Extreme ultraviolet lithography (EUVL, also known simply as EUV) is a technology used in the semiconductor industry for manufacturing integrated circuits (ICs). It is a type of photolithography that uses 13.5 nm extreme ultraviolet (EUV) light from a laser-pulsed tin (Sn) plasma to create intricate patterns on semiconductor substrates.

In April 2019, TSMC announced that their "5 nm" process (CLN5FF, N5) had begun risk production, and that full chip design specifications were now available to potential customers. The N5 process can use EUVL on up to 14 layers, compared to only 5 …

Aug 12, 2024 · Extreme ultraviolet (EUV) lithography is the leading lithography technique in CMOS mass production, moving towards the sub-10 nm half-pitch (HP) regime with the ongoing development of the next generation high numerical aperture (high NA) EUV scanners.

15 hours ago · The other two EUV exposures are used for cut masks that trim the lines from pitch splitting and also pattern the larger pitch metal features. High-NA replaces all this with a single exposure and many fewer process steps. ... At the 13.5nm wavelength, relatively few photons are emitted by the source, but they are much higher power relative to ...

Jul 8, 2019 · Samsung Foundry has certified full flow tools from Cadence and Synopsys for its 5LPE (5 nm low-power early) process technology that uses extreme ultraviolet lithography (EUV).

EUV process can get pattern fidelity stable, The LCDU value is improve >40% than VSB PCAR process. Low sensitive resist capability is enough for 5nm EUV technology.

Researchers at the Paul Scherrer Institute (PSI) have developed a photo lithography technique to create denser circuit patterns. The current state-of-the-art microchips have conductive tracks separated by 12 nm. The current work enables tracks with a separation of just 5 nm.

Mar 6, 2018 · Semiconductor foundries are pushing ahead with extreme ultraviolet lithography (EUV) integration, but there are still formidable barriers to deploying the technology at 5nm and below.

This paper presents a minimum pitch single patterning process for 5nm node back-end-of-line (BEOL) integration based on extreme ultraviolet (EUV) lithography with quasar illumination and optical proximity correction (OPC).

Apr 16, 2019 · Samsung’s 5nm is the next step in the evolution of EUV. 5nm will be more efficient and feature new innovations including Samsung’s proprietary Smart Diffusion Break (SDB) transistor architecture.
