Abstract:
1. A method of manufacturing a semiconductor device, comprising: (a) providing a zirconium source having zirconium, carbon and nitrogen onto a semiconductor substrate to form an adsorption layer of the zirconium source on the semiconductor substrate; (b) performing a first purging process to remove a non-adsorbed portion of the zirconium source from the semiconductor substrate; (c) providing an oxidizing gas onto the adsorption layer of the zirconium source to form an oxidized adsorption layer of the zirconium source on the semiconductor substrate; (d) performing a second purging process to remove a non-reacted portion of the oxidizing gas; (e) providing a nitriding gas on the oxidized adsorption layer of the zirconium source to form a zirconium carbo-oxynitride layer on the semiconductor substrate; and (f) performing a third purging process to remove a non-reacted portion of the nitriding gas, wherein the steps from (a) through (f) are repeated in a cycle to form a dielectric layer of zirconium carbo-oxynitride on the semiconductor substrate, and wherein the dielectric layer is formed to have a plurality of atomic layers of zirconium carbo-oxynitride having a chemical formula of ZrO
