Provided by Pohang University of Science and Technology A domestic research team has developed a technology to stably stack ultra-thin semiconductor chips, which are about one-fifth the thickness of a human hair, over 10 layers. It is a technology that realizes an integration density approximately four times higher than that of high-bandwidth memory (HBM), which is attracting worldwide attention. Pohang University of Science and Technology (POSTECH) is led by Kim Seok...
