Witryna22 mar 2007 · The immersion technique was first introduced by Carl Zeiss in the 1880s to increase the resolving power of the optical microscope. Introduction of the immersion technique into modern lithography was suggested in the 1980s. It attracted the IC industry's attention in 2002 when 157nm lithography was delayed by several … Witryna26 paź 2024 · Immersion lithography improves lithography resolution by increasing the NA, or "numerical aperture".

WitrynaImmersion lithography is now in use and is expected to allow lenses to be made with numerical apertures greater than 1.0. Lenses with NAs above 1.2 or 1.3 seem likely. If an immersion fluid with a refractive index closer to that of the photoresist can be found, numerical apertures of up to 1.5 might be possible.

EUVL technology is an advanced technology with a light source of 13.5 nm, which is extremely short wavelength and can be applied for beyond the 10 nm node. EUVL enables the use of only one mask exposure instead of multiexposure.

Witryna5 paź 2024 · Description. Extreme ultraviolet (EUV) lithography is a soft X-ray technology, which has a wavelength of 13.5nm. Today’s EUV scanners enable resolutions down to 22nm half-pitch. In a system, an EUV light source makes use of a high power laser to create a plasma. This, in turn, helps emit a short wavelength light …
