Abstract:
Metallic ion source for resolving the issue of not being able to produce high-density ions efficiently with small-scale ion sources in situations where an electron beam injecting scheme is employed as the evaporation source to evaporate a solid, and for producing high-density ions highly efficiently. Designed to be compact and lightweight, the metallic ion source also facilitates selection of the ion extraction direction. The ion source, structured exploiting the characteristic physical property that whether ionization takes place is dependent on the energy of the electron beam, is furnished with a dual evaporation-plasma chamber that inside the same chamber enables a high-speed electron beam, whose ionization efficiency is low, and low-speed electrons generated by electric discharge, whose ionization efficiency is high, to participate independently and simultaneously in, respectively, evaporation of precursor and ionization action.
Abstract:
An ion source has an arc chamber having an arc chamber body. An electrode extends into an interior region of the arc chamber body, and a cathode shield has a body that is cylindrical having an axial hole. The axial hole is configured to pass the electrode therethrough. First and second ends of the body have respective first and second gas conductance limiters. The first gas conductance limiter extends from an outer diameter of the body and has a U-shaped lip. The second gas conductance limiter has a recess for a seal to protect the seal from corrosive gases and maintain an integrity of the seal. A gas source introduces a gas to the arc chamber body. A liner has an opening configured to pass the cathode shield therethrough, where the liner has a recess. A gap is defined between the U-shaped lip and the liner, wherein the U-shaped lip reduces a conductance of gas into the gap and the recess further reduces conductance of gas into the region.
Abstract:
A vacuum is maintained inside a vacuum partition (1). The whole of the solid packed container (3) is disposed inside the vacuum partition (1). A heater (7) sublimates the aluminum chloride (8) packed in lid packed container (3) to generate an aluminum chloride gas (9). An arc chamber (6) ionizes the aluminum chloride gas (9) and emits an ion beam (11) of the ionized aluminum chloride gas (9). A gas supply nozzle (10) leads the aluminum oride gas (9) from the solid packed container (3) into the arc chamber (6). A supporting part (4) supports and fixes the solid packed container (3) on the vacuum partition (1). A thermal conductivity of the supporting part (4) is lower than thermal conductivities of the vacuum partition (1) and the solid packed container (3).

Abstract:
An ion source includes an ion source chamber, a cathode disposed within the ion source chamber and configured to emit electrons to generate an arc plasma, and a repeller configured to repell electrons back into the arc plasma. The ion source chamber and cathode may comprise a refractory metal. The ion source chamber further includes a gas source configured to provide a halogen species to the ion source chamber. The reactive insert is interoperative with the halogen species to yield a first etch rate of the refractory metal material within the ion source chamber under a first set of operating conditions that is less than a second etch rate of the refractory metal material within the ion source chamber under the first set of operating conditions when the reactive insert is not disposed within the ion source chamber.

Abstract:
In an ion generator, a flexible discharge electrode 44 composed of one wire is provided to a base 43, and a turning motion of a free end 44b of the discharge electrode 44 about a fixed end 44a of the discharge electrode 44 is performed by repulsive force of a corona discharge generated by supplying a high voltage to the fixed end 44a. Therefore, in comparison with a discharge electrode composed of a bundle of thin wires, it is possible to significantly reduce dust emission from the free end 44b of the discharge electrode 44, and to further improve the ion generator 30 in maintenance interval. Since the discharge electrode 44 is compose of one wire, it is possible to reduce the discharge electrode 44 in size, easily observe the state of the discharge electrode 44, and simplify its maintenance. Since the discharge electrode 44 performs a turning motion, it is possible to transport the generated air ions EI to a wide area of a packaging film 10, and to enhance ionizing efficiency.
