The 14 nanometer (14 nm) semiconductor device fabrication node is the technology node following the 22 nm/(20 nm) node. The naming of this technology node as "14 nm" came from the International Technology Roadmap for Semiconductors (ITRS). One nanometer (nm) is one billionth of a meter. The 14nm refers to the "minimum feature size". Until about 2011, the node following 22nm was expected to be 16nm.
The first 14 nm scale devices were shipped to consumers by Intel in 2014.
14 nm resolution is difficult to achieve in a polymeric resist, even with electron beam lithography. In addition, the chemical effects of ionizing radiation also limit reliable resolution to about 30 nm, which is also achievable using current state-of-the-art immersion lithography. Hardmask materials and multiple patterning are required.
A more significant limitation comes from plasma damage to low-k materials. The extent of damage is typically 20 nm thick, but can also go up to about 100 nm. The damage sensitivity is expected to get worse as the low-k materials become more porous.
Tela Innovations and Sequoia Design Systems developed a methodology allowing double exposure for the 16/14 nm node. c.2010.
On February 18, 2011, Intel announced that it would construct a new $5 billion semiconductor fabrication plant in Arizona, designed to manufacture chips using the 14 nm manufacturing processes and leading-edge 300 mm wafers. The new fabrication plant was to be named Fab 42, and construction was meant to start in the middle of 2011. Intel billed the new facility as "the most advanced, high-volume manufacturing facility in the world," and said it would come on line in 2013. Intel has since decided to postpone opening this facility and instead upgrade its existing facilities to support 14-nm chips. On May 17, 2011, Intel announced a roadmap for 2014 that included 14 nm transistors for their Xeon, Core, and Atom product lines.
In 2005, Toshiba demonstrated 15 nm gate length and 10 nm fin width using a sidewall spacer process. It has been suggested that for the 16 nm node, a logic transistor would have a gate length of about 5 nm. In December 2007, Toshiba demonstrated a prototype memory unit that used 15 nanometer thin lines.
In December 2012, Samsung Electronics taped out a 14 nm chip.
In September 2013, Intel demonstrated an Ultrabook laptop that used a 14 nm Broadwell CPU, and Intel CEO Brian Krzanich said, "[CPU] will be shipping by the end of this year." However, shipment was delayed further until Q4 2014.
In August 2014, Intel announced details of the 14 nm microarchitecture for its upcoming Core M processors, the first product to be manufactured on Intel's 14 nm manufacturing process. The first systems based on the Core M processor were to become available in Q4 2014 — according to the press release. "Intel's 14 nanometer technology uses second-generation Tri-gate transistors to deliver industry-leading performance, power, density and cost per transistor," said Mark Bohr, Intel senior fellow, Technology and Manufacturing Group, and director, Process Architecture and Integration.
On March 9, 2015, Apple Inc. released the "Early 2015" MacBook and MacBook Pro, which utilized 14 nm Intel processors. Of note is the i7-5557U, which has Intel Iris Graphics 6100 and two cores running at 3.1 GHz, using only 28 watts.
On September 25, 2015, Apple Inc. released the iPhone 6S and iPhone 6S Plus, which are equipped with "desktop-class" A9 chips that are fabricated in both 14 nm by Samsung and 16 nm by TSMC (Taiwan Semiconductor Manufacturing Company).
In June 2016, AMD released its Radeon RX 400 GPUs based on the Polaris architecture, which incorporates 14 nm FinFET technology from Samsung. The technology was licensed to GlobalFoundries for dual sourcing.
