3D packaging is definitely one of the hottest research topics in semiconductor industry. Three kinds of 3D packaging, i.e., wire bonding (WB), package-on-package (PoP) and through-silicon-via (TSV), have been developed to meet the miniaturization requirements of electronics products. Since 3D packaging is a multi-layered materials bonded complicated system, the packaging industry encounters more and more manufacturability & reliability issues in the development of 3D packages. In this project, based on the knowledge of reliability engineering established for 2D packaging in last decade and the database built for 3D packaging in past few years, a virtual 3D-packaging design advisor, which consists of two key components of virtual manufacturing and virtual reliability assessment and a full set of design for manufacturability (DFM) and design for reliability (DFR) guidelines, will be developed and applied to address the manufacturability and reliability issues in PoP and TSV packages. As a result, a new PoP package and a new TSV package will be developed and demonstrated for 3D system integration. The success of this project can not only promote Hong Kong and China’s microelectronics packaging industry to an advanced position but also enhance the industry’s competitiveness through shortening time-to-market and adopting new packaging technologies.
