  • Patent number: 11194254
    Abstract: Techniques for lithography process delay characterization and effective dose compensation are provided. In one aspect, a method of analyzing a lithography process includes: applying a photoresist to a wafer; performing a post-apply bake of the photoresist; patterning the photoresist with sequences of open frame base line exposures performed at doses of from about 92% E0 to about 98% E0, and ranges therebetween, at multiple fields of the wafer separated by intervening programmed delay intervals, wherein E0 is the photoresist dose-to-clear; performing a post-exposure bake of the photoresist; developing the photoresist; performing a full wafer inspection to generate a grayscale map of the wafer; and analyzing the grayscale map to determine whether the intervening programmed delay intervals had an effect on the open frame base line exposures during the lithography process. Exposure dose compensation can then be applied to maintain a constant effective dose.

  • Patent number: 11182722
    Abstract: A method includes monitoring with at least one monitoring tool one or more activities associated with an enterprise. The method further includes analyzing data input from the at least one monitoring tool of the one or more activities, and determining, based on analytics performed on the data input and an implemented policy, when the one or more activities qualifies as an incident. A remedial response responsive to the incident is initiated. The monitoring, analyzing, determining and initiating steps are performed by at least one processing device including a processor operatively coupled to a memory.

  • Patent number: 11067896
    Abstract: A method of optimizing a lithographic process for semiconductor fabrication includes determining that a semiconductor wafer experienced a photoresist exposure delay. At least one operating parameter of a post exposure baking process is adjusted based on the semiconductor wafer having experienced the photoresist exposure delay. The post exposure baking process is performed on the semiconductor wafer utilizing the adjusted at least one operating parameter.
