Title: Charged-particle beam-forming and imaging sytems
IPC: H01J37/12
Filed: 1971-09-09
Abstract: 1328320 Removing material by fusion STANFORD RESEARCH INSTITUTE 9 Sept 1971 [21 Sept 1970] 42036/71 Heading B3V [Also in Division H1] In the use of a beam of charged particles for forming a pattern on a workpiece in the manufacture of a diffraction grating, an interdigital pattern for a microwave device, an integrated circuit or the like, the beam is directed at the work through one or more apertures and through a mask including a slit, a strong electric field being maintained between the mask and the work so that the slit focuses the beam transversely of the slit. If the particles are electrons they are used to expose a resist on the surface of the work; ions may be used in the same way or may be implanted in semi-conductive or insulating material, or may react chemically with the work, or may sputter the work. In one example, Fig. 1 (not shown), electrons are focused by a lens on a single aperture which forms a virtual source illuminating the work through the mask. If the latter contains an L- shaped slit, the exposed pattern is an L with the lines reduced in width by the focusing effect to, for example, ¢ micron. If the source comprises a column of apertures suitably spaced, the exposed pattern is a number of parallel horizontal lines joined at one edge by a vertical line (Fig. 4B, not shown). An interdigitated pattern may be produced by two exposures of a shallow U- shaped slit (Fig. 5A, not shown) illuminated by a column of apertures, one limb of the U being masked for each exposure and the beams on the mask being displaced or deflected between exposures to interleave the two patterns (Fig. 5B, not shown). Alternatively the source may comprise two columns of apertures (Fig. 6, not shown) and an auxiliary mask (Figs. 7 and 8, not shown) is provided to prevent each column from illuminating one limb of the U, so that the interdigitated pattern may be produced by a single exposure. The slit may have any desired shape such as a deep U, an arc, or a cross (Figs. 9A-9C, not shown), and the width of the slit need not be constant.

Abstract: 1,041,138. Moulding soil blocks. MACHINENFABRIEK EN HANDELMAATSCHAPPIJ "WINEL" N.V. Oct. 19, 1964, No. 42476/64. Heading B5A. In a machine for moulding soil blocks, earth is deposited, from a hopper 6, on to an intermittently moving conveyer 1, covered by a sprinkling of sand from box 56, and then moulded at station 7. The moulded blocks are transferred, over bridge 43, on to a second intermittently moving conveyer 44 and thence on to the ground. The whole machine is supported by wheels 4 which are rotated synchronously with conveyers so that the whole machine moves stepwise backwards over the ground, and thus deposits a line of blocks thereon. The conveyer 1 is driven from a rotating arm 38 by means of a connecting arm 39, an angled lever 40 and a ratchet and pawl mechanism 41, 42, mounted upon roll 3 over which the conveyer passes. Rods 47 and 51, mounted upon lever 40, drive ratchet and pawl mechanisms 49, 50 and 53, 54 respectively which mechanisms respectively drive the conveyer 44 and wheels 4. At the moulding station, the earth is moulded by vertically reciprocable cutting moulds 10 having pegs (not numbered); for forming dents in the blocks. Slidable about the moulds are plates 36 and 37 carried by a plate 29, which also carries a series of plates 27 slidable within each mould. The plates and moulds are first lowered to the position shown in Fig. 6 (not shown), in which blocks are formed by the moulds, the earth to be used next cycle is pre-compressed by plate 37, and the blocks formed by the previous cycle are engaged by plate 36. The pegs and moulds are then raised to the position shown in Fig. 7 (not shown), during the first part of which movement, the plates 27, 36 and 37 remain lowered to prevent adhesion of the earth to the moulds. The plates are then re-raised, the conveyers indexed forward, and the members relowered in unison to initiate another cycle.
