1. Engineering Evaluation
- Inspect the complete system and major components.
- Power on the system and perform initial diagnostics.
- Evaluate mechanical, electrical, pneumatic, gas delivery, vacuum, RF, and control systems.
- Identify failed, damaged, missing, or deteriorated components.
- Verify the original computer, controller, GUI software, communications, and I/O functions.
2. System and Process Chamber Cleaning
- Clean the equipment exterior and accessible internal cabinet areas.
- Clean the process chamber and process-related components.
- Clean the showerhead/electrode and wafer stage as required.
- Clean accessible gas lines and gas delivery components.
- Clean accessible vacuum lines and vacuum-side components.
- Replace deteriorated consumable components as required.
3. Process Chamber
- Inspect the chamber body, lid, showerhead/electrode, wafer stage/chuck, feedthroughs, fittings, seals, and related components.
- Inspect sealing surfaces and chamber vacuum integrity.
- Replace O-rings, seals, and normal service items as required.
- Repair or replace defective chamber components as required.
- Reassemble and leak-check the chamber.
4. Gas Delivery System
- Inspect MFCs, pneumatic valves, isolation valves, gas lines, fittings, and related components.
- Verify MFC and gas-valve operation.
- Repair or replace defective components as required.
- Perform appropriate leak checking of the gas delivery system.
5. Vacuum and Pressure-Control System
- Inspect tool-side vacuum lines, valves, vacuum gauges, pressure sensors, pressure-control components, fittings, and related hardware.
- Verify chamber pressure-control operation.
- Repair or replace defective tool-side vacuum components as required.
- Perform chamber and vacuum-line leak checking.
- A suitable test pump may be used by SemiStar during refurbishment and testing.
Note: The vacuum pump is not included with the equipment. The customer is responsible for providing a suitable vacuum pump for installation and operation.
6. RF / Plasma System
- Inspect and test the RF generator, RF matching network, RF cables/connections, electrodes, and related components.
- Verify RF power control and matching network operation.
- Verify plasma ignition and stable plasma operation.
- Repair or replace defective components as required.
7. Electrical and Control System
- Inspect power supplies, control boards, relays, sensors, switches, wiring, connectors, and related components.
- Inspect and test the original computer and system controller.
- Verify GUI operation, communications, and major I/O functions.
- Verify alarms, interlocks, emergency stop, and safety functions.
- Repair or replace defective components as required.
8. Mechanical, Pneumatic and Facility Interfaces
- Inspect mechanical assemblies, actuators, pneumatic valves/cylinders, switches, sensors, tubing, and fittings.
- Inspect tool-side cooling-water, CDA/pneumatic, exhaust, and other facility interfaces.
- Adjust, repair, or replace defective components as required.
9. Final System Testing
- Perform complete functional testing after refurbishment.
- Verify startup/shutdown sequences and chamber operation.
- Verify vacuum integrity, gas flow, and pressure control.
- Verify RF power, matching, plasma ignition, and plasma operation.
- Verify computer/controller/GUI operation.
- Verify mechanical and pneumatic functions.
- Verify alarms and safety interlocks.
- Correct issues identified during final testing as required.
10. Final Inspection and Refurbishment Report
- Perform final visual and functional inspection.
- Confirm the system configuration.
- Document major repairs and components replaced.
- Provide a SemiStar Refurbishment Report after refurbishment and final testing are completed.
Important: The exact repairs and replacement parts cannot be determined until we power on, evaluate, and troubleshoot this particular system. The above describes our general refurbishment process and scope.
