  • Publication number: 20220238346
    Abstract: In order to improve the quality of a substrate, a substrate processing apparatus includes a substrate holding unit, a first drive unit, a chemical liquid discharge portion, a cup unit, a second drive unit, and a control unit. The substrate holding unit holds a substrate having a first surface and a second surface opposite to the first surface in a horizontal posture. The first drive unit rotates the substrate holding unit about a virtual axis. The chemical liquid discharge portion discharges a chemical liquid toward the first surface of the substrate held by the substrate holding unit. The cup unit surrounds a periphery of the substrate holding unit. The second drive unit changes a relative position in the vertical direction of the cup unit with respect to the substrate holding unit.

  • Publication number: 20220148896
    Abstract: A processing condition selection method includes a step (S21) and a step (S22). In the step (S21), a thickness pattern TM that represents a distribution of thicknesses measured at respective measurement points on a target is compared to pre-stored reference patterns (RP) to specify a reference pattern (RP) having a high correlation with the thickness pattern (TM) from among the reference patterns (RP) based on a prescriptive rule. In the step (S22), a reference processing condition associated with the specified reference pattern (RP) is acquired as a processing condition for the target from among reference processing conditions associated with the respective reference patterns (RP). The reference patterns (RP) each represent a distribution of physical quantities of a corresponding one of reference targets.

  • Patent number: 11031235
    Abstract: A substrate processing apparatus includes a driving magnet that is disposed correspondingly to a movable pin and that has a predetermined polar direction with respect to a radial direction of a rotary table, a pressing magnet that has a magnetic pole that gives an attractive magnetic force or a repulsive magnetic force between the driving magnet and the pressing magnet and that presses a support portion against a peripheral edge of a substrate by urging the support portion toward a contact position by means of the attractive magnetic force or the repulsive magnetic force, and a pressing-force changing unit that changes a magnitude of a pressing force against the peripheral edge of the substrate pressed by the support portion while keeping the magnitude higher than zero in response to rotation of the rotary table.

  • Patent number: 10854479
    Abstract: A substrate processing method is provided, which includes: an ozone-containing hydrofluoric acid solution spouting step of spouting an ozone-containing hydrofluoric acid solution containing ozone dissolved therein from a nozzle toward one major surface of a substrate held by a substrate holding unit; and a brush-cleaning step of cleaning the one major surface of the substrate by bringing a cleaning brush into abutment against the one major surface of the substrate, the brush-cleaning step being performed after the ozone-containing hydrofluoric acid solution spouting step or in parallel with the ozone-containing hydrofluoric acid solution spouting step.

  • Patent number: 9805938
    Abstract: A substrate processing apparatus includes a rotating holder for a substrate, a first nozzle used to eject a jet flow, a second nozzle used to discharge a continuous flow, and a nozzle moving unit integrally moving the first and second nozzles. A landing position of the continuous flow is located closer to a rotation center than a landing position of the jet flow is. At least movement paths of the landing positions of the jet flow and the continuous flow or flow directions of the continuous flow and the jet flow are different from each other. The movement paths are made to be different from each other by locating the landing position of the continuous flow downstream of the movement path of the landing position of the jet flow. The flow directions are made to be different from each other by tilting the continuous flow.
