The present invention enables a member to be accurately fixed to a floor. With tapped holes 5 in a member mounting section 2 accurately aligned with marks formed in a grating 20 so as to correspond to through-holes 9, a bolt 14 is screwed in an internal thread cylinder 23 (fixed in a vent hole 21 in the grating 20) through a through-hole 13 in a presser plate 12 that can have its position changed relative to the member mounting plate 2, and the presser plate 12 is used to fix the member mounting plate 2 to the grating 20.

An apparatus for optically reproducing digital speech data recorded on a motion picture film is disclosed. The digital speech data recorded on an emulsifier surface of the motion picture film is illuminated with an illuminating light from the side of a base surface of the motion picture film, and the light transmitted through the emulsifier surface is collected as an incident light by a reproducing lens. With the present apparatus, it is possible to reduce the variations in the volume of the light of the reproduced digital signals otherwise caused by the scratch of dust present on the film base surface.

In one embodiment, a method of cleaning a semiconductor manufacturing apparatus includes supplying a cleaning gas for removing a deposition film deposited on an inside wall of a treatment chamber through a supply pipe of the treatment chamber so that a supply amount of the cleaning gas from the supply pipe per unit time is greater than an exhaust amount of the cleaning gas from an exhaust pipe of the treatment chamber per unit time. The method further includes supplying an inert gas to fill the supply pipe with the inert gas.

According to one embodiment, a cleaning gas is sealed in a chamber of a semiconductor manufacturing apparatus, and the cleaning gas and deposits adhered in the chamber are reacted with each other to generate a reactive gas. After a predetermined time, the gas is exhausted from the chamber. Then, the chamber is evacuated while the cleaning gas is introduced into the chamber, and the reactive gas concentration contained in an exhausted gas is measured. The reactive gas concentration is compared with a determination value obtained when the deposits are removed from the chamber to determine whether the cleaning is terminated.

In a manufacturing process of a semiconductor device by forming a structure film on a substrate in a reaction chamber of a manufacturing apparatus, cleaning inside the reaction chamber is performed. That is, a precoat film made of a silicon nitride film containing boron is deposited on an inner wall of the reaction chamber, a silicon nitride film not containing boron is formed as the structure film on the substrate in the reaction chamber, and the inner wall of the reaction chamber is dry etched to be cleaned. At this time, the dry etching is terminated after boron is detected in a gas exhausted from the reaction chamber.

A method of manufacturing a semiconductor storage device includes providing an opening portion in a plurality of positions in an insulating film formed on a silicon substrate, and thereafter forming an amorphous silicon film on the insulating film, in which the opening portions are formed, and in the opening portions. Then, trenches are formed to divide the amorphous silicon film, in the vicinity of a midpoint between adjacent opening portions, into a portion on one opening portion side and a portion on the other opening portion side. Next, the amorphous silicon film, in which the trenches are formed, is annealed and subjected to solid-phase crystallization to form a single crystal with the opening portions used as seeds, and thereby a silicon single-crystal layer is formed. Then, a memory cell array is formed on the silicon single-crystal layer.
