  • Patent number: 8835882
    Abstract: The invention provides a method to real time monitor the ion beam. Initially, turn on an ion implanter which has a wafer holder, a Faraday cup and a measurement device positioned close to a special portion of a pre-determined ion beam path of the ion beam, wherein the Faraday cup is positioned downstream the wafer holder and the measurement device is positioned upstream the wafer holder. Then, measure a first ion beam current received by the Faraday cup and a second ion beam current received by the measurement device. By continuously measuring the first and second ion beam current, the ion beam is real-time monitored even the Faraday cup is at least partially blocked during the period of moving the wafer holder across the ion beam. Accordingly, the on-going implantation process and the operation of the implanter can be adjusted.

  • Publication number: 20140212595
    Abstract: The time-averaged ion beam profile of an ion beam for implanting ions on a work piece may be smoothed to reduce noise, spikes, peaks, and the like and to improve dosage uniformity. Auxiliary magnetic field devices, such as electromagnets, may be located along an ion beam path and may be driven by periodic signals to generate a fluctuating magnetic field to smooth the ion beam profile (i.e., beam current density profile). The auxiliary magnetic field devices may be positioned outside the width and height of the ion beam, and may generate a non-uniform fluctuating magnetic field that may be strongest near the center of the ion beam where the highest concentration of ions may be positioned. The fluctuating magnetic field may cause the beam profile shape to change continuously, thereby averaging out noise over time.

  • Publication number: 20140161987
    Abstract: A variable aperture within an aperture device is used to shape the ion beam before the substrate is implanted by shaped ion beam, especially to finally shape the ion beam in a position right in front of the substrate. Hence, different portions of a substrate, or different substrates, can be implanted respectively by different shaped ion beams without going through using multiple fixed apertures or retuning the ion beam each time. In other words, different implantations may be achieved respectively by customized ion beams without high cost (use multiple fixed aperture devices) and complex operation (retuning the ion beam each time). Moreover, the beam tune process for acquiring a specific ion beam to be implanted may be accelerated, to be faster than using multiple fixed aperture(s) and/or retuning the ion beam each time, because the adjustment of the variable aperture may be achieved simply by mechanical operation.

  • Publication number: 20140151572
    Abstract: A gas mixture method and apparatus of prolonging lifetime of an ion source for generating an ion beam particularly an ion beam containing carbon is proposed here. By mixing the dopant gas and the minor gas together to generate an ion beam, undesired reaction between the gas species and the ion source can be mitigated and thus lifetime of the ion source can be prolonged. Accordingly, quality of ion beam can be maintained.

  • Patent number: 8653807
    Abstract: Techniques for ion beam current measurement, especially for measuring low energy ion beam current, are disclosed. In one exemplary embodiment, the techniques may be realized as an ion beam current measurement apparatus has at least a planar Faraday cup and a magnet device. The planar Faraday cup is close to an inner surface of a chamber wall, and may be non-parallel to or parallel to the inner surface. The magnet device is located close to the planar Faraday cup. Therefore, by properly adjusting the magnetic field, secondary electrons, incoming electrons and low energy ions may be adequately suppressed. Further, the planar Faraday cup may surround an opening of an additional Faraday cup being any conventional Faraday cup. Therefore, the whole ion beam may be received and measured well by the larger cross-section area of at least the planar Faraday cup on the ion beam path.

  • Patent number: 8581217
    Abstract: A method capable of monitoring ion implantation. First, an ion beam and a workpiece are provided. Next, implant the workpiece by the ion beam and generate a profile having numerous signals relevant to respectively numerous relative positions between the ion beam and the workpiece, wherein the profile has at least a higher portion, a gradual portion and a lower portion. Therefore, by directly analyzing the profile without referring to a pre-determined profile and without using a profiler measuring the ion beam, some ion beam information may be acquired, such as beam height, beam width, ion beam current distribution on the ion beam cross-section, and so on, and the ion implantation may be monitored real-timely. Furthermore, when numerous workpieces are implanted in sequence, the profile(s) of one or more initially implanted workpiece(s) may be to generate a reference for calibrating the ion implantation of the following workpieces.
