摘要:
A method of forming a high dielectric film using atomic layer deposition (ALD), and a method of manufacturing a capacitor having the high dielectric film, include supplying a precursor containing a metal element to a semiconductor substrate and purging a reactor; supplying an oxidizer and purging the reactor; and supplying a reaction source containing nitrogen and purging the reactor.
