1)chip first 是指先制备好芯粒,将其放于不同形式的Carrier 上,然后再制备RDL层,最后贴焊锡球. 2)而Chip last 是先将RDL制备好,然后贴装芯粒,塑封最后再贴 焊锡球. 2,HDFO (High-Density Fan-Out) HDFO高密度扇出,这个概念对应的就有Fan-In。 两者最大的差异为RDL布线,在扇入型封装中,RDL向内布线,而在扇出型封装中,RDL既可向内又可向外布线,所以扇出型封装可以实现更多的I/O。 3, Interposer. Interposer中文叫 中介层。 它利用硅通孔技术TSV,

To address these challenges, a new interposer-PoP with High-Density Fan-Out (HDFO) redistribution layer (RDL) routing layer has been designed and demonstrated. It is part of an initiative to achieve an ultra-thin package z-height, interposer-PoP structure with high bandwidth and improved signal integrity/power integrity (SI/PI) routing layer ...
Organic Damascene Process for 1.5- - IEEE Xplore
2018年4月19日 · Abstract: This paper presents a novel organic embedded trace damascene redistribution layer (RDL) process for panel-scale 2.5-D interposers and high-density fan-out package (HDFO) substrates. A minimum feature size of 1.5- μm line and space using ultrathin polymer dielectrics on glass, silicon, and as well as on organic laminate was demonstrated.
