10 nm lithography process

The 10 nanometer (10 nm) lithography process is a semiconductor manufacturing process node serving as shrink from the 14 nm process. The term "10 nm" is simply a commercial name for a generation of a certain size and its technology, as opposed to gate length or half pitch. The 10 nm node is currently being introduced and is set to get replaced by the 7 nm process in 2018/2019.


First introduced between 2017-2019, the 10 nm process technology is characterized by its use of FinFET transistors with a 30-40s nm fin pitches. Those nodes typically have a gate pitch in range of 50-60s nm and a minimum metal pitch in the range of 30-40s nm. Due to the small feature sizes, for the critical dimensions, quad and triple patterning were introduced for the first time in high-volume manufacturing.


At the advanced 10nm process, there are only 3 semiconductor foundries with such manufacturing capabilities: Intel, Samsung, and TSMC.

Due to marketing names, geometries vary greatly between leading manufacturers. Although both TSMC and Samsung's 10nm processes are slightly denser than Intel's 14nm in raw logic density, they are far closer to Intel's 14nm than they are to Intel's 10nm (e.g., Samsung's metal pitch just 1 nanometer shorter than Intel's 14nm).

Announced during Intel's Technology and Manufacturing Day 2017, Intel's 10 nm process (P1274) is Intel's first high-volume manufacturing process to employ Self-Aligned Quad Patterning (SAQP) with production starting in the second half of 2017. Intel detailed Hyper-Scaling, a marketing term for a suite of techniques used to scale a transistor, SAQP, a single dummy gate and contact over active gate (COAG). Intel's initial 10 nm process has up to 60% lower power and 25% better performance than their initial 14 nm but will actually have lower performance than their "14nm++" process. Intel expect their "10nm+" process to surpass that.

Intel's 10nm process is roughly 1.7x the raw logic density of the next densest 10nm process, albeit due to aggressive pattering techniques they also have the most complex process available to date. The process can support multiple threshold voltages, and features 12-metal interconnect layers with the bottom two made of cobalt. This is the first time cobalt is used in a high volume production node. Because of the ever shrinking geometries the wires get smaller each node.

At 10nm the wires become so small that the barrier layer takes up most of the interconnect, resulting in less space for the copper itself. As the cross section of the wire gets smaller the resistance rises exponentially. Cobalt aims to address this issue, it does not diffuse in the surrounding material, so the barrier layer can be reduced. And even though it has a higher resistance than copper in bulk, it has up to two times lower resistance in very small wires. This can be attributed to the larger wires because of the reduced barrier layer and the larger grain size, which reduces the electron scattering. It also has 10x better resistance to electron-migration.

Intel will leverage their initial 10nm process for their Cannon Lake-based microprocessors which are used exclusively for mobile. They will then utilize their second generation, "10nm+" process, for Ice Lake-based processors which will be used for the mainstream and server platform.

Intel 7 Ultra[edit]
New V-F Curve for the Enhanced Intel 7 process.

Intel introduced an enhanced version of the Intel 7 process in late 2022 with the introduction of the company's 13th Generation Core processors based on the Raptor Lake microarchitecture. Nicknamed "Intel 7 Ultra" internally, the new process is a full PDK update over the one used by Alder Lake, their 3rd generation SuperFin Transistor architecture. Intel says this process brings transistors with significantly better channel mobility. At the very high end of the V-F curve, the company says peak frequency is nearly 1 GHz higher now. The curve itself has been improved, shifting prior-generation frequencies by around 200 MHz at ISO-voltage, or alternatively, reducing the voltage by over 50 mV at ISO-frequency.

Samsung demonstrated their 128 Megabit SRAM wafer from their 10nm FinFET process. Samsung, which unlike Intel uses LELELE (litho-etch-litho-etch-litho-etch), ramped up mass production in May of 2017. ChipWorks/TechInsight measured the CPP/MMP which came a little short of the Common Platform Alliance Paper which was presented in 2016, at 68 nm contacted gate pitch, 51 nm metal pitch, dual-depth shallow trench isolation (STI), and had single dummy gate.

Samsung's initial process was 10LPE (10 Low-Power Early) which was replaced by second generation evolved process 10LPP (10 Low-Power Plus). Samsung intends to introduce a third generational enhanced 10nm process called 8LPP (8 Low Power Plus) which will further improve performance and introduce a small density increase through cell enhancements and a narrower metal pitch. 8LPP improvements over 10LPP is similar to their 11LPP improvements over their 14LPP. It's worth noting that Samsung intends 8LPP to be their last non-EUV node. All subsequent nodes will use EUV.


TSMC reported a poly pitch of 64 nm with a metal pitch 42 nm. TechInsight measured them at 66 nm and 44 nm respectively. 10FF is the second process to use FinFET, and is the Industry's first use of Quad-Patterning. This allows for a full node shrink, enabling a 2X increase in logic density compared to their 16nm process. The 10FF process will have 15% higher performance while consuming 35% less power.
