Publication number: 20230052961Abstract: 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.Type: ApplicationFiled: January 26, 2021Publication date: February 16, 2023Inventors: YOSHIHARU OOMORI, DAISUKE HOSOKAWA, HIDEKI NAKAMURA, KAZUKI MAEDA, TAKASHI UNO

Publication number: 20230047831Abstract: 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.Type: ApplicationFiled: February 16, 2021Publication date: February 16, 2023Inventors: HIDEKI NAKAMURA, DAISUKE HOSOKAWA, YOSHIHARU OOMORI, KAZUKI MAEDA, TAKASHI UNO

Patent number: 11259415Abstract: 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.Type: GrantFiled: January 21, 2021Date of Patent: February 22, 2022Assignee: SENJU METAL INDUSTRY CO., LTD.Inventors: Hideki Nakamura, Takashi Nauchi, Toshihiko Mutsuji, Ryoichi Suzuki

Patent number: 10681822Abstract: 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.Type: GrantFiled: December 15, 2016Date of Patent: June 9, 2020Assignee: SENJU METAL INDUSTRY CO., LTD.Inventor: Hideki Nakamura

Patent number: 10632492Abstract: 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.Type: GrantFiled: January 13, 2016Date of Patent: April 28, 2020Assignee: SENJU METAL INDUSTRY CO., LTD.Inventors: Takashi Nauchi, Hideki Nakamura, Toshihiko Mutsuji, Kazuya Kitazawa
