In a method for forming a pattern, by selectively irradiating a charged particle beam onto a substrate in an atmosphere containing a raw material gas, a resist pattern comprising a material which is produced on the substrate from the raw material gas is formed, wherein a pressure of the raw material gas is set to 10.sup.-7 to 10.sup.-5 Torr, an accelerating voltage of the charged particle beam is set to 0.5 to 6 kV, and a beam current of the charged particle beam is set to 10.sup.-13 to 10.sup.-7 A. Thus, a resist pattern of an ultrafine width can be stably formed in a relatively short time.Further, in a method for forming a pattern, by irradiating a charged particle beam onto a substrate in an atmosphere containing a gaseous negative type resist, a cross-linking reaction of the negative type resist molecules adsorbed on the surface of the substrate is caused, and a pattern comprising the negative type resist molecules which caused the cross-linking reaction is formed, so that a pattern which has an ultrafine width and can be easily removed by the wet process can be formed.

摘要:
In recent years the induction motor speed has come to be controlled by changing the frequency and voltage of the commercial power supply by means of an invertor. The frequency of the commercial power supply, however, differs from country to country and even in the same country differs from region to region. If the motor controller designed for a supply frequency of f.sub.L is operated connected to the supply having a frequency f.sub.H higher than f.sub.L, an overvoltage will result. Conversely, if the motor controller designed for a supply frequency of f.sub.H is connected to the supply with a frequency f.sub.L lower than f.sub.H, then a sufficient torque cannot be obtained. To eliminate the above drawback, the present invention detects the input frequency of the motor controller and selects or calculates control constants in accordance with the detected value so as to enable stable operation even when the input frequency changes.

Provided are a sleeping state detection system and method that can detect the sleeping state of a subject such as an inpatient or a tenant without causing the subject stress, and that can ascertain the health state of the subject from the detection results. The sleeping state detection system includes a room or closed space (201) in which the subject sleeps, and a dust counter (206) that measures the dust particles inside the room or closed space (201). In a state where the inside of the room or closed space (201) is kept cleaner than the outside of the room or closed space (201) by using a fan filter unit (208) disposed in the room or closed space (201), while the subject sleeps, the change over time in the number of dust particles inside the room or closed space (201) is measured using the dust counter (206), and thereby the sleeping state of the subject is detected. The inside of the room or closed space (201) is preferably kept at a cleanliness of US 209D Class100 or better.

A device manufacturing method and a device manufacturing apparatus in a single wafer processing system with wafers in 0.5 inch size. A large number of sealed-type unit process apparatuses are arranged to form a manufacturing line. The unit process apparatus is portable and processes a single process in the manufacturing process. When the number of a unit of manufacturing is more than the number of the unit process apparatuses, the unit process apparatuses are arranged as a flow shop system, corresponding to the order of processes for the device. When the number of the units is nearly equal to the number of processes, the apparatuses are arranged as a class shop system for classified arrangement at every major division of orders of processes. When the number of the units is far less than the number of processes, the apparatuses are arranged as a multicell shop system.
