Abstract
The heterogeneous integration of chiplets addresses many of the technical and logistical challenges associated with SoCs to meet the ever-increasing demands from a variety of emerging markets including IoT and mm-wave 5G. These integrated systems are conventionally permanently integrated/interconnected in a fixed configuration via either microbumps or other advanced off-chip interconnect technologies. However, some applications require the heterogeneity and fine-pitch provided by these multi-chiplet polylithic systems while also requiring a non-permanent or replaceable setup to meet a variety of needs or to enable a variety of applications: reworkability, testing, prototyping, upgradeability, etc. Furthermore, as systems continue to integrate a growing number of chiplets, package/system yield can suffer considerably when in a permanent configuration; a replaceable setup can directly address this problem. To address the aforementioned challenges, this research presents novel, replaceable heterogeneously integrated systems using socketed platforms for different targeted applications. In general, such a system requires two enabling technologies: 1) a non-permanent off-chip interconnection system and 2) a non-permanent alignment technology. Hence, this research also introduces the design, fabrication, and characterization of off-chip flexible interconnects and mechanically-based self-alignment technologies.
