Abstract:
An apparatus that uses an optimized body design incorporating one or more interchangeable nozzle inserts with a wide array of discharge orifice sizes, configurations and spacings to efficiently and effectively deliver a pressurized, high velocity, laminar flow air stream to dry, cool, or clean objects that are either stationary or moving transversely through the optimized air stream developed by the apparatus, all while minimizing the operational downtime required to implement the interchangeable nozzle insert modifications to the apparatus.
Abstract:
The present disclosure provides a method of fabricating a semiconductor device. The method includes dispensing a liquid on a wafer. The method includes raising the wafer. The method includes lowering the wafer after the raising. The wafer is spun as it is lowered, thereby removing at least a portion of the liquid from the wafer. The present disclosure also provides an apparatus for fabricating a semiconductor device. The apparatus includes a wafer chuck that is operable to hold a semiconductor wafer and secure the wafer thereto. The wafer has a front surface and a back surface. The apparatus includes a dispenser that is operable to dispense a liquid to the front surface of the wafer. The apparatus includes a mechanical structure that is operable to: spin the wafer chuck in a horizontal direction; and move the wafer chuck downwards in a vertical direction while the wafer chuck is being rotated.

Abstract:
A thermal grease smearing apparatus includes a platform for placing a heat sink, a supporting post projecting from the platform, and a bracket mounted to the supporting post. The bracket includes a bottom plate with a smearing hole. A thermal grease pipe is mounted to the bracket and includes a pipe body having an upper opening for introducing thermal grease and a lower opening for applying the thermal grease onto a bottom surface of the heat sink. When the bracket is positioned in a working position, the bottom surface aligns with a the smearing hole and abuts a lower surface of the bottom plate, a smearing portion contacts with the thermal grease applied onto the bottom surface and is actuated to rotate about a central axis of the thermal grease pipe thereby smearing the thermal grease uniformly spread on the bottom surface of the heat sink.

Abstract:
An apparatus for forming phosphor layers on a display panel includes a base plate on which a display panel is placed. The base plate is inclined at an adjustable angle. The display panel, having a panel plate and barrier ribs formed on the panel plate is placed on the base plate. A spray unit includes a nozzle assembly for spraying a slurry containing phosphors into spaces between the barrier ribs. A charged unit for exerting electrostatic force on the phosphors is positioned adjacent to the display panel. The apparatus enables rapid formation of uniform phosphor layers on a display panel with the phosphor particles located adjacent to the surfaces of the phosphor layers.
Abstract:
It is possible to give ultrathin and uniform coating on a flexible web in scraping-off type coating. The distribution of pressure in a web width direction is adjusted by a pressure distribution adjusting device when an excess of coating liquid excessively applied is scraped off by a doctor blade by giving relative pressure to a coating surface of a web and the doctor blade after applying the coating liquid that is more excessive than the desired quantity of the coating liquid on the web by a precoating apparatus while making the web continuously travel.
Abstract:
The object of the invention is a device for applying a thin layer of a powder on support means (14) comprising means (12) for storing the powder, screeding means (16) with a screed (30) comprising a shoe (36) with a working surface as well as means (28) for guiding in translation in a direction of movement F, characterized in that the shoe (36) is rotatable and comprises means (32, 34) for inclining it to take at least two positions, the first in which the working surface is parallel to the support means (14) for the layers to take up a predetermined volume of powder and a second in which this working surface is inclined at an angle null relative to said support means.
Abstract:
An applying apparatus includes an applying unit for applying a photoresist to a semiconductor wafer on the basis of an applying condition, a thickness measuring unit for measuring the film thickness of the photoresist applied, and a control unit for controlling the applying unit. On the basis of information on the applying condition for a predetermined number of samples and information on the film thickness on the predetermined number of samples, the control unit plots an approximate curve that indicates the relation between the film thickness and the applying condition of the predetermined number of samples. When the applying apparatus starts its actual operation, the control unit calculates a correction value of the applying condition from a thickness target value on the basis of the plotted approximate curve, and generates a control signal for controlling the applying condition on the basis of the calculated correction value.
Abstract:
The present invention relates to methods and apparatus for the controlled placement of a shear-thinnable polymer composition into a moving web. The controlled placement is preferably performed by applying the polymer composition onto a surface of a moving web, shear thinning the composition and placing it into the web, and curing the polymer composition. A preferred apparatus includes one or more process heads that has mounted thereto a rigid knife blade for engagement with the moving web. The knife blade is movable vertically and rotationally. The process head is also movable horizontally along the path of the moving web. A plurality of macro and micro tension zones are established and are monitored for controlling the apparatus and process. Additional measurements of web density, micro porosity, placement of an internal layer of polymer within the web, analysis of elements on the treated web, and the size of the polymer bead applied to the moving web are measured for controlling online the apparatus and the process of this invention. This method and apparatus produces webs that either has some of its structural elements encapsulated by the polymer composition while at least some of the interstitial spaces of the web are open; or has an internal layer extending through the web in a direction generally spaced from at least one major surface thereof; or has both encapsulated structural elements and an internal layer of polymer composition.
