What is argon fluoride?
Abstract. Argon fluoride (ArF) is currently the shortest wavelength laser that can credibly scale to the energy and power required for high gain inertial fusion.
What is ArF lithography?
Chipmakers are extending leading-edge deep ultraviolet (DUV) argon fluoride (ArF) immersion lithography to address device nodes down to 10 nm. This has been made possible by implementing increasingly complex techniques in order to compensate for the physical limitations of optical printing.
What is ArF immersion?
ArF (argon fluoride) immersion light sources feature a 193 nm wavelength for patterning critical layers during IC production and for multi-patterning applications that support the world’s most advanced semiconductor production nodes.
How is ArF laser produced?
Excimer lasers are light pulse-emitting gas lasers, forming an excited dimer by an electric discharge of a gas mixture containing an inert gas and a halogen gas that produces a molecule ArF⁎ that exists only in the excited state (⁎) with life times of the order of 20ns.
What is argon Fluorohydride used for?
Stable only at very low temperatures, argon fluorohydride begins to decompose once it warms above -246°C (-411°F). Because of this limitation, argon fluorohydride has no uses outside of basic scientific research. It is used in electric light bulbs and in fluorescent tubes at a pressure of about 400 Pa.
What are argon lasers used for?
Argon laser treatment can be used to treat a number of eye conditions including glaucoma, diabetic eye disease and some retinal holes and tears. It can also be used to prevent an eye condition from getting worse, and sometimes to cure it.
What is krypton fluoride used for?
Apart from photolithography, krypton fluoride lasers are used in nuclear fusion energy research, production of soft X-ray emissions, micromachining of plastics, composite materials, and organic tissues. Since the krypton fluoride laser emits deep ultraviolet radiation it is used in medical surgery and therapy.
What is DUV and EUV?
– DUV: Deep ultraviolet, a wavelength range in the far ultraviolet. Chip production uses 248 and 193 nanometres. – EUV: Extreme ultraviolet, the wavelength range between roughly 100 and 10 nanometres.
What does immersion lithography do to DOF?
In other words, for a given feature being printed and a given numerical aperture, immersion lithography will provide a greater depth of focus (DOF).
How does ArF laser work?
The UV light from an ArF laser is well absorbed by biological matter and organic compounds. Rather than burning or cutting material, the ArF laser dissociates the molecular bonds of the surface tissue, which disintegrates into the air in a tightly controlled manner through ablation rather than burning.
What is argon Fluorohydride made of?
Argon fluorohydride (systematically named fluoridohydridoargon) or argon hydrofluoride is an inorganic compound with the chemical formula HArF (also written ArHF). It is a compound of the chemical element argon….Argon fluorohydride.

What are 5 uses for argon?
Uses of Argon
- Radioisotope Dating. It can be useful along with potassium, and K.
- Shield Gas in Welding. We also use it for the purpose of welding of specialty alloys.
- Heat Treating. As an inert gas, we can use it can to give oxygen- and nitrogen-free setting for heat-treating procedures.
- 3-D Printing.
- Metal Production.
How much does an argon laser cost?
How Much Does Laser – Argon Cost? The prices of some systems can be as low as 500 USD or less, while the newest, high-tier systems may cost as much as 30.000 USD.
How is krypton fluoride made?
It consists of two elements, krypton and fluorine, as the lasing medium. The principle behind the working of the laser is that krypton absorbs energy from the power source and reacts with fluorine gas to produce krypton fluoride, a temporary complex.
What is KrF lithography?
A krypton fluoride laser (KrF laser) is a particular type of excimer laser, which is sometimes (more correctly) called an exciplex laser.
Is EUV better than DUV?
Creating EUV light EUV lithography, a technology entirely unique to ASML, uses light with a wavelength of 13.5 nanometers. This wavelength is more than 14 times shorter than DUV light.
