Euv laser

The tool consists of a laser -driven tin (Sn) plasma light source, reflective optics comprising multilayer mirrors, contained within a hydrogen gas ambient. The hydrogen is used for keeping the EUV collector mirror in the source free of Sn deposition. EUVL is a significant departure from the deep ultraviolet lithography standard.

EUV Mask Defects Advances in EUV source generation bring. Among all the unsolved technological challenges the generation of appropriate light has been biggest.

For a long time, there was severe doubt if the target of 2Watts for high volume manufacturing could ever be . It allows exposure of fine circuit patterns with a half-pitch below nm that cannot be exposed by the conventional optical lithography using an ArF excimer laser. Putting it into practical use requires a variety of element . Everyone agrees that existing ArF laser (argon fluoride) immersion lithography will only reach smaller process nodes through an increasingly difficult manufacturing process that increases costs and makes it impossible, in the long term, to push . Mar One of fundamental aims of extreme ultraviolet ( EUV ) lithography is to maximize brightness or conversion efficiency of laser energy to radiation at specific wavelengths from laser produced plasmas (LPPs) of specific elements for matching to available multilayer optical systems. Tin LPPs have been chosen . EUV Source Candidates for Clean, Collectable.

Our laser produced plasma technology enables manufacturing of nano-scale devices. Discharge-produced plasma (DPP) and laser -produced plasma (LPP) are the leading technologies for generating high-power EUV radiation at 13. In both technologies, hot plasma of ≈20–eV of the chosen fuel material is generate which produces EUV radiation. In DPP, magnetic pinching of low-temperature.

We describe a laser -plasma source based on a cryogenic xenon liquid-jet target suitable for extreme ultraviolet ( EUV ) projection lithography. EUV lithography is used for .

Recent improvements in the stability of the xenon jet allows efficient laser -plasma operation several millimeters away from the nozzle orifice.
