Building the Blackwell NVL72: Millions of Parts, One AI Superchip

[Music] Blackwell is an engineering marvel. It begins as a blank silicon wafer. [Music] Hundreds of chip processing and ultraviolet lithography steps build up each of the 200 billion transistors layer by layer on a 12in wafer.The wafer is scribed into individual blackwell dye, tested and sorted, separating the good dyes to move forward. The chip on wafer on substrate process attaches 32 Blackwell dyes and 128 HPM stacks on a custom silicon interposer wafer. Metal interconnect traces are etched directly into ...
