    Abstract: An ion source for use in a radiation generator tube includes a back passive cathode electrode, a passive anode electrode downstream of the back passive cathode electrode, a magnet adjacent the anode, and a front passive cathode electrode downstream of the passive anode electrode. The front passive cathode electrode and the back passive cathode electrode define an ionization region therebetween. At least one field emitter array (FEA) cathode is configured to electrostatically discharge due to an electric field in the ion source. The back passive cathode electrode and the passive anode electrode, and the front passive cathode electrode and the passive anode electrode, have respective voltage differences therebetween, and the magnet generating a magnetic field, such that a Penning-type trap is produced to confine electrons from the electrostatic discharge to the ionization region. At least some of the electrons in the ionization region interact with an ionizable gas to create ions.

    Abstract: A method of controlling operation of an indirectly-heated cathode (IHC) ion source includes a step of measuring a rate of loss of cathode weight of the IHC ion source that occurs during operation using a first cathode configuration and under a first set of operation conditions. A maximum weight loss for the first cathode configuration is determined, and a cathode lifetime is calculated based upon the rate of cathode weight loss and the maximum weight loss. A further method includes receiving a minimum source bias power value for operation of a cathode in a first configuration, measuring a rate of decrease in source bias power for a cathode in the first configuration, and calculating a lifetime of the cathode based upon the minimum source bias power and rate of decrease in source bias power.

    Abstract: A focused ion beam (FIB) system is disclosed, comprising an inductively coupled plasma ion source, an insulating plasma chamber containing the plasma, a conducting source biasing electrode in contact with the plasma and biased to a high voltage to control the ion beam energy at a sample, and a plurality of apertures. The plasma within the plasma chamber serves as a virtual source for an ion column comprising one or more lenses which form a focused ion beam on the surface of a sample to be imaged and/or FIB-processed. The plasma is initiated by a plasma igniter mounted near or at the column which induces a high voltage oscillatory pulse on the source biasing electrode. By mounting the plasma igniter near the column, capacitive effects of the cable connecting the source biasing electrode to the biasing power supply are minimized. Ion beam sputtering of the apertures is minimized by proper aperture materials selection.

    Abstract: A method of manufacturing a semiconductor device includes the steps of: providing a supply of molecules containing a plurality of dopant atoms into an ionization chamber, ionizing said molecules into dopant cluster ions, extracting and accelerating the dopant cluster ions with an electric field, selecting the desired cluster ions by mass analysis, modifying the final implant energy of the cluster ion through post-analysis ion optics, and implanting the dopant cluster ions into a semiconductor substrate. In general, dopant molecules contain n dopant atoms, where n is an integer number greater than 10. This method enables increasing the dopant dose rate to n times the implantation current with an equivalent per dopant atom energy of 1/n times the cluster implantation energy, while reducing the charge per dopant atom by the factor n.
