    摘要: The present invention discloses a system and method for generating gas cluster ion beams (GCIB) having very low metallic contaminants. Gas cluster ion beam systems are plagued by high metallic contamination, thereby affecting their utility in many applications. This contamination is caused by the use of thermionic sources, which impart contaminants and are also susceptible to short lifecycles due to their elevated operating temperatures. While earlier modifications have focused on isolating the filament from the source gas cluster as much as possible, the present invention represents a significant advancement by eliminating the thermionic source completely. In the preferred embodiment, an inductively coupled plasma and ionization region replaces the thermionic source and ionizer of the prior art. Through the use of RF or microwave frequency electromagnetic waves, plasma can be created in the absence of a filament, thereby eliminating a major contributor of metallic contaminants.

    摘要: The present invention comprises a method for high tilt angle implantation, with angular precision not previously achievable. An ion beam, having a width and height dimension, is made up of a number of individual beamlets. These beamlets typically display a higher degree of parallelism in one of these two dimensions. Thus, to minimize angular error, the workpiece is tilted about an axis substantially perpendicular to the dimension having the higher degree of parallelism. The workpiece is then implanted at a high tilt angle and rotated about a line orthogonal to the surface of the workpiece. This process can be repeated until the high tilt implantation has been performed in all required regions.

    摘要: An architecture (100) for a ribbon ion beam ion implanter system (102) is disclosed. In one embodiment, the architecture (100) includes an acceleration/deceleration parallelizing lens system (120) for receiving a fanned ribbon ion beam (124) and for at least parallelizing (and perhaps also accelerate or decelerate) the fanned ribbon ion beam (124) into a substantially parallel ribbon ion beam (112), and an energy filter system (122) downstream from the acceleration/deceleration parallelizing lens system (120) and prior to a work piece (128) to be implanted by the substantially parallel ribbon ion beam. The acceleration/deceleration parallelizing lens system (120) includes lenses (126) for at least parallelizing (and perhaps also accelerate or decelerate) the fanned ribbon ion beam (124) and acceleration/deceleration lenses for accelerating or decelerating the substantially parallel ribbon ion beam (112). The parallelizing lens allows delivery of a high current ribbon ion beam to the work piece (128) with energy that can extend down to as low as approximately 200 eV.

    摘要: The present invention employs a mass analyzer comprised of a pair of permanent magnets to select a desired species from multiple species within a ribbon type ion beam. These permanent magnets provide a substantially uniform magnetic field of adequate magnitude in a small region not attainable with electromagnets that applies a specific force in a desired direction. The force is applied to passing particles of a ribbon ion beam and causes paths of the particles to alter according to their respective mass. As a result, a selected species can be obtained from a beam by the force causing rejected species and/or contaminants to fail passing through the mass analyzer (e.g., by impacting the magnets themselves and/or another barrier present in the analyzer). As a result of the mass analyzer, dopant/species sources that generate multiple species can be employed instead of sources that only supply a single dopant/species.

    摘要: Apparatus and method for modifying an object with electrons are provided, by which the object can be uniformly and efficiently modified with the electrons under a pressure substantially equal to atmospheric pressure even when having a relatively wide surface area to be treated. This method uses a cold-cathode electron emitter having the capability of emitting electrons from a planar electron emitting portion according to tunnel effect, and preferably comprising a pair of electrodes, and a strong field drift layer including nanocrystalline silicon disposed between the electrodes. The object is exposed to electrons emitted from the planar electron emitting portion by applying a voltage between the electrodes. It is preferred that an energy of the emitted electrons is selected from a range of 1 eV to 50 keV, and preferably 1 eV to 100 eV.
