Intel Unveils Intel 18A-P Process with 18 Percent Power Reduction

Intel has officially announced the Intel 18A-P, an advanced iteration of its 1.8-nanometer class process technology, and has initiated risk production. This new node builds upon the solid foundation of the original Intel 18A, inheriting core structural innovations such as RibbonFET Gate-All-Around transistors, PowerVia backside power delivery, cell heights ranging from 180 to 160 nanometers, and a 50-nanometer Contacted Poly Pitch.

By introducing multiple transistor options, Intel has successfully driven performance gains and reduced power consumption simultaneously. Compared to the standard Intel 18A, the 18A-P variant delivers a 9 percent increase in performance and an 18 percent reduction in power consumption. Technical improvements include a reduction in thermal resistance by 20 to 40 percent and an improvement in via resistance by 10 to 30 percent. Furthermore, the efficiency of the transistors has been enhanced through strain engineering to improve P-channel Metal-Oxide-Semiconductor mobility. This optimization comes at a critical time as global data centers and artificial intelligence accelerators demand unprecedented energy efficiency alongside high-density computing capabilities.
