Cu-Cu Hybrid Bonding and Co-Packaged Optics

[]Cu-Cu Hybrid Bonding and Co-Packaged Optics John H Lau Unimicron Technology Corporation John_Lau@Unimicron.com Cu-Cu hybrid bonding is one of the flip chip assembly technologies. The advantages of hybrid bonding are: (a) higher density, (b) finer pad pitch, and (c) better performance. In this lecture, some fundamentals and more than 10 high-volume manufacturing products using hybrid bonding will be presented. On the other hand, co-packaged optics (CPO) are heterogeneous integration packaging methods to integrate the chiplets such as the optical engine (OE) which consists of photonic ICs (PIC) and the electrical engine (EE) which consists of the electronic ICs (EIC) as well as the switch ASIC (application specific IC). The advantages of CPO are: (a) to reduce the length of the electrical interface between the OE/EE (or PIC/EIC) and the ASIC, (b) to reduce the energy required to drive the signal, and (c) to cut the latency which leads to better electrical performance. In the next few years, we will see more implementations of Cu-Cu hybrid bonding and a higher level of heterogeneous integration of PIC and EIC, whether it is for performance, form factor, power consumption or cost. The content of this lecture is shown below.
