摘要

测试车辆(tv)的开发是为了检查AOI(自动光学检测)系统的大批量生产(HVM)准备情况,该系统支持检测为高带宽应用而设计的细间距先进基板。本研究证明了现有检测系统的缺陷检测能力。数据的广泛可变性表明,在特征边缘检测方面需要一些改进。此外,一些AOI系统能够对低至4um的走线宽度/空间进行HVM检查,并具有1um级别的缺陷。

Fine Pitch Circuit Pattern Inspection Capability Study for Fan-out Wafer/Panel Level Packaging
Test Vehicles (TVs) were developed to examine the high-volume manufacturing (HVM) readiness of AOI (Automated Optical Inspection) systems supporting the inspection of fine pitch advanced substrates designed for high bandwidth applications. This study demonstrated the capability of defect detections with current inspection systems. The wide variability of the data suggests that some improvements are desired in feature edge detections. Additionally, some of the AOI systems are capable of HVM inspection down to 4 um trace width/spaces with 1um level defects.
