Eighteen wafers stack as one chip. Thousands of signal, power and thermal vias thread top-to-bottom through the whole stack. The chip is not laid flat; it is threaded through.

One layer. A single thin silicon wafer, routed on its own. This is one slice of what an AutoPhi chip is made of.

Eighteen layers. More wafers descend one at a time and settle perfectly flush on the one below. By the end there are eighteen in the stack, aligned pad to pad.

Vertical threading ignites. Thousands of hair-thin columns of light flow top-to-bottom through every layer at the same time. Signal in cool white. Power in bright blue. Thermal in muted cyan. The chip is not laid flat; it is threaded through.

Threaded through, not laid flat.
