This standard specifies the preparation, analysis procedures, analysis methods, and processing of analysis results before failure analysis of semiconductor integrated circuits
1.2 Scope of Application
This standard is applicable to semiconductor integrated circuits (hereinafter referred to as devices). 1.3 Application Guidelines
This standard specifies three different levels of analytical procedures and methods that can be used in the laboratory. Failure analysis personnel should choose the corresponding analysis program and method based on factors such as device model, packaging form, reliability level, and requirements of the commissioning unit

3.1 Defects
Any inconsistency with the detailed technical specifications in terms of appearance, assembly, function, or process quality.
. 3.2 Screenable defectsDefects that can be eliminated using effective screening methods. 3.3 Batch defects Lot related defects
Defects caused during the design and manufacturing process and repeated multiple times in the same batch of devices (such as: thickness of metallization layer, bonding strength, insulation material performance, metallization wiring, improper spacing between bonding leads, and between bonding leads and chip edges, or mask defects)
3.4 Failure Mode
The manifestation of device failure.
3.5 Failure mechanismFunction of testing report:
1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report
2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms 3. Used as a sales report: issuing legally effective testing reports to make consumers more confident 4. Papers and research: Provide professional personalized testing needs 5. Judicial services: providing scientific, fair, and accurate testing data 6. Industrial problem diagnosis: Verify the troubleshooting and correction of industrial production problemsBaijian and testing process:
1. Telephone communication and confirmation of requirements
2. Recommend solutions and confirm quotations 3. Mail samples and arrange testing 4. Progress tracking and result feedback 5. Provide reports and after-sales service 6. If urgent or priority processing is requiredTesting and testing characteristics:
