Abstract(in English) | We have successfully developed a novel Package-on-Package (PoP) technology for achieving small package thickness and low package warpage. The novel package structure is based on an ultra-thin coreless substrate, called a Multi-Layer Thin Substrate (MLTS). MLTS has considerable advantages over a conventional build-up PWB, especially for operation in the GHz range. The MLTS is fabricated by completely removing the Cu base plate after forming a high-density build-up structure on the base plate. In this paper, however, the Cu posts of 0.5 mm pitch and 125 μm height are formed by selective wet etching of the Cu base plate. If the MLTS has built-in Cu posts as external terminals, the overall substrate can be molded with an appropriate resin for the peripheral area as well as the chip mounting area. Therefore, the novel package can be expected to realize low warpage. |
