  • Publication number: 20230199923
    Abstract: A microwave treatment device according to one aspect of the present disclosure includes a heating chamber, a microwave generator, an amplifier, a feeder, a detector, a controller, and a storage. The microwave generator generates a microwave having an arbitrary frequency in a predetermined frequency band. The amplifier amplifies the microwave and outputs the amplified microwave as incident microwave power. The feeder supplies the incident microwave power to the heating chamber. The detector detects the incident microwave power and reflected microwave power that returns from the heating chamber to the feeder. The storage stores the incident microwave power and the reflected microwave power in association with the frequency of the microwave and time elapsed since the start of heating. The controller causes the microwave generator to execute a frequency sweep over the predetermined frequency band.

  • Publication number: 20230052961
    Abstract: The high-frequency treatment device according to one embodiment of the present disclosure includes: a heating chamber that accommodates a heating target; an oscillator; at least one feeder; a detector; and a controller. The oscillator generates high-frequency power having an arbitrary frequency in a predetermined frequency band. At least one feeder supplies incident microwave power based on the high-frequency power to the heating chamber. The detector detects the incident microwave power and reflected microwave power returning from the heating chamber to at least one feeder. The controller causes the oscillator to execute a frequency sweep and measures a reflection characteristic based on the incident microwave power and the reflected microwave power for each heating condition including a frequency. The controller determines, based on a reflection variation range indicating a change in the reflection characteristic for each heating condition, a heating condition to be used next.

  • Publication number: 20230047831
    Abstract: This high-frequency treatment device includes: a heating chamber configured to accommodate a heating target; a high-frequency power generator; a feeder; a detector; a controller; and a storage. The high-frequency power generator generates high-frequency power having a frequency in a predetermined frequency band. The feeder supplies incident microwave power corresponding to the high-frequency power to the heating chamber. The detector detects at least one of the incident microwave power and reflected microwave power that is included in the incident microwave power and returns from the heating chamber to the feeder. The controller controls heating of the heating target by controlling the high-frequency power generator. The storage stores, together with time elapsed from the start of heating, information detected by the detector. The controller causes the high-frequency power generator to repeatedly generate, on a per frequency basis, the high-frequency power having a plurality of frequencies for the heating.

  • Publication number: 20220308430
    Abstract: A light source apparatus includes an excitation light emitter configured to irradiate excitation light, a phosphor that receives the excitation light and converts the excitation light into wavelength band light different from the excitation light, and a color wheel device. A first region of regions divided in a radial direction of the color wheel device includes a first transparent part that transmits the wavelength band light. A second region, which is different from the first region of the regions divided in the radial direction of the color wheel device, includes a reflector that reflects the excitation light and changes a light path and a second transparent part that transmits the excitation light. The phosphor is arranged on a light path of the excitation light reflected by the reflector or on a light path of the excitation light transmitted by the second transparent part.

  • Patent number: 11259415
    Abstract: In conventional fluid discharge devices, a discharge head used should be increased in size according to increase in size of a workpiece such as silicon wafer. However, if the discharge head increases in length, a deformation amount of a mask used for discharging the fluid on the workpiece increases, thereby the discharging amount varies. Discharging the fluid in a reciprocating manner is performed using a fluid discharging device including a head unit having a width shorter than a length of the workpiece. A suction port having opening portions each having a slit shape are disposed on the both sides of the discharge nozzle in a vicinity of the discharge nozzle.

  • Patent number: 10681822
    Abstract: A pattern formed on a silicon wafer is fine so that solder bumps formed on the silicon wafer are also fine and hence, when a failure occurs, the failure cannot be corrected so that an entire silicon wafer as a workpiece is discarded. Provided is a correction method where, on solder bumps formed on the silicon wafer, a mask in which holes are formed with the same pattern as the solder bumps is placed so as to cover the solder bumps and, thereafter, molten solder is caused to come into contact with the solder bumps through the mask thus filling hole portions of the mask with the molten solder.

  • Patent number: 10632492
    Abstract: A defect may occur in which as the amount of fluid discharged by a fluid discharge device decreases, a mask is not filled with the fluid even when the fluid is discharged. In order to fill a workpiece with the fluid, it is necessary to replace air in the workpiece corresponding to a discharge part with the fluid. The air in the workpiece is removed in advance, thereby filling the workpiece with the discharged fluid. A fluid discharge device in which, at one end of a discharge head, a suction port for sucking air in the mask on the workpiece, and a fluid discharge device having a discharge nozzle formed thereon for discharging the fluid are formed is used.
