Abstract:
1. A film forming apparatus comprising: a substrate holding plate configured to hold a substrate to be processed; a process chamber that defines a process space with the substrate holding plate; an exhaust path configured to exhaust the process space from an upper outside of an outer periphery of the substrate; and a process gas supply channel provided above the substrate holding plate to face the substrate holding plate and configured to supply a process gas containing a raw gas and a carrier gas to the process space, wherein the process gas supply channel, when the substrate holding plate is viewed from a vertical direction, includes a process gas introduce opening provided at a center portion of the process chamber to introduce the process gas in the process space; a process gas blocking member provided between the process gas introduce opening and the substrate holding plate, to block a direct pass of the process gas to an inside of the outer periphery of the substrate; and a process gas discharge opening provided at a periphery of the process gas blocking member to flow the process gas into the outside of the outer periphery of the substrate to the exhaust path in the process space and to not flow the process gas directly into the inside of the outer periphery of the substrate.
