Filed: 1991-05-10
Abstract: PURPOSE:To dispense with removal and reapplication of lower layer resist and to shorten time required for reexposure by underlaying the upper layer or the medium layer resist with a film of water-soluble organic material. CONSTITUTION:A lower layer resist 4 is applied over a silicon substrate 1 and then hard-baked. A water-soluble polymer organic film 6 is applied and then baked. Further, an upper layer resist 2 is applied and baked. The substrate is partially irradiated with electron beams 3 and then subjected to spray development and spray rinsing to obtain an upper resist pattern 2a. With this pattern as a mask, the polymer organic film 6 and the lower layer resist 4 are simultaneously worked by O2RIE to form a required pattern 4a. In the case of another exposure on the same substrate because the upper layer resist pattern 2a turns out to have design mistakes after being formed, the substrate surface is washed with pure water and dried for removal of the resist pattern 2a and the polymer organic film 6, so that only the lower layer resist 4 remains on the substrate 1.

Abstract: PURPOSE:To aim at a reduction in the handling time of a ship, by storing the coal carried in by a conveying device in a coal yard, while controlling the date and hour of departure from the base of a freight train to a coal shipping base which delivers coal to its consumer destination by ship. CONSTITUTION:When a load material is coal by way of example, he coal is directly conveyed to a ship A from a coal acceptance installation 11, while a freight train is temporarily made to stay in a sidetrack 19. In addition, an input device 21 inputs the scheduled date of arrival in the ship A, a demanded description and the amount demanded while a control device 20 sets the date and hour of coal shipment of the train so as to cause at least the date of coal loading on the ship A to accord with the scheduled date of arrival of the ship A. With this constitution, direct delivery can be carried out at high frequency without setting up a vast sidetrack. Therefore, demurrage time is shortened so that such an effect that a coal handling quantity at a coal shipping port is much increased and, what is more, one more good effect that a penalty due to demurrage is no longer subjected is thus securable.
