The '''5 nanometer (5 nm or 50 Å) lithography process''' is a [[technology node]] semiconductor manufacturing process following the [[7 nm lithography process|7 nm process]] node. Commercial [[integrated circuit]] manufacturing using 7 nm process is set to begin sometimes around 2020.
  
 
The term "5 nm" is simply a commercial name for a generation of a certain size and its technology, and '''does not''' represent any geometry of the transistor.

== Overview ==

== Industry ==
−
First introduced by the major foundries around the [[2020]] timeframe, the 5-nanometer [[process technology]] is characterized by its use of [[FinFET]] transistors with fin pitches in the 20s of nanometer and densest metal pitches in the 30s of nanometers. Due to the small feature sizes, these processes make extensive use of EUV for the critical dimensions, along with quad patterning for the fins and double patterning for the rest of the metal stack. Note that Intel [[7 nm process]] is comparable to the foundry 5-nanometer node.

=== Density ===
 
−
In terms of raw cell-level density, the 5-nanometer node features silicon densities between 130-230 million [[transistors per square millimeter]] based on WikiChip's own analysis.

In May of 2017, Intel's Technology and Manufacturing Group Director, Mark Bohr, confirmed that Intel was already started researching their 5 nm node as their 7nm was already in development phase.
−
Intel 4 process, codenamed '''P1276''', formerly Intel 7-nanometer process, will enter risk production at the end of 2022 and ramp in 2023. On February 8 2017, Intel announced a $7B investment in Arizona's Fab 42 which will eventually produce chips on a 7 nm process. On March 23 2021, Intel announced a $20B investment for two fabs in Arizona, which will produce chips on a 7nm process.

=== TSMC ===
 
−
TSMC started mass production of its '''5-nanometer N5 node''' in April 2020. TSMC considers its 5-nanometer node a full node shrink over its [[N7|7-nanometer process]]. In early 2021 TSMC plans on introducing a second version of its N5 process called '''N5P''' which provides additional performance enhancements.
 
−
 
 
−
==== N5 ====
 
−
TSMC started its [[risk production]] of the 5-nanometer, '''N5''', node in March 2019. The process ramped in April 2020. The N5 process is a [[full node]] successor to the company's [[N7 node]], featuring 1.84x improvement in logic density.
 
−
 
 
−
The N5 node continues to use [[bulk silicon]] [[FinFET transistors]]. Leveraging their experience from 7+, 5 nm makes extensive use of [[EUV]] for more critical layers in order to reduce the [[multi-patterning]] complexity. It is believed that TSMC N5 process uses 11-13 EUV masks in order to replace about 35 immersion layers that would otherwise be required to produce the same pattern without EUV. In other words for TSMC to go from its [[N7]] node to its [[N5]] node would entail going from roughly 87 [[masks]] to 115 masks. The introduction of EUV reduced this number back down to around 81 masks.

[[File:n5-ppa.png|200px|thumb|right|N5 PPA]]
 
−
At a high level, TSMC N5 is a high-density high-performance [[FinFET]] process designed for mobile SoCs and HPC applications. Fabrication makes extensive use of EUV at Fab 18, the company’s new 12-inch GigaFab located at the Southern Taiwan Science Park. TSMC says that its 5-nanometer process is 1.84x denser than its [[N7|7-nanometer node]]. TSMC also optimized analog devices where roughly 1.2x scaling has been achieved. TSMC reported the density for a typical mobile SoC which consists of 60% logic, 30% SRAM, and 10% analog/IO, their 5 nm technology scaling was projected to reduce chip size by 35%-40%.

−
In order to improve the drive current, TSMC introduced a [[high-mobility channel]] (HMC) for its 5-nanometer [[FinFET devices]]. We believe TSMC is employing a SiGe channel for the pMOS devices. It has been suggested that the channel has 37% Ge composition. TSMC says that the HMC delivers 18% performance gain versus equivalent Si finFETs.

[[File:N5 mx rc and vx rc.png|right|thumb|200px|Tightest pitch Mx RC and Vx RC on 5nm was kept at similar levels to N7.]]
 
−
Despite aggressively tighter pitches, TSMC says metal lines RC and via resistance have been kept relatively similar to N7. TSMC says this was achieved by "using EUV patterning, innovative scaled barrier/liner, ESL/ELK dielectrics, and Cu reflow." The improvements meant the interconnect RC did not worsen relative to N7 as N7 did relative to N16.
 
−
 
 
−
The 5 nm node is expected to deliver a 15% improvement in performance at [[iso-power|constant power]] or a 20% reduction in power at [[iso-performance|constant performance]]. In addition to the ultra-LVT (uLVT) that was offered with [[N7]], there is a new extreme-LVT (eLVT) which can push that 15% up to 25% higher speed at Vdd. Additionally, compared to the standard N5 cells, the HP cell variants can push that performance by another 10% at the cost of density.
 
−
 
 
−
The N5 node makes use of a number of [[density boosters]] under a marketing term called "smart hyper-scaling features" (similar to Intel). N5 introduces [[single diffusion breaks]] in order to reduce cell spacing. Additionally, TSMC added the ability to drop the gate contact over the active region (COAG). Although originally experimented with at the N7 node, [[via pillars]] are also used extensively in the N5 node. TSMC makes extensive use of [[via pillars]] in N5 due to the three-fold increase of Mx resistance.

===== SRAM =====
 
−
Two [[6T]] [[SRAM]] [[bitcells]] were disclosed by TSMC. The high-performance cell is 0.025 µm² while the high-density cell is 0.021 µm². Assuming a ballpark assist circuit overhead of around 30%, the high-density cells yields an estimate of ~32 Mib/mm² of cache. This an increase of 30% from [[N7]] which is around 24.7 Mib/mm². At ISSCC 2020, TSMC presented a test shuttle with 135 Mib of HD SRAM and additional IPs. Their reported density for the HD cells is similar to our estimates.

==== N5P ====
 
−
As with their 7-nanometer process, TSMC will offer an optimized version of their N5 process called '''N5 Performance-enhanced version''' ('''N5P'''). This process uses the same design rules and is fully IP-compatible with N5. Through FEOL and MOL optimizations, N5P will offer 7% higher performance over N5 at [[iso-power]] or 15% lower power at [[iso-performance]]. Risk production for N5P is expected to start around the fourth quarter of 2020 with volume production starting sometimes in 2021.

==== 5LPE ====

Samsung '''5-Nanometer Low-Power Early''' ('''5LPE''') design development completed in early 2019. Unlike TSMC's 5-nanometer node, 5LPE is considered to be only a [[quarter node]] successor to the company's [[7-nanometer 7LPP]] process, delivering 1.3x density improvement through a new [[standard cell library]] as well as new [[scaling boosters]]. Samsung 5LPE process provides different benefits depending on the migration path selected from 7LPP. Moving to a similar [[7.5T library]] will provide 11% performance improvement through various transistor optimizations ([[Low-k spacer]], DC enhancement, etc.). Alternatively, moving to the new [[6T library]] provides around 33% higher density.

Samsung 5LPE provides two main libraries - [[7.5T library]] (HD) for performance and a [[6T library]] (UHD) for the area and power optimizations. The 7.5T library utilizes a relaxed 60 nm [[poly pitch]] with 10 diffusion lines for a [[cell height]] of 270 nanometers. This is identical to the [[7LPP]] library. In the 7LPP process, Samsung also offered a high-density 6.75T cell library with a tighter 54 nm CPP that had 9 diffusion lines. In 5LPP, the new 6T library also utilizes the 54 nm CPP but reduces the diffusion lines to 8 for an even shorter cell height of 216 nm.

=== Common Platform Alliance Paper ===
 +
In a joint paper by the [[Common Platform]] (IBM, GlobalFoundries, Samsung) a 5nm node was proposed at the 2017 VLSI Symposium. The paper presents a new horizontally stacked sheet [[gate-all-around]] (GAA) FET with good properties which can be a good candidate for the replacement of FinFET at the 5nm node. The paper reports transistors with an aggressive L<sub>g</sub> of 12 nm and a contacted poly pitch of 48 nm.

[[File:ibm stacked silicon nanowire transistors.jpg|400px]]

The '''4-nanometer Low-Power Early''' ('''4LPE''') process is a continuation of Samsung's 7LPP and 5LPE, inheriting the transistor and most of the ground rules from 7LPP. This is Samsung's last [[FinFET]]-based process. 4LPE features similar pitches to 5LPE but introduces slightly tighter metal pitches.
