Abstract:
A system of depositing a thin film on a substrate, the system comprising,a target,a laser for providing a laser beam for ablating the target with the laser beam creating a plasma plume having charged species and neutral species,a focusing means for focusing the laser beam,a shield for shielding the substrate to prevent species of the plume from traveling from the target to the substrate through a direct line of sight between the target and the substrate, anda magnet means for creating a magnetic field for deflecting the charged species in the plume towards the substrate to deposit the charged species on the substrate, the deflection being orthogonal to the plume and to the magnetic field, the deflection is an orthogonal v X B Lorentz magnetic deflection with the magnetic field having a vector B, the charged species having a velocity vector v, and the deflection being orthogonal to both vectors v and B to orthogonally deflect the charged species around the shielding and towards the substrate, the thin film having a same material as the target.
