摘要： A method and structure are described for preventing the accidental introduction of gasoline into the fuel system of a diesel-powered vehicle. In a first preferred embodiment, a gasoline fuel nozzle is configured with a magnet, such as magnetic strips, and the entrance to a fill tube of a diesel-powered is configured with a magnetic field sensor ring. When an incorrect fueling operation, such as the introduction of gasoline into the fuel tank of the diesel-powered vehicle, is attempted the sensor ring alerts the operator visually and/or audibly before fueling starts, thereby preventing incorrect fueling. In alternative embodiments, sensing of an attempted incorrect fueling operation may require only the sensor ring.

摘要： A split grid multi-channel secondary particle detector for a charged particle beam system includes a first grid segment and a second grid segment, each having independent bias voltages creating an electric field such that the on-axis secondary particles that are emitted from the target are directed to one of the grids. The bias voltages of the grids can be changed or reversed so that each grid can be used to detect the secondary particles and the multi-channel particle detector as a whole can extend its lifetime.

摘要： A direct-write electron beam lithography system employing a patterned beam-defining aperture to enable the generation of high current-density shaped beams without the need for multiple beam-shaping apertures, lenses and deflectors is disclosed. Beam blanking is accomplished without the need for an intermediate crossover between the electron source and the wafer being patterned by means of a double-deflection blanker, which also facilitates proximity effect correction. A simple type of “moving lens” is utilized to eliminate off-axis aberrations in the shaped beam. A method for designing the patterned beam-defining aperture is also disclosed.

摘要： A charged particle optical system for testing, imaging or inspecting substrates comprises: a charged particle optical assembly configured to produce a line of charged particle beams equally spaced along a main scan axis, each beam being deflectable through a large angle along the main scan axis; and linear detector optics aligned along the main scan axis. The detector optics includes a linear secondary electron detector, a field free tube, voltage contrast plates and a linear backscattered electron detector. The large beam deflection is achieved using an electrostatic deflector for which the exit aperture is larger than the entrance aperture. One embodiment of the deflector includes: two parallel plates with chamfered inner surfaces disposed perpendicularly to the main scan axis; and a multiplicity of electrodes positioned peripherally in the gap between the plates, the electrodes being configured to maintain a uniform electric field transverse to the main scan axis.

The electron beam column comprises an electron gun, an accelerating region, scanning deflectors, focusing lenses, secondary electron detectors and an asymmetrical detector optics assembly. The detector optics assembly comprises a field-free tube, asymmetrical with respect to the electron optical axis; the asymmetry can be introduced by offsetting the field-free tube from the electron optical axis or by chamfering the end of the tube. In other embodiments the detector optics assembly comprises a field-free tube and a voltage contrast plate, either or both of which are asymmetrical with respect to the electron optical axis.

摘要： A proximity effect correction method for electron beam lithography suitable for use in a raster scan system. The exposure pattern consists of shapes; these shapes are subdivided into edge pixels and interior pixels; the pattern is then modified by uniformly removing a fraction of the interior pixels. The method reduces the backscattered electron background dose, improving the contrast for shapes with fine features, particularly when they are in close proximity to large or densely packed shapes.

摘要： A charged particle shaped beam column includes: an objective lens configured to form a charged particle shaped beam on the surface of a substrate, wherein the disk of least confusion of the objective lens does not coincide with the surface of the substrate; an optical element with 8N poles disposed radially symmetrically about the optic axis of the column, the optical element being positioned between a condenser lens and the objective lens, wherein integer N1; and a power supply applying excitations to the optical element's 8N poles to provide an octupole electromagnetic field. The octupole electromagnetic field induces azimuthally-varying third-order deflections to beam trajectories passing through the 8N-pole optical element. By controlling the excitation of the 8N poles a shaped beam, such as a square beam, can be formed at the surface of the substrate.
