Abstract:
Systems and methods for depositing a thin film layer onto a flexible ferromagnetic substrate include a porous block in a deposition zone and a plurality of magnets embedded within the porous block. The magnets provide a downward force on a flexible ferromagnetic substrate being transported over the porous block, e.g., in a reel-to-reel system. Pressurized gas is forced upward through the porous block, providing an upward force that balances the downward force and supports the substrate at a desired height above the porous block. The substrate is thus held flat during transport through the deposition zone, enabling uniform deposition of a thin film layer.

Claim (Index 1):
A system for depositing a thin film semiconductor layer onto a flexible substrate, comprising:\n a pay-out roll and a take-up roll, collectively configured to transport a flexible substrate through a deposition zone; a porous block having a substantially flat proximal surface disposed within the deposition zone and configured to support the substrate with air pressure, and a distal side opposite the substantially flat upper surface; a plurality of magnets embedded within the porous block; a pump configured to force pressurized gas through the porous block and thereby to maintain a gap between the substrate and the proximal surface of the porous block, wherein the pressurized gas is dispensed uniformly across the deposition zone, such that the gap is equal at all points across the deposition zone; a supply of a first solution containing cadmium; a first solution dispenser configured to dispense the first solution onto the substrate at a first longitudinal position within the deposition zone; a supply of a second solution containing sulfur; a second solution dispenser configured to dispense the second solution onto the substrate at a second longitudinal position within the deposition zone; and a heater configured to heat the substrate to a temperature sufficient to nucleate cadmium sulfide when the first and second solutions combine.
