Abstract:
1. A film formation method for a semiconductor process for performing a film formation process to form a silicon-containing insulating film doped with a metal on a target substrate, in a process field, inside a process container configured to be selectively supplied with a silicon source gas and a metal source gas, the method comprising: forming a first insulating thin layer by use of a chemical reaction of the silicon source gas, while maintaining a shut-off state of supply of the metal source gas; then, forming a first metal thin layer by use of a chemical reaction of the metal source gas, while maintaining a shut-off state of supply of the silicon source gas; and then, forming a second insulating thin layer by use of the chemical reaction of the silicon source gas, while maintaining a shut-off state of supply of the metal source gas, so as to laminate the first insulating thin layer, the first metal thin layer, and the second insulating thin layer in this order, wherein the process field is configured to be selectively supplied with a NH each of said forming a first insulating thin layer and said forming a second insulating thin layer is arranged to cause the NH said forming a first metal thin layer is arranged to cause the NH
