Why only a few foundries make the leading-edge chips

Leading-edge chip manufacturing has collapsed to a handful of companies, in practice one clear leader and two challengers. The reasons are structural: staggering cost, an unforgiving learning curve, and a feedback loop that punishes falling behind. Here is how it works.

What a Nanometer Process Node Really Means

The number on a process node, 7nm, 3nm, now 2nm, is a marketing label, not a measurement of anything physical on the chip. Here is what it actually tracks, and the metrics that describe a chip honestly.

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

TSMC's Pricing Power: How One Foundry Sets the Cost of Every Advanced Chip

TSMC sells wafers, not chips, and prices them by process node. Here is how one foundry's leading-edge grip puts a floor under the cost of every advanced phone chip, GPU, and AI accelerator, why switching is nearly impossible, and where the toll actually lands.

How EUV Lithography Works, in Plain Terms

EUV uses 13.5nm light to print the smallest features on modern chips. The way that light is made, lost, and steered off precision mirrors is one of the strangest feats in manufacturing, and by 2026 it is what makes 2nm-class chips possible.
