    摘要: The disclosure provides a hybrid magnet structure which includes two dipole magnets assemblies arranged oppositely, and each dipole magnet assembly includes a permanent magnet, two iron cores, and a moveable magnetic field shunt element. The hybrid magnet structure is adapted to focus particle beams of different positions by applying an adjustable gradient magnetic field in the horizontal or vertical direction of the particle beam. By passing the charged particle beams through the gradient magnetic field established between the two dipole magnets, the aspect of focusing the charged particle beam is achieved. In addition, the intensity of the gradient magnetic field can be altered by adjusting the gap between the movable magnetic field shunt element and the permanent magnet, thereby controlling the particle beam size on a specific axis for different energies or masses of the charge particles.

    摘要: Ion implantation systems and processes are disclosed. An exemplary ion implantation system may include an ion source, an extraction manipulator, a magnetic analyzer, and an electrode assembly. The extraction manipulator may be configured to generate an ion beam by extracting ions from the ion source. A cross-section of the generated ion beam may have a long dimension and a short dimension orthogonal to the long dimension of the ion beam. The magnetic analyzer may be configured to focus the ion beam in an x-direction parallel to the short dimension of the ion beam. The electrode assembly may be configured to accelerate or decelerate the ion beam. One or more entrance electrodes of the electrode assembly may define a first opening and the electrode assembly may be positioned relative to the magnetic analyzer such that the ion beam converges in the x-direction as the ion beam enters through the first opening.

    摘要: 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.

    摘要: 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.

    摘要: In plasma doping a non-planar semiconductor device, a substrate having a non-planar semiconductor body formed thereon is obtained. The substrate having the non-planar semiconductor body may be placed into a chamber. A plasma may be formed in the chamber and the plasma may contain dopant ions. A first bias voltage may be generated to implant dopant ions into a region of the non-planar semiconductor body. A second bias voltage may be generated to implant dopant ions into the same region. In one example, the first bias voltage and the second bias voltage may be different.
