RF Devices Integrated by Fan-Out and System-In-Package Technology

Higher performance and smaller form factor are always the critical subjects for mobile device in recent years. To meet this demand, System-In-Package (SiP) has become a certain path for innovation and an unstoppable trend for decade. In this study, the benefits of evolving SiP with organic substrate to Fan-Out SiP (FOSiP) for new generation mobile RF module with higher performance and smaller form factor has been illustrated. A designed and manufactured FOSiP module with 6 RF devices integrated by several core features and building blocks would be demonstrated, including chip-last RDL manufacturing, carrier system, wafer level assembly and shielding sputtering.
