Patent ID: 8410001

Claim:
A method of manufacturing a semiconductor device, comprising steps of: (a) supplying a source gas containing an element into a process vessel accommodating a substrate under a condition where a CVD reaction is caused to form a first layer including the element on the substrate; (b) supplying a carbon-containing gas into the process vessel to form a layer including a carbon on the first layer, thereby forming a second layer including the element and the carbon; (c) supplying the source gas containing the element into the process vessel under the condition where the CVD reaction is caused to additionally form a layer including the element on the second layer, thereby forming a third layer including the element and the carbon; (d) supplying a nitrogen-containing gas into the process vessel to nitride the third layer, thereby forming a carbonitride layer serving as a fourth layer including the element, the carbon and a nitrogen; and (e) performing a cycle including the steps (a) through (d) a predetermined number of times to form a carbonitride film having a predetermined thickness on the substrate.
