Abstract:
1. A film forming apparatus comprising: a film forming chamber which forms a film; a jetting mechanism which jets aerosol containing material particles onto a substrate in the film forming chamber to form a film formed of the material particles on the substrate; a measuring chamber communicating with the film forming chamber; a measuring mechanism which measures a thickness of the film in the measuring chamber; a pressure adjusting mechanism which is connected to the film forming chamber and the measuring chamber via a first valve and a second valve, respectively, and which controls an internal pressure of the film forming chamber and an internal pressure of the measuring chamber; a conveyor which transports the substrate between the film forming chamber and the measuring chamber; a blocking section which blocks a communication between the film forming chamber and the measuring chamber; a pressure controller which controls the pressure adjusting mechanism and the valves; and a blocking controller which controls the blocking section, wherein, when the substrate is transported by the conveyor, the blocking controller controls the blocking section to communicate the film forming chamber and the measuring chamber, and the pressure controller closes the second valve between the pressure adjusting mechanism and the measuring chamber, opens the first valve between the pressure adjusting mechanism and the film forming chamber, and controls the pressure adjusting mechanism to make the internal pressure of the measuring chamber greater than the internal pressure of the film forming chamber.
