Introduces Solar Substrate Separator S 3 3 S
Introduces: Solar Substrate Separator, S 3
3 S - “S Cubed” Solar Substrate Separation Equipment for separation of post wire saw substrate for delivery to batch processing or inline solar substrate processing systems
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
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
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

3 S Visualization: Automatic Cassette Loading: § Automated loading of multiple cassettes § Linear option § Rotary option (shown in slides)
3 S Visualization: Wet Separation: § Water is introduced to separate the stack of wafers § This process is illustrated below
3 S 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
3 S Visualization: Wafer Loading: § Wafers are then loaded into cassettes, as shown in the beginning of the presentation
