  • Publication number: 20260072358
    Abstract: The present application discloses a mask pattern determination method, apparatus, medium, and program product, which are applied to the technical field of semiconductor. In the mask pattern determination method provided in the present application, a target mask pattern is determined based on a plurality of second sampling points, and the second sampling points are obtained by performing etching bias correction on a first sampling point based on a first etching deviating data between a position corresponding to a first sampling point on the first photolithography pattern and a position corresponding to the first sampling point on the first etch pattern. The first sampling point may represent a pattern contour of the first target etch pattern. Therefore, in the present application, an etching bias of a curved contour may be corrected relatively accurately by correcting the plurality of sampling points individually.

  • Patent number: 11975988
    Abstract: The determination of hydroxyl radical scavenging capacity of contaminated water can be achieved by developing an external calibration model. The model can be prepared using standard solutions where scavenging capacities are determined, and then the solutions are treated with addition of an oxidant and a dye, followed by UV treatment to form hydroxyl radicals that are scavenged by species in the standard solution. The residual dye content can then be measured using absorbance. The absorbance and the scavenging capacity data for the standard solutions are used to build the model, which can then be implemented to determine scavenging capacity of contaminated water. Water samples can be subjected to the same treatment as the standard solutions, the absorbance of the water sample is then obtained, and then the model is used to determine the corresponding scavenging capacity. Determining scavenger capacity of contaminated water can aid in advanced oxidation processing (AOP).
