Core Responsibilities

Quality Management

  • Monitor and maintain quality standards across wafer fabrication processes.

  • Develop and maintain quality documentation including Control Plans, PFMEA, SOPs, quality procedures, and audit records.

  • Ensure compliance with ISO 9001, customer requirements, and internal quality systems. Chair CRB (change request board) to review and make disposition on change request from foundry fabs.

Process Quality & Yield Improvement

  • Analyse foundry line yield loss, defect density, process capability, and quality metrics.

  • Drive continuous improvement projects (CIP) to reduce defects and improve manufacturing performance.

  • Monitor SPC charts and process control systems to identify drift to pro-actively prevent excursions and risks.

Problem Solving & Corrective Actions

  • Lead root cause analysis using (not limited to ) 8D, 5 Why, Fishbone, and statistical tools.

  • Investigate quality excursions (NC), wafer defects, customer complaints, and reliability failures.

  • Implement and verify CAPA effectiveness to prevent recurrence.

Customer Quality Management

  • Act as the primary interface between customers and manufacturing teams on quality-related issues.

  • Support customer audits, quality reviews, RMAs, NC, CAPA and corrective action reports.

  • Prepare customer quality reports and communicate quality performance metrics.

Reliability & Product Qualification

  • Support process qualification, technology transfer, and new process & product introduction activities.

  • Review reliability data and ensure products meet qualification requirements.

  • Participate in wafer fabrication change management and risk assessment activities.

Audits & Compliance

  • Conduct internal process audits and quality system audits.

  • Track corrective actions from audit findings through closure.

  • Maintain audit readiness for customers and certification bodies.

Required Qualifications
  • Bachelor's Degree in Electrical Engineering, Electronics Engineering, Materials Science, Chemical Engineering, Physics, or related field.

  • 5 -10 years of experience in semiconductor wafer fabrication, foundry manufacturing, or semiconductor quality engineering.

  • Knowledge of FEOL and BEOL manufacturing processes.

  • Technical Skills

    • Statistical Process Control (SPC), Failure Analysis (FA), FMEA / PFMEA, CAPA, 8D Problem Solving, DOE (Design of Experiments), Yield Analysis, Reliability Engineering, ISO 9001 (IATF 16949 an advantage)

    • Minitab, JMP, Excel, SQL (preferred)

Preferred Experience
  • Semiconductor foundry or fab environments such as CMOS, RF, Mixed-Signal technologies, Silicon Photonics an added advantage.

  • Customer & foundry quality management and audit experience.

  • Technology transfer and process qualification projects.

  • Lean Six Sigma certification preferred.
