JEDEC has reportedly provided relaxation for HBM4 memory participants, potentially allowing a more efficient development for 16-Hi designs.
JEDEC Eases HBM4 Thickness Thresholds For Manufacturers Including Samsung, SK Hynix & Micron, Removing The Need For Hybrid Bonding Tech For 16-Hi Stacks
HBM4 is the next big thing in the memory segment, with every firm involved in developing the memory type most effectively since it would ultimately set the course for success in the next-gen markets.
To aid manufacturers, ZDNet Korea reports that JEDEC has decided to reduce the package thickness of HBM4 to 775 micrometers for both 12-layer and 16-layer HBM4 stacks, amid the complexities involved with a higher thickness level, along with the highly anticipated demand associated with the process.
Moreover, manufacturers were previously said to employ hybrid bonding with the process, a newer packaging technology, to reduce package thickness since it uses direct bonding with the onboard chip and wafer.
However, since HBM4 memory will be a new technology, it is expected that employing hybrid bonding will result in an overall bump in pricing, which means that next-gen products will be much more pricey, but the use of hybrid bonding isn't certain yet, as HBM manufacturers would probably leverage the "relaxation" made by JEDEC.
Regarding when we could see the debut of HBM4-based products, SK hynix has plans to mass-produce it by 2026, with initial samples expected to feature up to 36 GB capacities per stack. HBM4 is known to revolutionize the AI markets regarding computing performance since the memory type will employ "revolutionary" onboard die configurations by combining logic and semiconductors into a single package. Because TSMC and SK hynix have recently created an alliance, HBM and semiconductor markets are expected to proceed in a collaborative environment.
