Abstract:
An apparatus for forming a film of ultra-fine particles comprising:(A) an aerosol generating apparatus in which ultra-fine particles of smaller than 0.1 .mu.m in diameter are made from evaporated material, and are dispersed and floating in gas;(B) a holding mechanism for holding a base body having a hole with a bottom or through hole, said hole or said through hole formed therein with a diameter smaller than 2 .mu.m and an aspect ratio of larger than one, or a groove formed therein with a width smaller than 2 .mu.m and a ratio of depth/width larger than one, a film of ultra-fine particles being formed on said base body;(C) a heating mechanism for heating said base body;(D) a pressure-adjusting mechanism for maintaining said aerosol at a predetermined pressure;(E) a film forming container containing at least said holding mechanism; and(F) a vacuum system connected to said film forming container.
