摘要:
An accordion-structured welded bellows for a semiconductor-manufacturing device is characterized in that a plurality of annular bellows plates having curved surfaces in a radial direction are connected in an alternating fashion on the outside-diameter side and the inside-diameter side, wherein the annular bellows plates have a processing-side bellows plate and a non-processing-side bellows plate, a gas layer is interposed between the two bellows plates, the processing-side bellows plate is configured as a thick plate, and the non-processing-side bellows plate is configured as a thin plate. The welded bellows is less likely to be damaged by foreign matter and to be able to use the non-processing-side bellows plate to compensate for any damage to the processing-side bellows plate.

摘要:
A semiconductor fabrication device welded bellows of an accordion structure is characterized in that a plurality of annular bellows plates having faces curving in a radial direction are connected alternatingly at the outside diameter side and inside diameter side, wherein the annular bellows plates are provided with a treatment-side bellows plate and a non-treatment-side bellows plate, a gas layer disposed between the two bellows plates, the treatment-side bellows plate being of lesser thickness, and the non-treatment-side bellows plate being of greater thickness. The bellows are highly resistant to damage caused by foreign matter; or, in the unlikely case that the treatment-side bellows plate becomes damaged, the damage can be compensated for by the non-treatment side bellows plate.

The present invention attracts a wafer 6, placed on a susceptor 5, toward the susceptor 5 by the electrostatic attractive power of an electrostatic chuck electrode 7, varies the output voltage of a variable direct current power source 23 for the electrostatic chuck electrode 7 while measuring the temperature of the wafer 6 by a temperature detection sensor 21; and detects the potential of the wafer 6 based on the output voltage of the variable direct current power source 23 at a time when the temperature of the wafer 6 peaks.
摘要:
The testing performs a vibration excitation testing of a part of the structure, performs a numerical calculus of vibration response of the other parts of the structure, and calculates the vibration response of a whole of the structure by combining these two methods. Testing includes calculating a position of a point of exciting force on the basis of vibration exciting, and calculating a reaction force on the basis of a load detected and the position of the point of exciting force. Then, a displacement of a numerical model is computed by using the reaction force calculated and a known external force, and calculating a vibration exciting machine displacement command value on the basis of the displacement. A drive drives the vibration exciting on the basis of an output thereof. Vibration excitation is performed in the translational direction as well as the rotational direction.

A bump inspecting apparatus lights a spherical solder bump mounted on the surface of a circuit board and has a reinforcing resin applied to the lower half thereof from all circumferential directions with rays of light which intersect at a predetermined angle. An image of the lighted solder bump is captured while the amount of light irradiated upon the central portion of a solder bump is reduced. An object is extracted from image data obtained by the image capture and the area and/or the aspect ratio of the object are confirmed. The quality of the state of the reinforcing resin applied to the solder bump can be inspected.
摘要:
In a conveying apparatus for conveying works between a first lower die and a second lower die in a press machine, a distal end portion of a multi-joint robot is connected to a linear shaft body, and the linear shaft body carries a linearly reciprocating body movable in the directions of the length of the linear shaft body. The linearly reciprocating body is connected to a first detachable holding device that holds a first work. The linear shaft body is connected to a second detachable holding device that holds a second work. The first work is transferred by motion of the linear shaft body and the motion of the linearly reciprocating body carrying the first holding device, and the second work is transferred by motion of the linear shaft body alone. The holding of the first work and the holding of second work are started approximately at the same timing, but the releasing of the first work and the releasing of the second work are performed at different timings in accordance with the positions at which their conveyances are completed.

Provided are a plasma treatment method and a plasma treatment device capable of forming a silicon nitride film having high compressive stress. In the plasma treatment method for depositing the silicon nitride film on a process target substrate by use of plasma of raw material gas containing silicon and hydrogen and of nitrogen gas, ion energy for disconnecting nitrogen-hydrogen bonding representing a state of bonding between the hydrogen in the raw material gas and the nitrogen gas is applied to the process target substrate so as to reduce an amount of nitrogen-hydrogen bonding contained in the silicon nitride film.
