Abstract:
1. A method of manufacturing a semiconductor integrated circuit device provided with a memory cell having an information storing capacitor formed above a semiconductor substrate, wherein the information storing capacitor has a lower electrode, an upper electrode, and an insulating film disposed between the lower electrode and the upper electrode, the insulating film comprises a first element, a second element, and oxygen, the insulating film is deposited by a method of alternately exposing a first precursor as a compound containing the first element, a second precursor as a compound containing the second element and an oxidant containing oxygen to a deposition surface, and an adsorption ratio of the first precursor to a plurality of adsorption sites on the deposition surface is less than 100% in the step of exposing the first precursor to the deposition surface, leaving remaining adsorption sites for the second precursor and the second precursor is adsorbed to the remaining adsorption sites for the second precursor in the step of exposing the second precursor to the deposition surface.
