Deposition Materials

Metal-organic precursors help create the basic building blocks of electronic chips. Each layer is gradually added to a special evaporation chamber or epitaxial chamber. When the precursor contacts the heated wafer, they leave deposits and form semiconductors. The vapor phase reactant (chemical precursor) deposits/grows a thin film on the substrate by chemical vapor deposition (CVD) or atomic layer deposition (ALD).

Alfa Chemistry is a leading supplier of semiconductor solutions with extensive experience. We can provide our customers with a variety of deposition materials, which are chemistries enabling thin film CVD and ALD of metals, oxides, and nitrides for the next gen advanced logic and memory devices.

What Are CVD and ALD?

CVD: A chemical process often used in semiconductor chip manufacturing to deposit thin films of various materials

  • Continuous film growth
  • Gas mixed in the reaction chamber
  • The thickness is controlled by the reaction time (the ability to grow very thin films is limited)

ALD: Thin film deposition technology based on the sequential use of gas-phase chemical processes (a sub-category of chemical vapor deposition)

  • Self-terminating
  • Conformal film
  • Reactive gas introduced separately
  • Thickness control by the number of cycles (excellent film thickness control)
