Abstract:
The placement of a wafer can be performed with good positional precision, and the positioning of wafer clamps during maintenance is facilitated. A tapered recess is formed in that portion of the wafer support on which a wafer is placed. When a wafer is placed in the recess, the sloped surface inside this recess comes into contact with the edge of the wafer from beneath the wafer. The wafer is supported in a specific attitude by the sloped surface inside this recess.
Abstract:
An extruding coating method comprises steps of feeding a coating liquid into a coating liquid reservoir section provided with a slit having a slit width; and extruding the coating liquid through the slit so as to conduct coating, wherein the coating liquid is extruded through the slit by pushing the coating liquid in the coating liquid reservoir toward all over the slit width by a piston.
Abstract:
Methods and apparatuses for efficiently forming a homogeneous glass layer having uniform thickness and a homogeneous metal layer having uniform thickness are provided. A workpiece is accommodated in a screened container which is rotatable in a predetermined direction. The workpiece in the container is sprayed with an atomized glass slurry or an atomized metal slurry while the container is rotated in order to form a green glass layer or a green metal layer on the workpiece. Simultaneously, hot air is supplied to the workpiece so as to dry the green glass layer or the green metal layer. Thus, the workpiece, typically a ferrite core, can be provided with a homogeneous layer having a uniform thickness. A method for manufacturing an electronic component using the above-described methods and apparatuses is also provided.
Abstract:
A solvent of a resist solution is dropped from a solvent supply nozzle onto the surface of a semiconductor wafer held by a spin chuck. The semiconductor wafer is rotated by the spin chuck to spread the resist solution over the entire surface of the semiconductor wafer W. Simultaneously, the resist solution is dropped from a resist solution supply nozzle onto the semiconductor wafer and spread following the solvent. During the processing, the processing space is isolated from the outer atmosphere by closing a lid of a processing vessel and a sprayed solvent is supplied into the processing space. The processing space is thus filled with the mist of solvent. In the processing space supplied with the solvent, evaporation of the solvent from the resist solution is suppressed. A film of the resist solution is formed with a uniform film thickness to the edge of the semiconductor wafer W.

Abstract:
An apparatus for coating stent is disclosed. The apparatus can be used to coat multiple stents or a large number of stents simultaneously. The apparatus includes a chamber that can be rotated or tumbled during the application of a coating substance to the stents.
Abstract:
A substrate treating apparatus disclosed herein realizes improved throughput. The substrate treating apparatus according to this invention includes an antireflection film forming block, a resist film forming block and a developing block arranged in juxtaposition. Each block includes chemical treating modules, heat-treating modules and a single main transport mechanism. The main transport mechanism transports substrates within each block. Transfer of the substrates between adjacent blocks is carried out through substrate rests. The main transport mechanism of each block is not affected by movement of the main transport mechanisms of the adjoining blocks. Consequently, the substrates may be transported efficiently to improve the throughput of the substrate treating apparatus.
Abstract:
The magnetic tape manufacturing apparatus draws out a wide web-like magnetic tape material wound in roll form from the delivery side, slits the magnetic tape material into a plurality of narrow magnetic tapes by use of a slitter while transporting the magnetic tape material, and winds the narrow magnetic tapes on cores on the winding side through a tape transporting device. In the tape transporting device, roller members supporting the narrow magnetic tapes are mounted on supporting shafts, respectively, and an eddy current type clutch is internally mounted on at least one of the supporting shafts so that the eddy current type clutch controls rotation of the one of supporting shafts to control tension of the narrow magnetic tape supported on the roller member mounted on the one of supporting shafts. Hence, by making the tension of the individual magnetic tapes uniform, productivity and product quality can be stabilized and improved and yield can also be improved.
Abstract:
An article (e.g. a semiconductor wafer) is held in an article holder by means of a number of gas flows emitted from gas vortex chambers. Some of the gas flows act to cool an adjacent article portion more than the other gas flows. For example, some of the vortex chambers emit more gas per unit of time than the other chambers. More cooling is provided to those portions of the article which are heated more during processing. Greater temperature uniformity can be achieved.
