    摘要: A method of tailoring the dopant profile of a workpiece by modulating one or more operating parameters is disclosed. In one embodiment, the workpiece may be a solar cell and the desired dopant profile may include a heavily doped surface region and a highly doped region. These two regions can be generated by varying one or more of the parameters of the ion implanter. For example, the extraction voltage may be changed to affect the energy of the implanted ions. The ionization energy can be changed to affect the species of ions being generated from the source gas. In another embodiment, the source gasses that are ionized may be changed to affect the species being generated. After the implant has been performed, thermal processing is performed which minimizes the diffusion of the ions in the workpiece.

    摘要: A method of implanting a workpiece in an ion implantation system. The method may include providing an extraction plate adjacent to a plasma chamber containing a plasma, such that the extraction plate extracts ions from the plasma through at least one aperture that provides an ion beam having ions distributed over a range of an angles of incidence on the workpiece. The method may include scanning the workpiece with respect to the extraction plate and varying a power level of the plasma during the scanning from a first power level to a second power level, wherein at a surface of the workpiece, a first beam width at a first power level is greater than a second beam width at a second power level.

    摘要: A mask or set of masks is disclosed in which outward projections are placed on either side of at least one aperture. An ion beam is then directed through the mask toward a workpiece. An ion collecting device or an optical system is then used to measure the alignment of the mask to the ion beam. These projections serve to increase the sensitivity of the system to misalignment. In another embodiment, a blocker is used to create a region of the workpiece that is not subjected to a blanket implant. This facilitates the use of optical means to insure and determine alignment of the mask to the ion beam.
