    摘要: According to the invention an electron beam pattern transfer device with an improved alignment means is provided.A first and a second mark M.sub.1, M.sub.2 for alignment purposes are formed on the surface of the wafer and the wafer holder, respectively. The first mark M.sub.1 is formed on the wafer by conventional lithographic technique and the second mark M.sub.2 consists of a hole or a heavy metal, such as Ta or Ta.sub.2 O.sub.5. A third alignment mark M.sub.3 is provided on the photocathode mask having a position corresponding to M.sub.2 on the wafer holder and spaced a known distance L.sub.2 from an imaginary reference position M.sub.4 on the mask. The first step of the alignment process requires the detection of a relative distance L.sub.1 between the first and second marks M.sub.1, M.sub.2 by conventional detecting means, such as an optical measuring means. In the next step, the relative position of the photocathode mask and the wafer holder is adjusted so that the distance between the marks M.sub.2 and M.sub.3 is made substantially equal to the difference between the distance L.sub.1 and the known distance L.sub. 2.

    摘要: An electron beam type pattern transfer apparatus has a photoelectric mask and a sample in a vacuum container made of non-magnetic material. The photoelectric mask is adapted to receive an ultraviolet ray from a light source and emit photoelectrons corresponding to a predetermined transfer pattern and the sample is disposed in parallel with the photoelectric mask with a predetermined distance left therebetween and illuminated with the photoelectrons to form a resist image thereon which corresponds to the transfer pattern. A power source for applying a voltage for accelerating the photoelectrons emitted is connected between the photoelectric mask and the sample. A pair of focusing magnets are disposed around the axis of the vacuum container such that they are located one at one outer side and one in an opposite outer side of the vacuum container to permit a vertical magnetic field to be created between the photoelectric mask and the sample. The focusing magnets have superconductive coils and are driven in a persistent mode.

    摘要: An electron beam pattern transfer system is disclosed which includes a photoelectric transducing mask disposed within a vacuum container and adapted to transfer a photoelectron beam pattern corresponding to a pattern of the mask onto a sample according to an amount of an incident light, a DC voltage generator connected to vary a voltage applied between the mask and the sample, and a focusing coil of a superconductive magnet for creating a magnetic field of a predetermined intensity between the mask and the sample. When a mask-to-sample distance and/or magnetic field intensity varies undesirably, the variation is electrically detected by detectors. In order to compensate for the defocusing of the photoelectron beam pattern on the sample due to the above-mentioned variation, a microprocessor automatically calculates an amount of correction with respect to the intensity of the electric field between the mask and the sample, on a real-time basis and supplies its control signal to the DC voltage generator.
