    摘要: That region of a resist film in which a contact is to be formed and that region thereof in which an interconnection is to be formed are respectively irradiated with an electron beam in a dose substantially equal to an optimum dose of the resist film and in a dose less than the optimum dose. Thereafter, the resist film is developed.By performing dry etching, an opening extending to a substrate is provided in the region in which the contact is to be formed, and the surface of an insulating film overlying the substrate is exposed in the region in which the interconnection is to be formed.After depositing a conductive metal film on the whole surface the remaining resist film is removed together with the metal film deposited thereon, whereby the contact and the interconnection are formed.

    摘要: An electron beam drawing apparatus having a grounded conductor for a screening operation in the neighborhood of a detection surface of a detector to detect a reflected electrons obtained by irradiating an electron onto a specimen and a secondary electron generated through the electron irradiation. The conductor has openings to pass therethrough the reflected electron and the secondary electron. As a result, the electric charge accumulated on an organic substance fixed onto the front surface of the detector through the electron irradiation is prevented from exerting an influence on the drawing electron beam.

    摘要: Desired portions of the positive-type photoresist film are irradiated with an electron beam, and regions including at least the regions irradiated with the electron beam are further irradiated with ultraviolet light, followed by developing.The photosensitive radicals are destroyed in the regions which are irradiated with the electron beam. Therefore, the solubility of the photoresist film is not increased even when it is irradiated with ultraviolet light, and resist patterns are formed by developing.

    摘要: An electron beam lithography apparatus is disclosed which has an aperture plate provided with an aperture including an array of repeated unit patterns and an ordinary aperture of a rectangular shape. A region free of the influence of a proximity effect is delineated using the former aperture, and a region affected by the proximity effect is delineated using the latter aperture. The number of repeated unit patterns included in the former aperture is determined considering the number of repeated unit patterns included in a pattern array to be delineated on a substrate. Thereby, the number of electron beam shots is reduced. A plurality of apertures having slightly different aperture widths may be provided for always keeping a pattern line width constant.

    摘要: In an electron beam exposure method for production very high-integration semiconductor devices and its related apparatus in a conventional method, the exposure is divided into fine divisions and carried out by performing a number of shots. However, by utilizing an aperture stop produced by working a single crystalline silicon thin film finely, exposure of a predetermined range is done by one shot. According to the invention, the exposure can be accomplished by the number of shots which is smaller by about two orders than that of the conventional technique and the throughput can be improved remarkably. Since the shot number does not substantially differ depending on whether patterns are complicated or not, individual steps can be processed within substantially identical time.
