CoWoS, SoIC, and Foveros: How Advanced Chip Packaging Actually Works

Modern chips are split into many dies, then wired back together in the package. Three technologies do that reintegration: TSMC's CoWoS and SoIC and Intel's Foveros and EMIB. Here is how 2.5D and 3D packaging physically differ, what the CoWoS variants change, and why the packaging line, not the

HBM Explained: Why High-Bandwidth Memory Is the Real Bottleneck in AI Chips

Peak FLOPS are a distraction. The real constraint in every AI accelerator is how fast memory can feed the compute, and HBM is that constraint. Here is how it is built, why inference is memory-bound, why HBM4 doubles the bus instead of the clock, and why packaging, not silicon, is the supply
