Abstract
Provided is a more efficient method of manufacturing a GaN film by the atomic layer deposition (ALD), wherein a high crystalline GaN film containing very few impurities is manufactured using a monovalent gallium compound without high-temperature thermal treatment such as laser annealing. The method of manufacturing a crystalline gallium nitride thin film by the ALD comprises a step 1 of feeding a monovalent organogallium complex into a reaction chamber where a substrate temperature is 350° C. or less, and a step 2 of feeding a nitriding gas into the reaction chamber.
