Backside Power Delivery
A chip architecture moving power routing to the underside of the wafer, freeing the front for signal wiring; a key node-transition technology.
Backside Power Delivery is an emerging chip architecture that moves power-delivery wiring to the underside of the wafer, freeing the front side for denser signal routing. It improves performance and power efficiency at advanced nodes and is a defining feature of Intel's 18A and TSMC's upcoming nodes. The technique is one of the structural enablers of sub-2nm manufacturing. See Foundry Economics 101.
