Competition in the semiconductor industry is becoming fiercer and advanced package technology has become important for achieving low-power and high performance computing. As the Moore’s law reach the limitation, Si fabrication process need extremely high cost solutions such as multiple patterning and EUV (Extreme Ultra-Violet) lithography. In spite of high cost Si fabrication process, chip size is increased over the reticle size limit by adding more and more functional blocks for high performance computing. In particular, with the continuous demand for higher performance and capacity in memory products, the amount of data created, processed, stored and transferred is increasing tremendously. In order to overcome these challenges, advanced package based on RDL (Re-Distribution Layer), flip chip bonding, and TSV (Through Silicon Via) have been actively used for heterogeneous integration in electronic packages since the past decade. The heterogeneous integration and chiplet has been attracting a lot of attention since it enables higher bandwidth with low power consumption at reduced cost. 2.5D Si interposer architecture has been widely used for horizontal interconnection between logic to logic and logic to high bandwidth memory integration. 3D stacking architecture is for vertical interconnections enabling small form factor, increasing signal speed, reducing power consumption and power dissipation. In this talk, recent advanced package technology and key roadmap in Samsung Electronics will be shared for mobile and AI/HPC product.

Co-Packaged Optics is the combination of photonic integrated circuits and electronic circuits at a system packaging level. The essential need is to get light in and out of the system, usually from optical fibers, with the least losses and ease of manufacturing. Photonic integrated circuits (PICs) are fabricated in CMOS semiconductor fabrication facilities, which allows manufacturers to take advantage of the large installed base of tools and processes. However, electronic packaging is currently not equipped to handle the challenges associated with packaging advanced photonic devices. In this presentation we explore some of these challenges for optical coupling such as sub-micron alignment tolerances, sensitivity to temperature variations, optical losses, and a lack of standards. The end objective is to have optical coupling look like electronic coupling. At NYCREATES/AIM Photonics, we have learned that the best results are obtained when the PIC manufacturing and packaging processes are co-designed to better achieve low-loss coupling, particularly between photonic integrated circuits and other elements in the system. A complete “end-to-end” approach includes customizing the PIC process, wafer manufacturing including interposers and heterogeneous integration, electronic photonic design automation, and electronic-photonic test, assembly and packaging capabilities. A complete approach will lead to reliable and affordable solutions that will ensure the manufacturing-readiness of this critical technology for decades to come.

Rapid growth of generative AI at this moment has never been experienced for a few decades and it makes surprising impact to human experience and semiconductor industry as well. High bandwidth memory (HBM) which started from memory solution for high-end graphic applications has being emerged as a key driver accelerating the growth of AI industry due to remarkable advantages on the smaller latency between memory and GPU.

SK hynix has been the pioneer of HBM in all of history and firstly wrote a new record by the world-first development of HBM package in 2013. More remarkable footprint in the HBM history was the world-first adoption of the mass reflow bonding and molded underfill (MR-MUF) technology to the HBM 4Hi and 8Hi in 201, which nobody has never tried due to its notorious difficulties of process and material technologies. In this effort, SK hynix is providing a state-of-the-art of HBM products with highest memory bandwidth and memory capacity, highest power efficiency, and superior thermal dissipation ability and its package technology is a core competency leading the memory renaissance in the post-pandemic era.

In align with HBM technology innovation, there are continuous changes in 2.5D system-in-package (SiP) in order to improve the memory bandwidth and accommodate higher memory capacity. There has been many different types of proxy package structure to assure the HBM quality and reliability but it is obviously not certain whether HBM package can guarantee all the possible quality and reliability risks due to many possible changes of HBM and SiP packages in the future. In this paper, we would like to introduce several ways to evaluate the thermal and electrical characteristics of HBM and its package reliability.

Materials innovation within the Semiconductor industry has been a driving force since the planar 2D MOSFET to the current 3D gate-all-around (GAA) transistor architectures and will continue its criticality as we embark on 500-layer flash memory designs and Angstrom level critical interconnect dimensions. To achieve these once incomprehensible levels of lateral and vertical scaling, device design engineers and manufacturers are increasingly relying on disruptive materials innovation to enable the density and performance gains required at each successive technology node. As the performance requirements for the most advanced devices become more challenging, materials have shown to have an increased contribution to device performance over scaling and design. This has led to a greater portion of the periodic table being incorporated into semiconductor processing.

The integration of new materials, such as novel photoresists, interconnect metals & alloys, ultra-pure polymers, chemically modified polymer membranes, and formulated chemicals, into the chip fabrication increases process complexity and makes yield ramps more challenging. With more process steps in the overall device build, speed to yield and process integrity are more critical than ever to achieve technology qualification schedules. This presentation will focus on Entegris’ approach to materials innovation, the integration of these novel materials coupled with co-optimized solutions enabling industry technology roadmaps and yield requirements while preserving integrity of delivery and process control.
