摘要:
Effects of synchronization control errors on subsequent processes are reduced when such synchronization control errors occur in a scanning type (e.g., step-and-scan) exposure apparatus. A reticle stage controller that controls the driving of a reticle stage, a focus controller that controls a focusing position on a wafer, a blind controller that controls a shape of an aperture formed by a movable blind, and an exposure controller that controls the intensity of light incident on the wafer are controlled with as much precision as is possible, but typically have synchronization control errors. Synchronization control errors for each controller are determined, e.g., by each controller, and are supplied to a main control system that can be, e.g., a higher rank controller. The main control system displays, e.g., through a warning apparatus, shot areas in which the synchronization control errors exceed an allowable range. Such shot areas are referred to as poor shots. The poor shots are eliminated from being exposure targets in subsequent exposure processes (e.g., for layers applied above the layer causing the poor shot) and also are eliminated from being used as sample shots in subsequent alignment processes.

What is provided is a liquid supply container capable of minimizing, after the supply of liquid in a liquid reservoir to a liquid acceptor has been completed, the amount of the liquid remaining in the liquid reservoir. A liquid supply container 1 includes: a liquid reservoir 10 that changes its shape in accordance with the amount of liquid contained therein; and a liquid supply section 30 provided in the liquid reservoir 10 to supply the liquid to a liquid acceptor 50. The liquid supply section 30 includes: a liquid supply path 16 that supplies the liquid to the liquid acceptor 50; and an exposed surface 20 that defines a liquid reservoir 10-side end in the liquid supply path 16 and is exposed to the inner space of the liquid reservoir 10. The exposed surface 20 is provided with a recess capable of forming a flow path in which the liquid flows from the outer circumference of the exposed surface 20 to the liquid supply path 16. Also, a liquid supply container 2 has a recess or protrusion on the inner surface of the liquid reservoir 10, the recess or protrusion being capable of forming a flow path in which the liquid flows to the liquid supply path 16.

A liquid property sensor for detecting property of liquid includes a semiconductor board, a first electrode and a second electrode, and a protection film. The first and second electrodes are disposed on the semiconductor board to be spaced from each other at a predetermined distance. The protection film has resistance relative to the liquid, and is exposed to the liquid. The first and second electrodes detect a capacitance therebetween as the property of the liquid in accordance with a relative permittivity of the liquid. A capacitance-voltage conversion circuit of the semiconductor board converts the capacitance into a voltage value.

A semiconductor physical quantity sensor includes: a substrate; a semiconductor layer supported on the substrate; a trench disposed in the semiconductor layer; and a movable portion disposed in the semiconductor layer and separated from the substrate by the trench. The movable portion includes a plurality of through-holes, each of which penetrates the semiconductor layer in a thickness direction. The movable portion is capable of displacing on the basis of a physical quantity applied to the movable portion so that the physical quantity is detected by a displacement of the movable portion. The movable portion has a junction disposed among the through-holes. The junction has a trifurcate shape.

An exposure apparatus is provided with temperature sensors (25 and 26) to measure temperatures of air around laser beams from a reticle-side laser interferometer (22a) and a wafer-side laser interferometer (23a), together with an environmental sensor (31) for measuring an atmospheric pressure, humidity, and so forth. A main control system (13) as a host CPU instructs a reticle stage control system (27) and a wafer stage control system (28) to move a reticle and a wafer, respectively (step 201). During the reticle and wafer moving period, measured values by the temperature sensors (25 and 26) and the environmental sensor (31) are read, and a variation of the laser wavelength due to a change in the environmental data is corrected (step 202), and during subsequent scanning exposure, position control of the reticle and wafer stages is effected by using the corrected laser wavelength. Thus, the laser wavelength of the laser interferometers is corrected without an increase in the cost or a reduction of the throughput.

The objective of the present invention is to provide a reciprocation switching device for a pump which will solve problems of conventional devices such as that, because coil springs are used for activating by their snap action valve operators or switching operators serving to control the pressure of pump working fluid in relation to reciprocating action of the pump, such devices require the numerous number of parts including spring fitting shafts, the structure to attach such fitting shafts, parts for spring holders, etc.; and that the assembling of those parts is troublesome. A device according to the present invention uses one or two wire springs made into a C-like shape as the springs for the aforementioned purpose and calls for fitting said springs directly between the spring fitting sections(s) and the valve operator or the switching operator.
摘要:
A spool type switching valve to be used for the switching operation of a diaphragm pump or a similar device, which simultaneously insures both preventing abrasion of the detent mechanism and obtaining thorough operation of switching the spool. A spool is movably fitted inside a sleeve and is prevented from standing still at a neutral point by a detent mechanism provided at one of its ends. The detent mechanism comprises a spool operator fitted around a shaft section at one end of the spool as one body, a spring holder at the end of the sleeve retains a pair of C-shaped wire springs of a circular cross-section fitted between the spool operator and the spring holder. As the spool passes the neutral point, spring forces snap the spool to the extremity of its range, thereby preventing stopping of the spool in the neutral position. An axial clearance permits the spool operator to begin moving before the spool moves.

A valve body for pumps has a compressed air-filled chamber in the center thereof and a compressed air supply port through which compressed air is supplied into the compressed air-filled chamber. The outer surface of the valve body is provided with an annular groove-shaped air supply chamber that communicates between the compressed air-filled chamber and a pump-side air chamber. Compressed air supplied into the compressed air-filled chamber through the compressed air supply port is supplied into the pump-side air chamber through the air supply chamber.
