具体实施方式
下面将结合附图,对本申请中的技术方案进行描述。
首先对本申请实施例中涉及以下专业术语做介绍。
1、三维(three dimensional,3D)堆叠
3D堆叠技术是把不同功能的芯片或结构,通过堆叠技术或过孔互连等微机械加工技术,使其在Z轴方向上形成立体集成、信号连通及圆片级、芯片级、硅帽封装等封装和可靠性技术为目标的三维立体堆叠加工技术。
2、硅通孔(through silicon via,TSV)
TSV是3D芯片堆叠技术的关键三维芯片允许多层堆叠,而过TSV用来提供多个晶片垂直方向的通信。其中,TSV是利用垂直硅通孔完成芯片间互连的方法,由于连接距离更短、强度更高,它能实现更小更薄且性能更好、密度更高、尺寸和重量明显减少的封装,同时还能用于异种芯片之间的互连。TSV通过在芯片与芯片之间、晶圆与晶圆之间制作垂直导通,实现芯片之间互连,能够使3D芯片堆叠的密度最大,外形尺寸最小,并且大大改善芯片速度和降低功耗。
3、倒装焊接(flip chip,FC)
倒装焊接是指在芯片的输出/输出(input/output,I/O)焊盘(pad)上沉积锡铅球,然后将芯片翻转加热利用熔融的锡铅球与基板相结合。
4、重布线层(Redistribution Layer,RDL)
