Beyond 10 nm at TSMC: 7 nm DUV and 7 nm EUV. What's the point of 50nm EUV if DUV can already achieve this as illustrated in my answer. ASML's deep ultraviolet (DUV) lithography systems dive deep into the UV spectrum to print the tiny features that form the basis of the microchip. This new technology, which enables a breakthrough in production of next-generation chips, is the sole property of ASML. Returns as of 07/31/2020.If EUV continues to take off not only for leading-edge chips, but also some types of memory production -- currently in a test phase -- ASML's run could just be getting started.ASML makes many of the types of machines used in the memory and semiconductor manufacturing process. Double or multiple patterning would also be required if a pattern consists of sub-patterns which require significantly different optimized illuminations, due to different pitches, orientations, shapes, and sizes.For pitches of 40 nm or below, the linewidths are 20 nm or less, while the CD difference is at least 2.5 nm, resulting in at least 12.5% difference.Even with higher absorption, EUV has a larger shot noise concern than the ArF (193 nm) wavelength, mainly because it is applied to smaller dimensions and current dose targets are lower due to currently available source power levels.+ A process variation tolerance area is the largest region over which process variation is allowed.Source: Gigaphoton, Sematech Symposium Japan, September 15, 2010In other words, the less absorbing the resist, the more vertically uniform the absorption.
Producers have gotten around this by running chips through many, many rounds of lithography tools, doing a tiny bit at a time.Stock Advisor launched in February of 2002.
Growth will be centered on the foundry and logic segments, and especially EUV machines, which enable production of today's leading-node chips.It also provides services for the installed base of machines.In fact, results were so strong that ASML hiked its annual dividend by 50% in 2018, to 2.10 euros per share, up from 1.40 euros per share.

Immersion systems are the workhorses of the industry. As noted previously, TSMC’s 7 nm node will be used by tens of companies for hundreds of chips targeting different applications. Thanks to these packages, any NXT system can be upgraded to the latest technology. Even more exciting? You have requested a machine translation of selected content from our databases. For one thing, the technology is extremely difficult to get right. EUV has been under development for over 20 years and has been hugely expensive, and there was no certainty it would ever work. This also means shot noise is worse toward the bottom of a highly absorbing EUV resist layer.The resolution of EUV lithography for the future faces challenges in maintaining throughput, i.e., how many wafers are processed by an EUV tool per day. We continue to innovate our immersion systems to meet the requirements of future nodes, benefiting from commonalities in R&D with our EUV program, while ensuring the platform’s extendibility through System Node Enhancement Package upgrades.
Shot noise is another concern, to be explained further below.As mentioned earlier, a more absorbing resist actually leads to less vertical dose uniformity. Extreme ultraviolet lithography (also known as EUV or EUVL) is a lithography technology using a range of extreme ultraviolet (EUV) wavelengths, roughly spanning a 2% FWHM bandwidth about 13.5 nm.
Well, it depends. Extreme ultraviolet radiation (EUV or XUV) or high-energy ultraviolet radiation is electromagnetic radiation in the part of the electromagnetic spectrum spanning wavelengths from 124 nm down to 10 nm, and therefore (by the Planck–Einstein equation) having photons with energies from 10 eV up to 124 eV (corresponding to 124 nm to 10 nm respectively). As noted previously, TSMC’s 7 nm node will be used by tens of companies for hundreds of chips targeting different applications. EUV use is only just starting to be used in commercial mass production.Roughly 70% of ASML sales came from its various DUV machine offerings.
This EUV production can thus cut out many DUV lithography steps, potentially reducing DUV steps in certain parts of the process by 67% to 75%.How much savings does this yield for semiconductor manufacturers?
After selling 11 EUV tools in 2017 for early production, and 18 machines in 2018, management expects to sell 30 EUV tools in 2019, powering its overall growth.While most equipment makers are forecasting declines in 2019, ASML management is forecasting "another sales growth year in 2019."
