1. Introduces: Solar Substrate Separator, S 3

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

3. 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. 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. 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. FeatureSpecification Peak single head separation throughput1200 Wafers Per Hour Wafer Sizes125X125, 156X156, 210X210 Pseudo and square 160 Micron and thicker – Tolerant of varying wafer thicknesses Facilities Requirements100~230 VAC 50/60 Hz, Less than 15 Amps 10 L/hour water Compressed Air ¼” supply @ 80 PSI Wafer HandlingWafers can be kept wet or dry Wafer Breakage Rate<.5% Single head separation footprint21” Wide X 32” Long X 48” Tall excluding controls cabinet and substrate handling conveyor system ConsumablesInexpensive urethane wear surfaces that are easily replaced Equipment InterfaceSupports in-line and batch processes

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

29. Wet Separation:  Water is introduced to separate the stack of wafers  This process is illustrated below

48. Vacuum Belt Concept:  After the stack is sufficiently separated, a vacuum belt gently lifts the top wafer to carry it to the loading belt

69. Wafer Loading:  Wafers are then loaded into cassettes, as shown in the beginning of the presentation
