THIN FILM FORMATION BY ATOMIC LAYER GROWTH AND CHEMICAL VAPOR DEPOSITION

摘要

A method for forming a thin film on a substrate using a showerhead includes forming an atomic layer deposition (ALD) film and a chemical vapor deposition (CVD) film continuously, or forming a thermal ALD film and a plasma ALD film continuously, by using a showerhead including an upper compartment and a lower compartment which is disposed underneath and overlapped by the upper compartment as viewed in an axial direction of the showerhead and is not gas-communicated with the upper compartment.
