    摘要: A pressure type flow rate control apparatus (1) controls flow rate of a fluid in an environment where a ratio of P2/P1 between an absolute pressure P1 at an upstream side of an orifice and an absolute pressure P2 at a downstream side of the orifice is maintained at a value less than about 0.7. The apparatus comprises: a plate for forming the orifice (5); a control valve (2) positioned upstream of the orifice; an orifice corresponding valve (9) positioned downstream of the orifice (5); a primary pressure detector (3) positioned between the control valve (2) and the orifice (5); a secondary pressure detector (11) positioned downstream of the orifice (5); a calculation control device (6) for calculating flow rate Qc on the basis of the measured pressure P1 of the primary pressure detector (3) by a formula Qc = KP1 (K being a constant) and for outputting as a control signal Qy a difference between a flow rate command signal Qs and the calculated flow rate signal Qc to a drive unit (14) of the control valve 2; and a pressure comparing, calculating apparatus (10) for calculating the ratio of P2/P1 between the detected pressure P1 of the primary pressure detector (3) and the detected pressure P2 of the secondary pressure detector (11). The pressure P1 upstream of the orifice is adjusted by opening and closing the control valve by the control signal Qy, thereby controlling the flow rate downstream of the orifice.

    摘要: An excimer laser generating system includes a laser chamber (1) whose inner surface (101) is covered with a fluorine-passivated surface. Preferably, the surfaces (102,103) of a blower (23) and heat exchanger (24) disposed in the laser chamber(1) are also covered with a fluorine-passivated surface. The fluorine-passivated surface (101,102,103) may be formed of a wide variety of materials including an aluminum oxide film, a fluoride film containing aluminum fluoride and magnesium fluoride, iron fluoride, and nickel fluoride. Preferably, the excimer laser generation system includes a gas supply system having an inert gas purging system so that gas sources can be replaced without exposing the inside of gas supply pipes to atmosphere. With the above arrangement, the excimer laser generating system can generate a laser beam pulse whose energy and shape are maintained constant for a long period of operation time without encountering serious degradation. The invention also provides a high-reliability step-and-repeat exposure apparatus using the above excimer laser generating system, capable of exposing a very fine pattern.

    摘要: Neutralizing equipment which can realize simply and effectively the removal of the charges on a charged body such as a wafer which is easily charged. For example, after such an easily chargeable body as a wafer (3) is transported into a case (1), if neutralizing-charge producing means which are typically light sources (8a, 8b) for projecting ultraviolet rays for exciting into the case (1) is operated, the case (1) is filled with ions which are produced by ionizing the atmosphere gas, etc. of a nonreactive gas, etc. introduced beforehand in the case (1). Hereupon, the neutralizing-charge producing means can produce positive and negative ions and electrons. When the body is charged positively, the electrons or negative ions are moved toward the charge body to neutralize the positive charges on the charged body. On the other hand, when the body is charged negatively, the positive ions produced in the case (1) are moved toward the charged body to neutralize the negative charges thereon.
