  • Patent number: 8092659
    Abstract: A multi-chamber processing system is described for depositing materials on multiple workpieces (wafers, display panels, or any other workpieces) at a time in a vacuum chamber. The system includes a sputtering chamber and a separate pre-clean chamber, where wafers can be transferred between the two chambers by a robotic arm without breaking a vacuum. The wafers are mounted one-by-one onto a rotating pallet in the pre-cleaning chamber and sputtering chamber. The pallet is firmly fixed to a rotatable table in the sputtering chamber. Copper tubing in the table couples RF energy to the wafers, and a liquid running through the copper tubing controls the temperature of the wafers. Multiple targets, of the same or different materials, may concurrently deposit material on the wafers as the pallet is rotating. Multiple magnets (one for each target) in the magnetron assembly in the sputtering chamber oscillate over their respective targets for uniform target erosion and uniform deposition on the wafers.

  • Patent number: 8080729
    Abstract: Solar cells include bus bars and high aspect-ratio gridlines that are printed on a substrate, and localized melting is induced to slump or flatten the gridline “vertex” portions that are disposed on the bus bars, while maintaining the high aspect-ratio of gridlines portions disposed on the substrate between the bus bars. The localized melting process is induced using one of several disclosed methods, such as rheological melting in which the two printed inks produce a compound that is relatively liquid. Localized melting is also induced using a deliquescing material (e.g., a flux or a solvent film) that is applied to the bus bar or gridline material. Also, eutectic melting is induced using a processing temperature that is between a melting point of the combined gridline/bus bar inks and the individual melting points of the inks alone. Laser-based melting and the use of copolymers is also disclosed.

  • Patent number: 8038858
    Abstract: An apparatus for deposition of plasma reaction films includes a substrate for the deposition of either thin or thick films. The substrate also allows for a film deposition which adheres to the substrate, and also films which may be removed after deposition. The cathode may be fabricated from individual wires, or it may be fabricated from a single conductor. A macro-particle filter which preferentially traps larger particles may be introduced between a porous cathode and the deposition surface. The macro-particle filter may also carry electrical current as is useful for generating a magnetic field such that a Lorentz force acts preferentially on ionized particles, allowing them to pass through the filter while trapping macroparticles that are not influenced by the magnetic field.
