Job description

Process Technician - Keep the World's Most Advanced Production Running

A job at TSMC Arizona offers an opportunity to work at the most advanced semiconductor fab in the United States. TSMC Arizona's first fab will operate it's leading-edge semiconductor process technology (N4 process), starting production in the first half of 2025. The second fab will utilize its leading edge N3 and N2 process technology and be operational in 2028. The recently announced third fab will manufacture chips using 2nm or even more advanced process technology, with production starting by the end of the decade. America's leading technology companies are ready to rely on TSMC Arizona for the next generations of chips that will power the digital future.

At TSMC Arizona, Process Technicians are not just operators-they are the production guardians of the most advanced semiconductor fab in the U.S. When you are on shift, you hold direct responsibility for production stability, making time-critical decisions, and ensuring billions of transistors are manufactured flawlessly. Your judgment directly affects wafer yield, line stability, and multi-million-dollar tool performance.

Module Process Technician
Our Process Technicians are assigned to specialized engineering modules, such as Lithography (LIT), Etch (ETC), Chemical Vapor Deposition (CVD), Physical Vapor Deposition (PVD), Diffusion (DIF), Epitaxy (EPI), Chemical Mechanical Polish (CMP), Metrology (ME), and Yield Excellence (YED). Each module plays a critical role in semiconductor manufacturing, and technicians are trusted to maintain stability and quality within their assigned area.


Quick Snapshot of Your Role

  1. Monitor & Operate Automated Systems
    Independently run production shifts by monitoring wafer flow, tool performance, and system dashboards to ensure every step meets standard.
  2. Respond to Alarms & Analyze Data
    Act immediately when alarms occur, apply decision trees/SOPs, and collect system data to trace abnormalities and prevent recurrence.
  3. Collaborate Across Teams for Stability
    Work closely with engineers and teammates to restore stability, refine procedures, and drive continuous improvements.
  4. Manage Multiple Tasks & System Checks
    Balance lots, system alerts, and tool checks in parallel to set the right priorities to safeguard yield and production output.

What You Will Do

  1. Run Production Shifts: Operate and oversee automated systems that control wafer flow and tool performance.
  2. Respond with Speed & Judgment: Resolve abnormalities following SOPs and decision trees, while applying judgment for urgent cases outside SOP coverage.
  3. Analyze Data for Insights: Use system tools and reports to identify patterns, trace root causes, and document solutions.
  4. Coordinate with Engineers: Collaborate to troubleshoot issues, stabilize processes, and continuously improve line performance.
  5. Grow into Leadership: With experience, take on shift coordination, lead daily meetings, and mentor junior teammates that leads to opportunities in shift leadership and cross-team improvement projects.
