Abstract:
A gas supply apparatus that supplies a process gas to a reaction chamber, comprising:a base;manifold blocks mounted on said base along a gas supply flow path and spaced apart from one another, each of said manifold blocks having an internal gas supply flow path;one of said manifold blocks being connectable to a gas supply source and another of said manifold blocks being connectable to a reaction chamber;a mass flow controller mounted on adjacent ones of said manifold blocks;upstream and downstream operating valves adjacent said mass flow controller mounted on said manifold blocks for controlling gas flow along said gas flow path;a filter mounted on said manifold blocks for filtering gas that flows along said gas flow path;said mass flow controller having a connector for receiving signal transmission that is disposed in a region between said adjacent manifold blocks on which said mass flow controller is mounted.
