PLD System

PLD / Laser-MBE System Lines

  • The Laser Molecular Beam Epitaxy System (MBE) is a PLD (Plused Laser Deposition) equipment that uses a high-power pulsed laser to melt sputtering targets during PVD.
  • It enables atomic control of thickness during deposition of unit or multi-element thin films to manufacture ultra-thin films or super-lattice thin films and can manufacture thin films with the same composition ratio as raw materials which is used for high-quality thin films. It is largely classified into Compact type and Mobile Combi type.
