Patent ID: 7829154

Claim:
A particle deposition apparatus for depositing particles on a deposited body by using a solution, with particles dispersed in a solvent, as a source material, comprising: a solution supply device that supplies the source material; a charging device that electrically charges the source material; a vacuum chamber into which the source material jetted from the solution supply device can be introduced through a jet nozzle, the vacuum chamber having a vacuum chamber evacuation port for setting a pressure inside the vacuum chamber to a pressure lower than atmospheric pressure; and a deposition chamber, which is adjoined to the vacuum chamber, into which the source material emitted from the vacuum chamber can be introduced through a skimmer nozzle, the deposition chamber having a deposition chamber evacuation port for setting a pressure inside of the deposition chamber to a pressure that is lower than the pressure inside the vacuum chamber, and a separation device that selects only particles having a particular mass-to-charge ratio from the source material and deposits the selected particles on the deposited body; wherein the pressure inside the deposition chamber is less than the pressure inside the vacuum chamber, and the pressure inside the vacuum chamber is less than atmospheric pressure.
