Abstract
In the world of high performance computing, over a decade the performances of the computing has constantly increase beyond the almost automatic but slowing down improvement in processor performance with Moore's Law. Big players have moved to new architectures such as chiplets only possible thanks to the integration of More-than-Moore technologies. 2.5D and 3D integration, memory cubes, accelerators and heterogeneous architectures are key elements of the success towards performance and energy efficiency. This transition has shown clear benefits and sustainability for HPC market. The question is still open for Edge AI components where real time, ultra-low power, large amount of data, low cost are the main drivers: how can 3D integration play a role for these embedded processors? CEA-Leti has been involved for more than two decades in 3D integration with industrial partners. This presentation will discuss about:- What are the main drivers for computing in edge devices ?- What could be the architectures’ new paradigm ?- How 3D integration will be an enabler, and how CEA-Leti’s roadmap supports this promising technology

MicroLED Advance Bonding Method to enable AR Metaverse

Abstract
Mark Zuckerberg and companies seem to think that smart glasses will one day replace smartphones. They’re not alone, and it will probably happen at some point in the not-too-distant future. But for such a product to exist, we still face plenty of challenges both in hardware and software, especially in the microdisplay that is required for smart glasses. MicroLED is one of the best microdisplay solutions for smart glasses. The key challenges are how to integrate LED arrays from a small epi wafer to a full-size CMOS backplane wafer in a way that is cost-effective. A crude method is coring: the larger CMOS wafer is cored to the size of the epi wafer and the two are bonded with wafer-to-wafer (W2W) bonding tools. This is suitable for R&D and low volume production, but there is too much wasted CMOS wafer to be valid for mass production. Another method is Direct Die-to-Wafer (D2W) Integration: the pixelated frontplane epi wafer is diced and the resulting dies are then bonded to corresponding locations on the backplane wafer. While this reduces the amount wasted, bonding accuracy becomes more challenging, and throughput is potentially slower. GF believes that innovative D2W integration is a good way to increase throughput. In this method, epi dies are first transferred to blank wafer of the same size as the backplane wafer. Standard W2W bonding is then used to finish the integration of frontplane and backplane. In this paper, we will present GlobalFoundries® (GF®) advanced D2W bonding solution to resolve the microLED manufacturing challenges.
