Intel's Latest Innovations in Semiconductor Manufacturing

Intel recently showcased some exciting advancements in semiconductor manufacturing at the International Solid-State Circuits Conference (ISSCC). The company introduced its highly anticipated Intel 18A process technology, demonstrating significant improvements in SRAM bit cell density.

At the core of Intel's node are the PowerVia system and RibbonFET (GAA) transistors. The company has made solid progress in high-performance SRAM cells, reducing the size from 0.03 µm² in Intel 3 to 0.023 µm² in Intel 18A. High-density cells have also seen improvement, shrinking to 0.021 µm². These advancements represent scaling factors of 0.77 and 0.88, marking significant achievements in SRAM technology.

Intel's implementation of PowerVia technology is a first-of-its-kind approach to addressing voltage drops and interference in processor logic areas. By strategically applying PowerVias to I/O, control, and decoder elements using an "around the array" scheme, Intel has optimized bit cell design without a frontal power supply. The macro bit density of 38.1 MBit/mm² achieved by Intel 18A positions the company competitively in the market.

While TSMC has reported similar figures with their N2 process, Intel's comprehensive approach with 18A, combining PowerVia and GAA transistors, could potentially challenge industry leaders like Samsung and TSMC. Intel aims to compete for premium clients currently served by TSMC, including tech giants such as NVIDIA, Apple, and AMD.
