Abstract
A superlattice film is formed by introducing a mixture of a first gas reactant capable of only plasma-excited chemical reaction and a second gas reactant capable of both plasma-excited chemical reactions into a reaction chamber, discontinuously carrying out plasma-excited chemical reaction, and continuously carrying out light-excited chemical reaction, thereby alternately depositing on a substrate a thin film layer which is formed when the plasma- and light-excited chemical reactions are carried out and another thin film layer which is formed when the plasma-excited chemical reaction is interrupted, thereby forming a thin film of alternately deposited layers.
