The present invention aims to stabilize sound-electricity conversion characteristics of a diaphragm-type sound-electricity conversion device as well as to decrease the noise level of an ultrasonic diagnostic apparatus using the sound-electricity conversion device. The sound-electricity conversion device is configured by a capacitor cell including a lower electrode formed on a silicon substrate and an upper electrode over the lower electrode, the lower and upper electrodes sandwiching a cavity. An electrode short-circuit prevention film is formed on the upper electrode on the cavity side. The electrode short-circuit prevention film is formed of a material with an electrical time constant shorter than 1 second and longer than 10 microseconds, such as silicon nitride containing a stoichiometrically excessive amount of silicon. As a result, the electrode short-circuit prevention film has small electric conductivity, and thus it is made possible to prevent the film from being charged with electric charge and to avoid the drift of the electric charge. Consequently, the sound-electricity conversion characteristics of the sound-electricity conversion device stabilize, and further the sound noise level of the ultrasonic diagnostic apparatus decreases.

There are provided a culture treatment apparatus and an automatic culture apparatus capable of taking quick and appropriate action even if there is a change in the state of a space where cells stored in a container, such as a culture vessel, for the automatic culture apparatus are subjected to predetermined treatment. The culture treatment apparatus includes a treatment section for applying predetermined treatment to cells stored in an openable container for the automatic culture apparatus in a partitioned space; a detection section for detecting a predetermined state of the space, the detection section being in the space or in the vicinity of the space; and a control section for controlling the treatment section to close the container if the detection section detects the predetermined state with the container opened.

Equipment extracts components of spatial frequency that need to be evaluated in manufacturing a device or in analyzing a material or process out of edge roughness on fine line patterns and displays them as indexes. The equipment acquires data of edge roughness over a sufficiently long area, integrates a components corresponding to a spatial frequency region being set on a power spectrum by the operator, and displays them on a length measuring SEM. Alternatively, the equipment divides the edge roughness data of the sufficiently long area, computes long-period roughness and short-period roughness that correspond to an arbitrary inspection area by performing statistical processing and fitting based on theoretical calculation, and displays them on the length measuring SEM.

Upon formation of semiconductor micro patterns, an interlayer alignment error occurs due to asymmetry of each alignment mark. Prior to alignment of a mask with a wafer, the asymmetry of each alignment mark is measured according to the principle of a scatterometry, and the alignment is performed in consideration of the result of measurement to execute exposure. Thus, high-accuracy alignment can be carried out without sacrificing throughput, and the performance of a semiconductor device is improved. Further, manufacturing yields can be enhanced and a reduction in cost can be realized.

A method for manufacturing an electronic device is provided. In one example of the method, the method prevents deformation of a resist mask caused by the irradiation of exposure light. The resist mask has a resist as an opaque element, and can afford mask patterns undergoing little change even with an increase in the number of wafers subjected to exposure processing. The resist mask maintains a high dimensional accuracy. A photomask pattern is formed using as an opaque element a resist comprising a base resin and Si incorporated therein or a resist with a metal such as Si incorporated thereby by a silylation process, to improve the resistance to active oxygen. The deformation of a resist opaque pattern in a photomask is prevented. The dimensional accuracy of patterns transferred onto a Si wafer is improved in repeated use of the photomask.

A printer prints a calibration pattern on a leading end portion of a roll of recording paper when the recording paper is loaded in the printer. A cutter cuts the leading end portion off the recording sheet so as to make an end edge rectangular to side edges of the recording sheet. A photometric device measures densities of the printed calibration pattern, and a system controller derives correction values for correcting density or color from the measured densities. After the calibration process, an image is printed in an image recording area on the recording paper following the leading end portion. For a printer that prints an image on a cut sheet recording paper, a calibration pattern is printed on a margin outside an image recording area. After densities of the calibration pattern are measured, the margin with the calibration pattern is cut off the recording paper.

There is disclosed a thermosensitive line printer, wherein a heating element array of a thermal head is pressed on a thermosensitive recording paper at a distance L2 from a nipping position by a pair of conveyer rollers, and is driven to record an image frame line by line from a print starting end, as the recording paper is conveyed by the conveyer rollers in a direction from the thermal head to the conveyer rollers. Based on image data of an upper zone of an image frame that is to be recorded around the distance L2 from the print starting end if the image frame is recorded from its top side, an image analyzer calculates a first estimation value that represents conspicuousness of potential density deviation in the upper zone that could be caused by a thermal deformation of the thermosensitive recording paper at the print starting end if the image frame is recorded from the top side. The image analyzer calculates a second estimation value based on image data of a lower zone that is to be located at the distance L2 from the print starting end if the image frame is recorded from its bottom side. If the first estimation value is smaller than the second estimation value, the image frame is recorded from the top side, and vise versa.

Method and apparatus for processing substrates through a number of wet treatments. A substrate is set on a substrate rotating means for rotation in a horizontal face-up position, within a housing which is open on its top side. By a treating liquid feed means having a treating liquid feed nozzle member, at least one kind of treating liquid is supplied onto upper surfaces of the substrate being rotated by the substrate rotating means. The treating liquid feed nozzle member is supported on a movable arm for displacement to and from an operative position vertically confronting the substrate and a receded standby position away from the substrate on the substrate rotating means. Located face to face with lower surfaces of the substrate is a nozzle means which supplies a fluid to the lower side of the substrate.
