Patent attributes
A film forming apparatus includes an aerosol generating section which generates an aerosol; a jetting nozzle having an internal passage formed therein and through which the aerosol flows, the internal passage having one end serving as a supply port of the aerosol and having other end serving as a jetting port of the aerosol; 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; and 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. Since the aggregated particles are crushed and supplied from the jetting nozzle in the form of fine particles, a thin and uniform film can be formed on the process-objective material.
