Intel Foundry Archives Newsroom Powervia marks intel’s transition from traditional front side power delivery to a groundbreaking backside approach, where power rails are routed beneath the silicon substrate, freeing up the front side for signal wiring. Intel foundry is the first to successfully implement both ribbonfet gate all around (gaa) transistors and powervia back side power technology for foundry customers.
Intel Foundry Achieves Major Milestones Intel Newsroom Intel's 18a process is built around the backside power delivery network, or bspdn, a structural overhaul known inside intel as powervia. instead of routing power through the chip's top. Powervia is intel’s proprietary backside power delivery system designed for its 18a process node. traditionally, power delivery to a chip’s transistors occurs via the front side of the chip, where power and ground connections are routed through metal layers on the surface of the chip. Intel's foundry ambitions have shifted from a hopeful turnaround story into a tangible powerhouse narrative. following the momentum of its 18a node, the company's successor technology, the 1.4nm. That innovation is backside power delivery network (bspdn), branded by intel as powervia. powervia fundamentally rethinks how power is delivered inside a chip. traditional processes route both power and signals on the front side of the wafer, creating congestion as transistor density increases.

Intel’s backside power solution is called powervia, and two new papers to be published at the 2023 vlsi symposium show that intel devised a process to manufacture it, test it and demonstrate positive performance results. Intel 18a, the cutting edge process node from intel foundry, is set for production by 2025. featuring ribbonfet and powervia, it will enable foundry clients to achieve higher processor scalability and efficiency, accelerating advancements in ai computing. Industry first powervia backside power delivery technology, improving density and cell utilization by 5 to 10 percent and reducing resistive power delivery droop, resulting in up to 4 percent iso. This is intel’s inaugural process node to integrate ribbonfet gate all around transistors together with powervia backside power delivery, a structural enhancement aimed at closing long standing.
