LTD - Manufacturing BE Metals Department Award

Recognition of an outstanding contribution towards onboarding critical tool sets. Supportorting spec updates, virtual factory transfers and technician training. Helping in the introduction of un-forecasted, first of a kind redistribution layer in record time.

• Applied Endura PVD Equipment
• Robotic mechanisms for PVD production tool sets
• Wafer Robotics handling

      - Closely inspected robot blades/bearings/touch pads for wafer handling and identified a 

         discrepancy in parts between tool sets causing high defect counts in the process. 

         Replaced and upgraded blades and resolved years of elevated defect counts.

• Slit Valve/Slit Doors using pneumatics understanding and troubleshooting experience
• Fiber optics cables and amplifier handling
• Chamber pressure Testing using Baratron/Ion Gauges
• DC Power Supplies for PVD Tesing
• RF Generator Plasma Source for PVD pedestal wafer chucking

     - Owned and performed a fab wide safety audit for proper solenoid and bolt installation on 

        all RF sources. Upgraded equipment solenoid valves leading to all RF Generators due to 

        high cost leak incidents.
