    Abstract: A charged-particle beam system has a demagnifying lens for reducing the dimensions of an electron beam produced from an electron beam source, an objective lens for focusing the demagnified beam onto the surface of a target, a first deflector located before the demagnifying lens, a second deflector placed such that the deflection field produced by it is totally or partially superimposed on the objective lens field, and a third deflector located in a stage following the second deflector. An image of the light source is created by the demagnifying lens. An image of the light source image is formed on the target by the objective lens.

    Abstract: A slit lens arrangement for particle beams, and particularly for the projection of a mask onto a workpiece, includes a combined lens, having a cylinder lens and a quadrupole lens, the optical axes of which run parallel to each other, so that the optical axis of the quadrupole lens may be displaced in a parallel manner and which may have a gap-like opening between the pole shoes or in the electrodes with the same spatial relationship to each other. Both lenses are thus so arranged relative to each other, that the focussing of the quadrupole lens occurs in that plane in which the cylinder lens is not focussed, and the defocusing of the quadrupole lens occurs in that plane in which the cylinder lens focuses. Two combined lenses are provided with functionally identical elements arranged such that the optical axes of both lenses lie coaxial to each other, defining the mid-axis of the total system and in which the beam path is telescopic throughout the entire slit lens arrangement. The optical axis of the image is given by the optical axis of the quadrupole. Further, the diffraction plane, or aperture plane, for the total system lies between both combined lenses and fixes a point on the mid-axis, relative to which the combined lenses are arranged, so that the above are anti-symmetric to each other and simultaneously fill the condition that the separation of the first and the second combined lenses from the diffraction plane and the assembly and/or the fields of functionally identical elements in the combined lenses is in a ratio which corresponds to the image scale, preferably, reduction ratio. The shifts of the optical axes of the quadrupole lenses of both combined lenses occur in diametrically opposed directions, such that the size of the shifts are in a ratio to each other which corresponds to the image scale, preferably, the reduction ratio.

    Abstract: An electron beam apparatus has an optical axis, an electron beam source for generating an electron beam directed along the optical axis, and a magnetic field lens having an axis coincident with the optical axis for focusing the electron beam onto a sample which is subjected to a negative voltage so that secondary electrons are emitted from the sample. The magnetic field lens has a conductive cylinder surrounding a part of the optical axis to permit the passage therethrough of an electron beam from the electron beam source. A first detector detects secondary electrons emitted by the sample in a direction away from the optical axis and is disposed at a position generally confronting the conductive cylinder. A second detector is disposed over the conductive cylinder. A Wien filter deflector deflects secondary electrons emitted by the sample toward and for detection by the second detector. The Wien filter deflector is disposed on the optical axis and between the conductive cylinder and the second detector.

    Abstract: An electrostatic-magnetic lens is provided having either a symmetrical or asymmetrical magnetic lens which is overlaid with an electrostatic immersion lens. One electrode of the immersion lens is formed as a hollow cylinder, which is within an upper pole piece of the magnetic lens concentrically relative to the axis of symmetry thereof and extending into the region of the pole piece gap. The lower pole piece of the magnetic lens is preferably at a ground potential and clad with the beam guiding tube for protection against contamination and forming the lower electrode of the electrostatic immersion lens.
