Abstract

Using laser scanning confocal microscopy measurement, a concise method for extracting the indium bump shape in microelectronics was first established. The extracted bump shape was then used as the input for finite element analysis. The modeled one-bump deformation was used to predict the final flip–chip gap after bonding. Dovetailed with the results of cross-sectional scanning electron microscopy, this simple and non-destructive method for predicting a flip–chip gap of the order of 10 microns or less was eventually validated.

一个简单的方法来预测倒装芯片的间隙

利用激光扫描共聚焦显微镜测量，首次建立了一种在微电子技术中提取铟凸块形状的简明方法。提取的凸起形状然后被用作有限元分析的输入。模型化的单凸块变形用于预测键合后的最终倒装芯片间隙。随着横截面扫描电子显微镜的结果，这种预测10微米或更小数量级倒装芯片间隙的简单无损方法最终得到了验证。
