14 nm process

From Wikipedia, the free encyclopedia
(Redirected from 14 nm)

The "14 nanometer process" refers to a marketing term for the MOSFET technology node that is the successor to the "22 nm" (or "20 nm") node. The "14 nm" was so named by the International Technology Roadmap for Semiconductors (ITRS). Until about 2011, the node following "22 nm" was expected to be "16 nm". All "14 nm" nodes use FinFET (fin field-effect transistor) technology, a type of multi-gate MOSFET technology that is a non-planar evolution of planar silicon CMOS technology.

Since at least 1997, "process nodes" have been named purely on a marketing basis, and have no relation to the dimensions on the integrated circuit;[1] neither gate length, metal pitch or gate pitch on a "14nm" device is fourteen nanometers.[2][3][4] For example, TSMC and Samsung's "10 nm" processes are somewhere between Intel's "14 nm" and "10 nm" processes in transistor density, and TSMC's "7 nm" processes are dimensionally similar to Intel's "10 nm" process.[5]

Samsung Electronics taped out a "14 nm" chip in 2014, before manufacturing "10 nm class" NAND flash chips in 2013.[dubiousdiscuss][clarification needed] The same year, SK Hynix began mass-production of "16 nm" NAND flash, and TSMC began "16 nm" FinFET production. The following year, Intel began shipping "14 nm" scale devices to consumers.[needs update]

History

[edit]

Background

[edit]

The resolutions of a "14 nm" device are 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,[6] but can also go up to about 100 nm.[7] The damage sensitivity is expected to get worse as the low-k materials become more porous. For comparison, the atomic radius of an unconstrained silicon is 0.11 nm. Thus about 90 Si atoms would span the channel length, leading to substantial leakage.

Tela Innovations and Sequoia Design Systems developed a methodology allowing double exposure for the "16 nm"/"14 nm" node circa 2010.[8] Samsung and Synopsys had also, at that time, begun implementing double patterning in "22 nm" and "16 nm" design flows.[9] Mentor Graphics reported taping out "16 nm" test chips in 2010.[10][needs update] On January 17, 2011, IBM announced that they were teaming up with ARM to develop "14 nm" chip processing technology.[11][needs update]

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.[12][13] 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 since decided to postpone opening this facility and instead upgrade its existing facilities to support 14-nm chips.[14][needs update] On May 17, 2011, Intel announced a roadmap for 2014 that included "14 nm" transistors for their Xeon, Core, and Atom product lines.[15][needs update]

Technology demos

[edit]

In the late 1990s, Hisamoto's Japanese team from Hitachi Central Research Laboratory began collaborating with an international team of researchers on further developing FinFET technology, including TSMC's Chenming Hu and various UC Berkeley researchers. In 1998, the team successfully fabricated devices down to a 17 nm process. They later developed a 15 nm FinFET process in 2001.[16] In 2002, an international team of researchers at UC Berkeley, including Shibly Ahmed (Bangladeshi), Scott Bell, Cyrus Tabery (Iranian), Jeffrey Bokor, David Kyser, Chenming Hu (Taiwan Semiconductor Manufacturing Company), and Tsu-Jae King Liu, demonstrated FinFET devices down to 10 nm gate length.[16][17]

In 2005, Toshiba demonstrated a 15 nm FinFET process, with a 15 nm gate length and 10 nm fin width, using a sidewall spacer process.[18] It had erstwhile been suggested in 2003 that for the 16 nm node, a logic transistor would have a gate length of about 5 nm.[19][needs update] In December 2007, Toshiba demonstrated a prototype memory unit that used 15-nanometre thin lines.[20]

In December 2009, National Nano Device Laboratories, owned by the Taiwanese government, produced a "16 nm" SRAM chip.[21][needs update]

In September 2011, Hynix announced the development of "15 nm" NAND cells.[22][needs update]

In December 2012, Samsung Electronics taped out a "14 nm" chip.[23][needs update]

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."[24] However, as of February 2014, shipment had at time erstwhile been delayed further until Q4 2014.[25][needs update]

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.[26][needs update]

In 2018 a shortage of "14 nm" fab capacity was announced by Intel.[27][needs update]
