摘要： An ion implanter including a time of flight energy measurement apparatus for measuring and controlling the energy of an ion beam includes an ion source for generating the ion beam, an ion acceleration assembly for accelerating the beam resulting in the beam comprising a series of ion pulses having a predetermined frequency and beam forming and directing structure for directing the ion beam at workpieces supported in an implantation chamber of the implanter. The time of flight energy measurement apparatus includes spaced apart first and second sensors, timing circuitry and conversion circuitry. The time of flight energy measurement apparatus measures an average kinetic energy of an ion included in a selected ion pulse of the ion beam. The first sensor and a second sensor are disposed adjacent the ion beam and spaced a predetermined distance apart, the second sensor being downstream of the first sensor. The first sensor generates a signal when an ion pulse of the ion beam passes the first sensor and the second sensor generates a signal when an ion pulse of the ion beam passes the second sensor. The timing circuitry of the energy measurement apparatus is electrically coupled to the first and second sensors and determines an elapsed time, t, for the selected ion pulse to traverse the predetermined distance between the first and second sensors. The timing circuitry calculates an average number of ion pulses, N, in the ion beam between the first and second sensors based on the approximation of the ion beam energy and calculates an offset time, t(offset), for the selected ion pulse using the formula, t(offset)=N.times.T. The timing circuitry than determines the elapsed time, t. The conversion circuitry converts the elapsed time, t, for the selected ion pulse into a measure of the energy of the ion beam.

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.

摘要： An architecture for a ribbon ion beam ion implanter system is disclosed. In one embodiment, the architecture includes an acceleration/deceleration parallelizing lens system for receiving a fanned ribbon ion beam and for at least parallelizing (and perhaps also accelerate or decelerate) the fanned ribbon ion beam into a substantially parallel ribbon ion beam, and an energy filter system downstream from the acceleration/deceleration parallelizing lens system and prior to a work piece to be implanted by the substantially parallel ribbon ion beam. The acceleration/deceleration parallelizing lens system includes lenses for at least parallelizing (and perhaps also accelerate or decelerate) the fanned ribbon ion beam and acceleration/deceleration lenses for accelerating or decelerating the substantially parallel ribbon ion beam. The parallelizing lens allows delivery of a high current ribbon ion beam to the work piece with energy that can extend down to as low as approximately 200 eV. The energy filter system provides a substantially parallel ribbon ion beam that is substantially free of energy contamination.
