PLD System

PLD / Laser-MBE System Lines

  • Laser MBE System (Laser Molecular Beam Epitaxy system)은 PVD시 스퍼터링 타겟을 녹이기 위하여 고출력 펄스형 레이저를 이용하는 PLD(Plused Laser Deposition) 장비입니다.
  • 단원소 혹은 다원소 박막의 증착 도중 이들의 두께를 원자단위로 제어하는 것을 가능하게 해주어 초박막(Ultra-Thin Film)이나 규칙 격자(Super Lattice) 박막 제조가 가능하게 해주며 원재료와 동일한 조성비를 갖는 박막의 제조가 가능하여 고품질 박막 제조에 활용되고 있으며, 크게 Compact 타입과 Mobile Combi 타입으로 분류됩니다
