    Abstract: A grid assembly coupled to a discharge chamber of an ion beam source is configured for steering ion beamlets emitted from the discharge chamber at circularly asymmetrically determined steering angles. The grid assembly includes at least first and a second grid with a substantially circular pattern of holes, wherein each grid comprises holes positioned adjacent to one another. A plurality of the holes of the second grid is positioned with offsets relative to corresponding holes in the first grid. Due to the offsets in the holes in the second grid, ions passing through the offset holes are electrostatically attracted towards the closest circumferential portion of the downstream offset holes. Thus, the trajectories of ions passing through the offset holes are altered. The beamlet is steered by predetermined asymmetric angles. The predetermined steering angles are dependent upon the hole offsets, voltage applied to the grids, and the distance between the grids.

    Abstract: A method and system of location specific processing on a substrate is described. The method comprises establishing a gas cluster ion beam (GCIB) according to a set of beam properties and measuring metrology data for a substrate. Thereafter, the method comprises determining at least one spatial gradient of the metrology data at one or more locations on the substrate and adjusting at least one beam property in the set of beam properties for the GCIB according to the determined at least one spatial gradient. Using the metrology data and the adjusted set of beam properties, correction data for the substrate is computed. Following the computing, the adjusted GCIB is applied to the substrate according to the correction data.

    Abstract: In an ion implantation method, ion implantation into a substrate is performed while changing a relative positional relation between an ion beam and the substrate. A first ion implantation process in which a uniform dose amount distribution is formed within the substrate and a second ion implantation process in which a non-uniform dose amount distribution is formed within the substrate are performed in a predetermined order. Moreover, a cross-sectional size of an ion beam irradiated on the substrate during the second ion implantation process is set smaller than a cross-sectional size of an ion beam irradiated on the substrate during the first ion implantation process.

    Abstract: The invention relates to a blocking member to be placed in the diffraction plane of a TEM. It resembles the knife edge used for single sideband imaging, but blocks only electrons deflected over a small angle. As a result the Contrast Transfer Function of the TEM according to this invention will equal that of a single sideband microscope at low frequencies and that of a normal microscope for high frequencies. Preferable the highest frequency blocked by the blocking member is such that a microscope without the blocking member would show a CTF of 0.5.
