Talk: Heterogeneous Integration and HBM (High Bandwidth Memory) in the AI Era

Abstract

As semiconductor technology advances, the difficulty of scaling down increases, and circuits that need to implement a variety of functions are becoming larger. In the AI era, customer demands are diversifying, leading to the need for new technologies in semiconductor development and mass production. One such promising solution is Heterogeneous Integration, a rapidly evolving field with diverse technologies being developed and applied. SK hynix was the first in the world to develop and mass-produce High Bandwidth Memory (HBM) using this technology, and it currently leads the HBM market. Especially starting with HBM4, the market landscape is shifting significantly, and future progress will require collaboration with even more players. Through such partnerships, a new era of AI will be ushered in. This talk will cover an introduction and examples of Heterogeneous Integration, as well as how SK hynix is expanding its HBM technology using it.
