    Abstract: A gas distributor for an ion source includes a plate having a recess and a series of apertures spaced radially outward from the recess. The apertures define paths for the flow of a gas through the plate, and the gas distributor further includes a sacrificial element that is separate from the plate and that is receivable and seats within the recess. The sacrificial element forms an area of the gas distributor that is subjected to erosive forces during normal operations of the ion source, and therefore, prevents erosion of the surface of the plate. The sacrificial element is removable from the plate and replaceable with another sacrificial element during a procedure which neither requires the plate to be removed from the ion source nor the ion source to be disassembled.

    Abstract: A plurality of removable shields are disclosed for use with ion source in ion implanters. Specifically, the shields fit over the extraction electrode assembly, the sides of the interior walls and the cold-plate inside an ion source chamber. The shields are easily mountable and dismountable by the maintenance personnel. It is shown that shields can very effectively protect the insides of ion source from contamination by toxic materials emanating from the ionization source. A method is also disclosed for cleaning the shields outside the ion source by means of bead blasting followed by washing by deionized water and rinse with isopropyl alcohol. It is shown that the turn-around-time for preventive maintenance of an ion source in an ion implanter can be shortened by a factor of four.

    Abstract: A small fast atom beam source is capable of neutralizing ions at a high rate and of emitting a fast atom beam efficiently and with excellent directivity. A gas is introduced into the area between a plate-shaped anode having a plurality of atom emitting holes and a plate-shaped anode facing the cathode. A gas discharge is induced by a DC high-voltage power supply, thereby forming a plasma. Ions that are produced by the plasma are accelerated toward the cathode and neutralized in and near the atom emitting holes, which have lengths larger than the diameters thereof, thereby emitting a fast atom beam at a high rate of neutralization.

    Abstract: The present invention relates to an ion-optical system for a gas-discharge ion source, the system comprising a screen grid and an accelerator grid each constituted by a respective frame and a set of wires held parallel by supports and fixed to said frames by means of springs, the frames and the grids being assembled together by means of insulators to which they are fixed. According to the invention, the system further comprises a decelerator grid constituted by a frame and a set of wires, the frame of the decelerator grid being engaged in the frame of the accelerator grid and being separated therefrom by insulators. The supports of the wires are constituted either by a comb-shaped plate or by rollers with at least one of the rollers installed in the screen grid being shaped so as to be barrel-shaped, having a larger diameter in its center than at its ends. The pitch of the wires of the screen grid is preferably determined in such a manner as to ensure that the outermost beams converge towards the central beam by a predetermined amount.

    Abstract: Ion implantation equipment is modified so as to provide filament reflectors to a filament inside of an arc chamber, and to remove the electrical insulators for the filament outside of the arc chamber and providing a means of shielding, thereby reducing the formation of a conductive layer on said insulators and greatly extending the lifetime and reducing downtime of the equipment. The efficiency of the equipment is further enhanced by means of an interchangeable liner for the arc chamber that increases the wall temperature of the arc chamber and thus the electron temperature. The use of tungsten parts inside the arc chamber, obtained either by making the arc chamber itself or portions thereof of tungsten, particularly the front plate having the exit aperture for the ion beam, or by inserting a removable tungsten liner therein, decreases contamination of the ion beam. Serviceability of the arc chamber is improved by means of a unitary clamp that separately grips both the filament and filament reflectors. This clamp can also advantageously be made of tungsten.
