Description
Marking information detection method, device, system, storage medium and electronic equipment Technical Field The present invention relates to the field of semiconductors, and in particular, to a method, apparatus, system, storage medium, and electronic device for detecting marking information. Background In the production process of the semiconductor device, the laser marking process plays a key role in marking product information (such as a chip model number, a batch number, performance parameters and the like), and the accuracy of marking information is directly related to quality control, circulation tracing and market acceptance of the product. In the laser marking process, marking content is easy to be inconsistent with process requirements, and quality and traceability of products are affected. In order to solve the problem, currently, manual comparison of marking preview content and production files is adopted in a visual inspection mode, so that the condition that marking content is inconsistent with technological requirements easily is avoided. However, by manually comparing the content of the previews of the mark with the process production file, a comparison error inevitably occurs, thereby affecting the production efficiency.
