ABSTRACT
Because of the drive of Moore’s law, SoC (system-on-chip) has been very popular in the past 10+ years. Unfortunately, the end of Moore’s law is fast approaching and it is more and more difficult and costly to reduce the feature size (to do the scaling) to make the SoC. Heterogeneous integration contrasts with SoC. Heterogeneous integration uses packaging technology to integrate dissimilar chips with different functions into a system or subsystem. For the next few years, we will see more implementations of a higher level of heterogeneous integration, whether it is for time-to-market, performance, form factor, power consumption or cost. Fan-out wafer-level packaging (FOWLP) has been getting lots of tractions since TSMC used their FOWLP to package the application processor for the iPhone 7. In this lecture, the following topics will be presented and discussed. Emphasis is placed on the latest developments of these areas in the past three years. Their future trends will also be explored.
