A method and chemical delivery system are provided for low temperature atomic layer deposition. Thus, methods of forming nitrogen-containing thin films by atomic layer deposition using a substantially water free hydrazine gas and plasma treatment are provided.

A nanoheterostructure includes a first inorganic component and a second inorganic component one of which is a matrix, and the other of which is three-dimensionally and periodically arranged in the matrix, and has a three-dimensional periodic structure whose average value of one unit length of a repeated structure is 1 nm to 100 nm.

Provided is a method of manufacturing a semiconductor device, including: forming a stacked metal nitride film including a first metal nitride film and a second metal nitride film on a substrate by alternately performing steps (a) and (b) a plurality of times, wherein the step (a) includes alternately supplying: a first metal source containing a first halogen element and a metal element; and a nitrogen-containing source to the substrate a plurality of times to form the first metal nitride film, and the step (b) includes alternately supplying: a second metal source containing a second halogen element different from the first halogen element and the metal element; and the nitrogen-containing source to the substrate a plurality of times to form the second metal nitride film.
