Semiconductor AOI Production Inspection
行业概况
AOI Is Critical in Semiconductor Manufacturing
Automated optical inspection is widely used in semiconductor manufacturing because visual defects can appear across many process stages.
Inspection may be required during wafer processing, die handling, substrate preparation, bonding, 包装, 标记, and final product verification.
Common AOI targets include:
- Wafer surface defects
- Die alignment errors
- Particle contamination
- Pattern abnormalities
- Package cracks
- Substrate defects
- Lead frame defects
- Bonding area issues
- Marking and code defects
- Final appearance abnormalities
A semiconductor AOI platform helps manufacturers identify these defects earlier and connect inspection results with production records.
Inspection Data Supports Yield Improvement
AOI is not only used to reject defective units.
It also generates valuable data for yield analysis, process tuning, equipment monitoring, and quality improvement.
Manufacturers may need to record:
- 缺陷类型
- Defect location
- Wafer ID
- Die coordinates
- Lot number
- Package ID
- Inspection image
- 站号
- 设备状态
- 时间戳
When this data is collected consistently, engineering teams can identify recurring defects, 过程漂移, and equipment-related quality issues.
