  • Publication number: 20240079214
    Abstract: A surface modifying method of modifying a bonding surface of a substrate to be bonded to another substrate by plasma of a processing gas includes an adjusting process and a modifying process. In the adjusting process, an amount of moisture in a processing vessel is adjusted by supplying a humidified gas into the processing vessel allowed to accommodate the substrate therein. In the modifying process, the bonding surface of the substrate is modified by forming the plasma of the processing gas in the processing vessel in a state that the amount of moisture in the processing vessel is adjusted.

  • Patent number: 11133176
    Abstract: In a substrate processing method, as a liquid film forming process, a liquid film of a processing liquid covering a surface of a substrate W is formed by supplying the processing liquid onto the surface of the substrate W while rotating the substrate W at a first rotation number. After the liquid film forming process, as a supply stopping process, a rotation number of the substrate W is set to be of a value equal to or less than the first rotation number and a supply of the processing liquid onto the substrate W is stopped. After the supply stopping process, as a liquid amount adjusting process, a liquid amount of the processing liquid forming the liquid film is reduced by setting the rotation number of the substrate W to a rotation number larger than the first rotation number.

  • Patent number: 10504718
    Abstract: During at least part of a time period for a pressure increasing step of increasing a pressure inside a processing container from a pressure lower than a critical pressure of a processing fluid to a pressure higher than the critical pressure, pressure increasing is performed by supplying the processing fluid into the processing container from a fluid supply source while discharging the processing fluid from the processing container at a controlled discharge flow rate. Particles attached to the surfaces of members inside the processing container travel upward by the supply of the processing fluid into the processing container from the fluid supply source. The particles are discharged along with the processing fluid from the processing container.

  • Patent number: 10261521
    Abstract: Disclosed is a processing apparatus including a chamber, at least one nozzle, a measuring unit, an opening/closing unit, and a controller. The chamber accommodates a workpiece therein. The nozzle is provided in the chamber to supply a processing fluid toward the workpiece. The measuring unit measures a supply flow rate of the processing fluid supplied to the nozzle. The opening/closing unit performs opening/closing of a flow path of the processing fluid to be supplied to the nozzle. The controller outputs opening and closing operation signals at a preset timing. After outputting the opening operation signal, the controller calculates an integrated amount of the processing fluid based on a measurement result of the measuring unit, and performs an output timing change processing to change a timing of outputting the opening or closing operation signal from the preset timing based on the calculated integrated amount.
