Trek’s Model 646 software-driven Electrostatic Chuck Supply offers an array of features that provide significant benefits while accommodating a variety of demanding applications. Model 646 incorporates Trek technology which has demonstrated increases in efficiency and throughput equal to three times that of other supplies. Virtual elimination of sticky wafer and wafer popping issues ensures better control over particle contamination.

Given the versatility and performance of the Model 646, it can be used in multiple unique tools/processes, thus eliminating the need to specify a new supply for each unique tool/process in a facility.

Typical Applications Include
  • Electrostatic-driven handling of materials
  • Semiconductor wafer processing
  • Non-mechanical transfer of flat panels or other processing materials sensitive to mechanical handling
Features and Benefits
  • Supports both Coulombic and Johnsen-Rahbek ESC technologies
  • User configurable for custom clamp and declamp sequences and wave shapes
  • Electrostatic chuck profiles can be uploaded to the unit and stored internally via a user-friendly software interface
  • Reduces backside gas errors, increases throughput, and eliminates sticky/popping wafer issues
  • Lockable front panel control interface
  • Ability to control parameters such as over-current, wafer-present and wafer-clamped thresholds, clamp voltage,offset voltage and internal or external amplitude/offset control
  • Wafer detection includes no wafer, wafer present or wafer clamped status
  • Includes in-process-adjustable amplitude/offset and output-control versatility
  • Output can be controlled by back panel I/O, serial computer command or front panel controls
  • NIST-traceable Certificate of Calibration provided with each unit
