    Abstract: An apparatus for ion implantation using high perveance beams is disclosed. The apparatus includes a dipole magnet apparatus that provides an adjustment to a cross-beam magnetic dipole field in an ion implantation system. Introduction and control of the magnetic dipole field gradient in a low energy implantation system as disclosed herein gives a significant improvement to the magnet's acceptance and beam focusing which largely defines the effective transported beam current. The apparatus involves the use of ferromagnetic yokes of a prescribed shape and a portion of a secondary magnet coil following along the outside radius of a set of primary dipole magnet coils which define and delineate the primary magnetic field area and beam path. The current return path for the secondary magnet coil is via another portion of the secondary magnet coil that follows a path such that the field generated by the return path secondary magnet coil is orthogonal to the primary magnetic field. The resulting magnetic field across the beam cross-section has a sloping shape with relative maxima and minima near the transverse beamline boundary. The action of the magnetic field distribution on the ion beam acts to compensate the space-charge dispersion of high perveance beams.

    Abstract: An improved ion beam neutralizer (22) is provided for neutralizing the electrical charge of an ion beam (28) output from an extraction aperture (50). The neutralizer comprises a source of water (52); a vaporizer (54) connected to the source of water; a mass flow controller (56) connected to the vaporizer; and an inlet (60) connected to the mass flow controller. The vaporizer (54) converts water from the source (52) from a liquid state to a vapor state. The mass flow controller (56) receives water vapor from the vaporizer (54) and meters the volume of water vapor output by a mass flow controller outlet (66). The inlet (60) is provided with an injection port (68) located proximate the ion beam extraction aperture (50) and receives the metered volume from the outlet (66). The injection port (68) is positioned near the extraction aperture so that the ion beam and the water vapor interact to neutralize the ion beam. The improved ion beam neutralizer (22) is especially effective in low energy (less than ten kilo-electron volts (10 KeV)) beam applications.

    Abstract: A method for doping a semiconductor substrate is disclosed wherein a layer of a first conductivity type is first formed followed by forming a blocking layer with an open area. An etch process is performed through the open area to remove the layer of the first conductivity type to exposed the top surface of the semiconductor substrate. Dopant ions are introduced to form a dopant region of a second conductivity type on the beneath the top surface of the semiconductor substrate wherein the dopant region of the second conductivity type is not in contact with the dopant layer of the first conductivity type that is not etched off thus forming a PN structure to form diodes for the interdigitated back contact photovoltaic cells. Since the ion doping processes are self-aligned, the mask requirements are minimized and the production cost for solar cells are reduced.
