SIP封装技术全景解析
System-in-Package Technology Overview
技术定义
SIP(系统级封装)通过三维异构集成将多工艺芯片(Si/GaAs/InP)、无源器件、MEMS及光学元件整合于单一封装,实现完整子系统功能。相较于SoC,SIP以更短周期(缩短40%)、更低成本(降低30%)、更高灵活性突破摩尔定律限制。

System-in-Package Advanced Integration
Technology Definition
SIP (System-in-Package) enables 3D heterogeneous integration of multi-process chips (Si/GaAs/InP), passives, MEMS, and optoelectronics into single package. Compared to SoC, SIP delivers shorter cycles (40% faster), lower cost (30% reduction), and superior flexibility beyond Moore's Law.
