Design and implementation of ultra-thin SiP modules

In recent years, SiP (System-in-Package) or SOP (System on Package) technology has become an attractive solution for size reduction of mobile devices. Passive components such as inductors or capacitors can be integrated into the substrate. The dimension of embedded capacitors can be further reduced by using high dielectric constant material. Thus, size miniaturization and cost reduction can be easily achieved through the replacements of surface-mounted devices (SMDs) on the substrate.chip can be reduced. Wafer-level packaging technology, wafer thinning technology, buried ultra-thin chips technology, and embedded passive components technology are both integrated in this paper to achieve a miniaturized ultra-thin SiP module. The feasibility of the ultra-thin SiP technology was verified by using a GPS module. For high integration and flexible design, an eight-layered organic substrate process is used in this project.
