  • Publication number: 20250174486
    Abstract: When a substrate is held by a first hand, a servomotor is operated to move each guide to an outer peripheral surface of the substrate. When a tactile sensor detects that each guide abuts on the outer peripheral surface of the substrate, the servomotor adjusts a biasing force by each guide to the outer peripheral surface of the substrate according to the shape of the substrate. Therefore, the grasping force can be adjusted according to the shape of the substrate such as warpage and a thickness of the substrate. As a result, it is possible to prevent the substrate from being damaged during transportation regardless of the shape of the substrate.

  • Patent number: 12142502
    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.
