Title: Resist pattern forming method
Inventor: AOYAMA SATORU
IPC: G03F1/22
Filed: 1989-12-08
Abstract: PURPOSE:To form a finer resist pattern by forming a second resist sensitive to charged corpuscular beams or electromagnetic waves having shorter wavelength than UV on the whole of one principal face of a first resist and by selectively irradiating the surface of the second resist with charged corpuscular beams or electromagnetic waves having shorter wavelength than UV. CONSTITUTION:A positive type resist 2 for a first layer is formed on one principal face of a substrate 1 and baked. A positive type resist 3 for a second layer having low transmittance at the wavelength of light used to expose the resist 2 and sensitive to electromagnetic waves having shorter wavelength than UV is formed on one principal face of the resist 2. The surface of the resist 3 is then selectively irradiated with charged corpuscular beams 4A. Since the beams 4A travel straight and electromagnetic waves having shorter wavelength than UV undergoes a lower degree of diffraction than UV, the second resist can be accurately patterned by a irradiation with the beams 4A or the electromagnetic waves and a finer prescribed resist pattern can be formed.

Abstract: PURPOSE:To reduce the variation of individual semiconductor devices in a wafer surface and improve a yield by a method wherein a parallel panel heater is employed, a second electrode is made to face down and heat is transmitted uniformly over the whole rear of the wafer. CONSTITUTION:A quartz plate 3 is placed on a parallel panel heater 4 and a thermal cushion material 2 is laid on the quartz plate 3 in order not transmit heat to the quartz plate 3 and a semiconductor wafer 1 quickly and the semiconductor wafer 1 is put on the thermal cushion material 2 so as to have its rear face down. The heat applied to the wafer 1 is controlled by putting or removing the whole quartz plate 3 onto or from the heater 4. The wafer 1 is cooled by making N2 gas flow along the surface of the wafer 1 and, on the other hand, by the heat transmission from the rear of the wafer 1 to the quartz plate 3 through the thermal cushion material 2. By this electrode forming method, a thermal stress applied to a Schottky barrier electrode 7 on the wafer surface can be very little.

Abstract: PURPOSE: To make it easy to remove a drive shaft and to support it without being influenced by the vertical motion of an engine by piercing the midway portion of the drive shaft through the cylinder part of a propulsion device housing and support the drive shaft rotatably through a flat bearing with a damper. CONSTITUTION: When ship body tides over a high sea, an engine 6 makes a vertical motion relatively to the ship's bottom 2a by inertia force acting thereon.

For this reason, the condition of the drive shaft 12 supporting the engine 6 is kept almost the same as before displacement. When the drive shaft 12 is removed for maintenance or other reason, a connecting part 31 on its front end is removed from the drive shaft by pulling it backward with respect to a pump housing 11 and drawn out from the flat bearing with a damper 24, a bearing member 23, a seal member 25 and a cover 26.
