Abstract

A film forming apparatus by which uniform and large area films can be formed according to the AD method. The film forming apparatus includes: a film forming chamber; a substrate holder located in the film forming chamber, for holding a substrate on which a structure is to be formed; an exhaust pump for exhausting an interior of the film forming chamber; an aerosol generating unit for generating an aerosol by blowing up a raw material powder placed in a container with a gas; a carrier pipe for introducing the generated aerosol into the film forming chamber; a nozzle for spraying the aerosol introduced via the carrier pipe toward the substrate; and a control unit for chaotically changing a relative position of the substrate held by the substrate holder and the nozzle.
