HBM (High Bandwidth Memory) and Advanced Packaging Technology for AI Era

The semiconductor packaging industry is expected to grow in the coming years, driven by the increasing demands for semiconductor chips in various applications, such as smartphones, autonomous vehicles, 5/6G, high-performance computing, IoT devices, and artificial intelligence. Another trend is the increasing adoption of heterogeneous integration, where different types of chips, such as CPUs, GPUs, and memory, are integrated into a single package to improve performance and reduce power consumption.

To overcome the limitations of performance/power/density/bandwidth of cutting edge systems, and to create new business opportunity and new values, the importance of advanced packaging technologies is more increased. For the above reasons, the future of the semiconductor packaging industry looks promising, with the increasing demand for semiconductor chips in various applications and the emergence of new packaging technologies driving growth and innovation in the semiconductor industry.

Major semiconductor players accelerate the competition to lead semiconductor industry hegemony by the evolution of advanced packaging technology such as chiplets and 2.5D/3D heterogeneous integration.

SK hynix drive the innovation of packaging technology to meet the demand for higher bandwidth and capacity of memory devices requiring in the increased AI workload applications such as the advent of ChatGPT, an artificial intelligence chatbot. High bandwidth memory (HBM), offers the largest capacity and bandwidth and also comes with the most improved power efficiency enabled by an advanced packaging technology of novel 3D chip stacking. SK Hynix is taking the lead in the HBM market. It developed the world’s first HBM in cooperation with AMD in 2013 and continuously released second/third/fourth-generation HBMs (HBM2/HBM2E/HBM3), and has secured a market share of 60-70 percent. The chip-let technology based on heterogeneous integration will be another key driver for memory-centric systems various combination of logic and memory devices. By the evolution of advanced packaging technologies, SK Hynix will continuously lead the competitiveness of memory business and prepare the business innovation for beyond memory era.
