  1. Introduces: Solar Substrate Separator, S3

  2. S3- “S Cubed” Solar Substrate Separation Equipment for separation of post wire saw substrate for delivery to batch processing or in-line solar substrate processing systems

  3. Solar Substrate Separation Challenges: • Manual Separation: • Labor intensive • Ergonomic and repetitive motion concerns • High wafer breakage rate • Other Automated Separation Methods: • Large foot print • Expensive consumables • Intolerant of varying wafer thicknesses and geometries

  4. Solar Substrate Separation Process: • Operator loads stacks of wet wafers onto a horizontal stack • As more material is added, the stack drops down into the equipment • When the loading is completed, the tool lid is closed, and automated separation begins

  5. Solar Substrate Separation Process: • The System gently separates the stack of wafers using a water jet enabling the top wafer to be removed from the stack. • Wafer is then delivered to conveyor delivery system for loading into cassettes or in-line systems • Wafer separation is a gentle process that has a low breakage rate

  6. S3 Features:

  7. S3 Visualization: • Automatic Cassette Loading: • Automated loading of multiple cassettes • Linear option • Rotary option (shown in slides)

  8. S3 Visualization: • Wet Separation: • Water is introduced to separate the stack of wafers • This process is illustrated below

  9. S3 Visualization: • Vacuum Belt Concept: • After the stack is sufficiently separated, a vacuum belt gently lifts the top wafer to carry it to the loading belt
