Concept of ALD

  • Atomic layer deposition (ALD) is a self-limiting film growth method by the alternate exposure of chemical species
  • Atomic later deposition (ALD) consists of essentially four steps 1. Precursor exposure
    2. Purging of the precursors and by-products
    3. Exposure of the reactant
    4. Purging of the reactants and by-products
