    摘要: Apparatus and method for monitoring wafer charges are proposed. A conductive pin, a conductive spring and a conductive line are configured in series to connect the backside surface of the wafer and the sample conductor so that the backside surface of the wafer and the surface of the sample conductor have identical charge density. Hence, by using a static electricity sensor positioned close to the surface of the sample conductor, the charges on the wafer may be monitored. Note that the charges appeared on the frontside surface of the wafer induces charges on the backside surface of the wafer. As usual, the sample conductor is a sheet conductor and properly insulated from the surrounding environment. As usual, the sample conductor and the static electricity sensor are positioned outside the chamber where the wafer is placed and processed, so as to simplify the apparatus inside the chamber and reduce the contamination risk.

    摘要: A method for an ion implantation is provided. First, a non-parallel ion beam is provided. Thereafter, a relative motion between a workpiece and the non-parallel ion beam, so as to enable each region of the workpiece to be implanted by different portions of the non-parallel ion beam successively. Particularly, when at least one three-dimensional structure is located on the upper surface of the workpiece, both the top surface and the side surface of the three-dimensional structure may be implanted properly by the non-parallel ion beam when the workpiece is moved across the non-parallel ion beam one and only one times. Herein, the non-parallel ion beam can be a divergent ion beam or a convergent ion beam (both may be viewed as the integrated divergent beam), also can be generated directly from an ion source or is modified from a parallel ion beam, a divergent ion beam or a convergent ion beam.

    摘要: Techniques for measuring ion beam current, especially for measuring low energy ion beam current, are disclosed. The technique may be realized as an ion beam current measurement apparatus having at least a planar Faraday cup and a voltage assembly. The planar Faraday cup is located close to an inner surface of a chamber wall, and intersects an ion beam path. The voltage assembly is located outside a chamber having the chamber wall. Therefore, by properly adjusting the electric voltage applied on the planar Faraday cup by the voltage assembly, some undesired charged particles may be adequately suppressed. Further, the planar Faraday cup may surround an opening of a non-planar Faraday cup which may be any conventional Faraday cup. Therefore, the whole ion beam may be received and measured well by the larger cross-section area of the planar Faraday cup on the ion beam path.

A second voltage may be applied across the electrode assembly. The ion beam may enter the electrode assembly at the first energy, exit the electrode assembly at a third energy, and implants ions into the target at the third energy. The third energy may be different from the second energy.
