... for future IC packaging. However, Cu filling of void free through silicon via with high aspect ratio (AR≥10) has been a challenge for a long time. In this paper, successful fabrication of void free TSV with very high aspect ratio was demonstrated via electroplating process. Proper equipment and processing...
