International Technology Roadmap for Semiconductors(ITRS)国际半导体技术发展路线图的预测 SOC和SOP、SIP SoC：System-on-Chip（片上系统）:A SoC is a VLSI system that utilizes a large number of transistors to incorporate several kinds of function blocks into a single chip（把不同的功能模块集成到一个芯片中）, which offers the most compact and light-weight design SiP：System-in-Package（内封装系统）:SiP provides an alternative way to improve system performance and decrease power consumption, while solving some problems faced by SoC [3][8]. Instead of incorporating all the function blocks into one chip, a SiP contains multiple chips combined into a single package（一个封装包含多个芯片）, whose dimension is typically on the same order of magnitude as one chip’s package. SoP：System-on-Package（全集成封装系统）， is a new concept of SiP, which utilizes thin film technology to combine passives into the package（利用薄膜技术把无源元件嵌入到封装中）. RF-SOP is “to provide a complete packaging solution for RF module by integrating embedded passives components and MMIC at the package level”.
