A flexible display substrate and a method for manufacturing the same are provided. The method includes: forming a first insulating layer on a flexible base substrate; forming an etching barrier layer on a side of the first insulating layer away from the flexible base substrate; forming a second insulating layer covering the etching barrier layer on the side of the first insulating layer away from the flexible base substrate; and forming a first opening in the first insulating layer and a second opening in the second insulating layer through one patterning process, so that an orthographic projection of the first opening on the flexible base substrate falls within an orthographic projection of the second opening on the flexible base substrate, so as to form a step portion at a connection position where the first opening is connected to the second opening.

A technique for providing information about defects in a mask pattern is described. In this technique, defects in the mask pattern may be determined based on differences between a calculated pattern produced at an image plane in the photolithographic process, when the mask pattern, illuminated by an associated source pattern, is at an object plane in the photolithographic process, and a target pattern that excludes the defects. Then the defect information may be provided to the user, such as a spatial map of the determined defects, where the spatial map is associated with at least the portion of the mask pattern.
