trench etch processes within the poly team.

Requirements

  • Bachelor's degree in Electrical/Electronics Engineering, Mechanical Engineering, Materials Engineering, Chemical Engineering or a related discipline.
  • Around 2 years of experience with trench etch processes and the associated challenges, including profile control and process stability.
  • Ability to conduct real-time problem analysis for SPC OOC/OOS, defect failures, and FDC failures, and determine appropriate solutions by working with all relevant stakeholders.
  • Ensure all basic inline investigations are reported in real time to the relevant owners with complete and accurate details.
  • Ability to set up process recipes for newly introduced processes.
  • Ability to establish a robust process control system to maintain the lowest possible Wafer at Risk (WAR) level, maximize the signal-to-noise ratio for SPC and FDC, and minimize human dependency.
