摘要： A power supply system for an ion implantation system. In one particular exemplary embodiment, the system may be realized as a power supply system that includes a low frequency power inverter, a stack driver and a high voltage power generation unit that receives source power from the power inverter. The high voltage generation unit may include a high voltage transformer for providing an output power that is multiplied to a desired output level and delivered to an input terminal of an ion beam accelerator. The power supply system may also include a dielectric enclosure that encases at least a portion of the high voltage power generation unit, thereby preventing variation in the break down strength of the internal components.

摘要： An ion implanter includes a source of a stationary, planar ion beam, a set of beamline components that steer the ion beam along a normal beam path as determined by first operating parameter values, an end station that mechanically scans the wafer across the normal beam path, and control circuitry that responds to a glitch in the ion beam during implantation pass to (1) immediately alter an operating parameter of at least one of the beamline components to a second value to direct the ion beam away from the normal beam path and thereby cease implantation at an implantation transition location on the wafer, (2) subsequently move the wafer to an implantation-resuming position in which the implantation transition location on the wafer lies directly on the normal path of the ion beam, and (3) return the operating parameter to its first value to direct the ion beam along the normal beam path and resume ion implantation at the implantation transition location on the wafer. The operating parameter may be an output voltage of an extraction power supply, or other voltages and/or currents of beamline components that affect the path of the ion beam.

摘要： An ion implanter has a source arc chamber including a conductive end wall at a repeller end of the arc chamber, the end wall having a central portion surrounding an opening. A ceramic insulator is secured to an outer surface of the end wall, such as by peripheral screw threads engaging mating threads at the periphery of a recessed area of the end wall. A conductive repeller has a narrow shaft secured to the insulator and extending through the end wall opening, and a body disposed within the source arc chamber adjacent to the end wall. The end wall, insulator and repeller are configured to form a continuous vacuum gap between the central portion of the end wall and (i) the repeller body, (ii) the repeller shaft, and (iii) the insulator. The insulator interior surface can have a ridged cross section.

摘要： A system, method and program product for determining contamination of an ion beam are disclosed. In the event of an isobaric interference, or near isobaric interference between a contaminant ion and an expected ion of an ion beam, which is difficult to detect, it is possible to measure a third ion in the ion beam and estimate, based on the amount of the third ion measured, a relative amount of the contaminant ion compared to the expected ion. The estimated relative amount of the contaminant ion is used together with a measured mass resolution of the ion implantation system to determine whether an ion implantation process needs to be suspended.

摘要： Methods of ion implantation and ion sources used for the same are provided. The methods involve generating ions from a source feed gas that comprises multiple elements. For example, the source feed gas may comprise boron and at least two other elements (e.g., XaBbYc). The use of such source feed gases can lead to a number of advantages over certain conventional processes including enabling use of higher implant energies and beam currents when forming implanted regions having ultra-shallow junction depths. Also, in certain embodiments, the composition of the source feed gas may be selected to be thermally stable at relatively high temperatures (e.g., greater than 350° C.) which allows use of such gases in many conventional ion sources (e.g., indirectly heated cathode (IHC), Bernas) which generate such temperatures during use.
