  • Publication number: 20240009769
    Abstract: A joining apparatus includes a table, a pressurizing mechanism, a laser light source that emits laser light, and a controller. The table has permeability to the laser light. Two joining targets are to be placed on the table while a first metal layer and a second metal layer face each other. The pressurizing mechanism includes a diaphragm, and is capable of applying pressure to a back surface of the joining target using the diaphragm from an opposite side to the table. The controller brings the first metal layer and the second metal layer into contact with each other by applying pressure to the back surface of the joining target while the two joining targets are placed on the table, and while maintaining the resultant state, applies the laser light to a place of contact between the first metal layer and the second metal layer through the table.

  • Patent number: 9016235
    Abstract: The substrate coating device (10) includes a slit nozzle (1), a first camera (3), a second camera (4), a control section (5), a pump (8), and a pressure control chamber (9). The control section (5) controls the supply of the coating liquid from the pump (8) to the slit nozzle (1) in accordance with the result of comparison between a bead shape imaged by the first camera (3) and a reference shape. The control section (5) also controls the air pressure on the upstream side of the slit nozzle (1) by the pressure control chamber (9) in accordance with the result of comparison between a distance measured from an image taken by the second camera (4) and a reference distance.

  • Patent number: 8980114
    Abstract: A film in a dry state is efficiently dissolved and removed. A film removing method includes steps of moving a nozzle head (10B) close to a soluble film (201) formed on a substrate (200), forming a liquid pool (302) of chemical liquid (300) between the nozzle head (10B) and the film (201) by continuously and simultaneously discharging and sucking the chemical liquid (300) from the nozzle head (10B), and horizontally moving the substrate (100) in a state in which the nozzle head (10B) and the surface of the film (201) are not contacted so as to relatively move the liquid pool (302) of the chemical liquid on the substrate (100).

  • Patent number: 8770141
    Abstract: A substrate coating device is provided which is capable of reducing non-uniform film thickness areas that take place in a coating start portion and a coating end portion during coating using a slit nozzle coater. The substrate coating device (10) includes at least a slider driving motor (4), a pump (8), a delivery state quantity measuring section (82), and a control section (5). The slider driving motor (4) scans a slit nozzle (1) over a substrate (100) at an established velocity relative to the substrate (100). The pump (8) controls the supply of the coating liquid to the slit nozzle (1). The delivery state quantity measuring section (82) is configured to measure a state quantity indicative of a delivery state of the coating liquid from the tip of the slit nozzle (1).

  • Publication number: 20140186537
    Abstract: A method for controlling a flow rate of a pump (10) transporting a liquid being driven by a drive system having a sliding portion, wherein a flow rate is maintained at a minute first flow rate (R1) at an early stage of operation of the pump (10); and subsequently the flow rate is increased to a steady second flow rate (R). With the method, at the early stage of operation of the pump (10), a state is established beforehand in which the pump (10) is kept stable at the minute first flow rate in order for the stick-slip phenomenon not to occur; and because the flow rate of the pump is increased from the state, transition from static friction to kinetic friction does not occur; and thus a disorderly flow rate of the pump (10) due to the stick-slip phenomenon of a motor (12) is suppressed. This makes it possible to attain a stable control of the flow rate at the early stage of operation of the pump (10).

  • Publication number: 20130252432
    Abstract: Provided is a patterning method that can greatly reduce process costs and environmental load. The patterning method includes: a film forming step of forming a functional film (2) on a substrate (1) ; and an etching step of irradiating the substrate with vacuum ultraviolet light (12) from above a mask (4) that is placed on the functional film (2) and has an arbitrarily-defined opening (4A) so as to dry etch the functional film (2) positioned below the opening (4A). The dry etching step can be carried out in an atmosphere containing oxygen. For example, dry air can be used as process gas. In addition, N2 may be supplied as an inert gas to the substrate (1) placed in the atmosphere.
