一种2.5D、3D封装中的玻璃载板开窗及双面金属化工艺
技术领域
本发明涉及晶片生产领域,具体的是一种2.5D、3D封装中的玻璃载板开窗及双面金属化工艺。
背景技术
随着人类生活品质的提高,随身携带多样性的发展,最终产品需依轻,薄、小、快的规格发展,近年来,在封装技术上,已从传统的引线连接晶粒再连接印刷电路板的方式,发展到2.5D及3D的封装技术。“穿透硅通道(Through-Silicon Vias)”技术的成熟化,使得可以上下多层堆叠,凸块技术解决了上下层堆叠中互连需求。与传统的引线键合互联封装相比,硅通孔技术加上凸块技术连接,有导电好,功耗低及封装体积小的优点。
在生产过程中,一般采用铜为通孔及重布线的材料,完成晶圆正面凸块电镀工序后,实行包覆凸块工艺,再用玻璃载板键合,使得键合后可以薄化晶圆(20-200um),依序完成另外一面的重布线工艺后,再实行晶圆另外一面凸块的电镀工序,解键合,去除凸块的包覆,再后续工序。
为了薄化各层晶圆厚度,以达到最终多层堆叠的厚度极小化及导电好及功耗低的优点,需键合玻璃载板,实行晶圆薄化工序,键合玻璃载板,这键合的玻璃只有支撑键合后研磨薄化晶圆的功能。
