Claim Text:
1. A deposition device that deposits material particles, the deposition device comprising: a holding stage that holds a raw material for generating the material particles; an ionization section that ionizes the material particles utilizing a photoelectric effect in a reaction chamber to which the material particles are supplied; and an electrode section that guides the ionized material particles to a given area utilizing a Coulomb force, wherein the electrode section includes an electron trap electrode for trapping electrons released from the material particles due to the photoelectric effect, and a material particle trap electrode for trapping the ionized material particles; wherein the electron trap electrode has a cylindrical shape surrounding the holding stage, and the electron trap electrode produces the Coulomb force that guides the ionized material particles to the material particle trap electrode; wherein the electron trap electrode and the ionized material particles have the same polarity; and wherein the ionization section is configured to ionize the material particles by applying electromagnetic waves to the inside of the electron trap electrode having the cylindrical shape, the electromagnetic waves having an energy that is higher than a work function of the material particles.
