  • Patent number: 11988969
    Abstract: The present application relates to a dispatch method for a production line in a semiconductor process, a storage medium and a semiconductor device. The dispatch method for a production line in a semiconductor process can acquire an overlay error reference curve of a product lot to be exposed in equipment and set an overlay error range according to the overlay error reference curve. At the end of exposure, an overlay error for the product lot to be exposed can be acquired, and it can be determined whether the overlay error falls into the overlay error range. If the overlay error for the product lot to be exposed does not fall into the overlay error range, the product lot to be exposed can be continuously machined by this equipment.

  • Publication number: 20240151103
    Abstract: An adjustable resistance tail plug includes a fixed seat, an adjusting wheel, a sleeve, a screw rod unit, an outer casing, a friction wheel and a clutch spring. The friction wheel engages threadably the screw rod unit, and is driven by the sleeve to move relative to the outer casing, so as to adjust a friction force between the outer casing and the friction wheel. The clutch spring is switchable between a contracted state and an expanded state. When in the contracted state, the clutch spring is tightened to abut against the second circumferential surface so that the sleeve is prevented from rotating relative to the fixed seat by the clutch spring. When in the expanded state, the clutch spring releases the second circumferential surface, and the adjusting wheel is rotatable with the sleeve through the clutch spring.
