A robot having a robot arm swingable from a position outside a car body conveying line to the line and movable in the directions of length, width and height of the car body is provided with a support frame carrying a jig for holding the window glass. The frame is tiltably mounting on the arm via a tilting shaft. A first detector is mounted on the frame for detecting a deviation the car-width direction of the jig with respect to the window portion. A pair of second detectors are provided on the frame at positions which are symmetrical with respect to the car width direction center line of the jig for detecting deviations in the plane of the window opening. First, deviation detected by the first detector is corrected by moving the jig in the car width direction. Then, deviation in tilt detected by the second detectors is corrected by tilting the jig. Finally, deviation in height detected jointly by the second detectors is corrected by raising or lowering the jig. Thereafter, the window glass is mounted in the window portion.

On a semiconductor substrate are successively deposited a silicon dioxide film and a silicon nitride film. The silicon nitride film, the silicon dioxide film, and the semiconductor substrate are sequentially etched using a photoresist film with an opening corresponding to an isolation region, thereby forming a trench. After depositing a diffusion preventing film, there is deposited an insulating film for isolation having reflowability. Although a void is formed in the insulating film for isolation in the isolation region, the insulating film for isolation is caused to reflow, thereby eliminating the void. After that, the whole substrate is planarized by CMP so as to remove the silicon nitride film and the silicon dioxide film, followed by the formation of gate insulating films, gate electrodes, sidewalls, and source/drain regions in respective element formation regions. Thus, in a highly integrated semiconductor device having a trench isolation, degradation of reliability resulting from the opening of the void in the surface of isolation is prevented.

A semiconductor apparatus with MOS transistors for transmitting electrons from an n type source layer to an n type drain layer through a first channel region in an n-channel MOS transistor and transmitting holes from a p type source layer to a p type drain layer through a second channel region in a p-channel MOS transistor consists of a field oxide layer for separating the n-channel MOS transistor from the p-channel MOS transistor, an n type gate electrode mounted on a first gate oxide film arranged on the first channel region, a p type gate electrode mounted on a second gate oxide film arranged on the second channel region and positioned far away from the n type gate electrode to prevent impurities implanted into one of tile gate electrodes from diffusing into the other gate electrode, and a gate metal wiring connecting the gate electrodes through a gate contact hole to miniaturize the transistors.

Gate electrodes of an N-channel transistor and a P-channel transistor are formed on a semiconductor substrate with a gate insulator therebetween. After conducting a first thermal treatment to the gate electrodes, N-type heavily doped diffusion layers to be a source or a drain of the N-channel transistor are formed using the gate electrode of the N-channel transistor as a mask. After conducting a second thermal treatment to the N-type heavily doped diffusion layers at a lower temperature than that of the first thermal treatment, P-type heavily doped diffusion layers to be a source or a drain of the P-channel transistor are formed using the gate electrode of the P-channel transistor as a mask. Then, a third thermal treatment is conducted to the P-type heavily doped diffusion layers at a lower temperature than that of the second thermal treatment.

An image forming apparatus which is capable of reducing the number of times a second member is separated from a first member upon entry into power-save mode, thereby minimizing failures of a separation unit. A pressure-roller separating mechanism is provided so as to abut and separate a pressure roller and a fixing roller against/from each other. The image forming apparatus is controlled to change to a power-save mode in which power consumption of the image forming apparatus is reduced. The pressure-roller separating mechanism is controlled to separate the pressure roller and the fixing roller from each other in the power-save mode based on a measurement result measured by a timer, and the power-save mode is maintained after the pressure roller and the fixing roller are separated from each other.
摘要:
An isolation which is higher in a stepwise manner than an active area of a silicon substrate is formed. On the active area, an FET including a gate oxide film, a gate electrode, a gate protection film, sidewalls and the like is formed. An insulating film is deposited on the entire top surface of the substrate, and a resist film for exposing an area stretching over the active area, a part of the isolation and the gate protection film is formed on the insulating film. There is no need to provide an alignment margin for avoiding interference with the isolation and the like to a region where a connection hole is formed. Since the isolation is higher in a stepwise manner than the active area, the isolation is prevented from being removed by over-etch in the formation of a connection hole to come in contact with a portion where an impurity concentration is low in the active area. In this manner, the integration of a semiconductor device can be improved and an area occupied by the semiconductor device can be decreased without causing degradation of junction voltage resistance and increase of a junction leakage current in the semiconductor device.
摘要:
A conductive film for gate electrode including a polysilicon film is deposited on a semiconductor substrate, and patterned to form gate electrodes. An oxide film is formed on each side face of at least the polysilicon film, and by nitriding at least the surface portion of the oxide film, a nitride oxide film is formed on each side face of the gate electrodes. An interlayer insulating film is then deposited, and contact holes are formed through the interlayer insulating film. The existence of the nitride oxide film suppresses variation and reduction in size due to oxidation and etching of the gate side faces during resist removal and washing.
