Patent ID: 7866578

Claim:
A film forming apparatus comprising: an aerosol generating section which generates an aerosol by dispersing particulate material in a carrier gas; a jetting nozzle having an internal passage which is formed in the jetting nozzle and through which the aerosol flows, the internal passage having one end defining a supply port which receives a supply of the aerosol from the aerosol generating section and having other end defining a jetting port from which the aerosol is jetted toward a process-objective material; a narrowed channel which is provided in the internal passage and which has a channel area narrower than a channel area on an upstream of the narrowed channel; a collision portion which is provided in the internal passage on a downstream of the narrowed channel, and against which a flow of the aerosol passed through the narrowed channel collides; an obstacle member; and a front end passage provided in the internal passage downstream from the collision portion, wherein the front end passage is in fluid communication with the jetting port, wherein the collision portion surrounds a portion of the obstacle member.
