After the discovery of excimer lasers in 1982, lamp-based lithography techniques became obsolete. By continuing to browse this site you agree to our use of cookies. Nikolai Basov, Yu. Use of this laser for lithography has not only replaced the use of mercury-xenon lamps, but has also provided much more precise and finer resolution solutions to photolithography techniques. The krypton fluoride (KrF) laser is an excimer laser, which emits deep ultraviolet wavelengths. 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. M. Popov, and V. A. Danilychev invented the excimer laser in 1970 at Lebedev Physical Institute, Moscow. Repetition rates of 250Hz and 500Hz in air cooled units, an average power of 12W with KrF at 248nm and 6.5W with ArF at 193nm give of operation between refills using XeCl.

The laser beam from a KrF excimer laser (Model: Coherent COMPexPro 110) with wavelength 248 nm is focused on the sample by optical arrangement and workpiece movement is achieved by XYZ translational stage (Aerotech Co.,). CVI Laser Optics is An IDEX Optical Technologies Solution. The excimer laser is the powerful light source in the ultraviolet (UV) region of the electromagnetic spectrum. Safety precautions need to be exercised while working with this laser, as it damages the human eye when exposed to the UV radiation. An excimer alternative — not a replacement An applications engineer who was very familiar with both excimer and TEA CO 2 lasers once commented, “If you’ve ever used an Impact TEA CO 2 laser, you’d never look at an excimer again.” That is an overstatement, because there are some applications where excimer lasers are clearly the preferred choice (Table 1). The spectral widths are typically 2 nm. M. Popov, at the Lebedev Physical Institute in Moscow, using a xenon dimer (Xe2) excited by an electron beam to give stimulated emission at 172 nm wavelength. KRF: Excimer Laser Mirror 248nm High power UV excimer laser mirrors for 45° AOI ; ArF (193 nm), KrF (248 nm), or XeCl (308 nm). While electron-beam pumped excimer lasers can produce high single energy pulses, they are generally separated by long time periods (many minutes). The Excimer Laser – Market Leading UV-Technology COMPex lasers are highly efficient light sources, featuring a compact design and easy installation and operation. 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. Excimer lasers, such as XeF and KrF, can also be made slightly tunable using a variety of prism and grating intracavity arrangements. They are built on an electronic transition principle, and the emitted radiation is predominantly in the UV spectral range. A number of microelectronic devices are manufactured by photolithography. These high quality excimer laser mirrors provide high reflectivity, high surface accuracy and quality, and high laser damage threshold for the UV operating wavelengths of ArF, KrF, and XeCl lasers. Excimer lasers are pulsed gas lasers that intrinsically offer efficient and powerful broadband emission at several spectral regions throughout the ultraviolet. The EX10 excimer laser offers state of the art performance in a compact package and provides a highly reliable, powerful source of ultraviolet radiation. An excimer laser typically uses a combination of a noble gas and a reactive gas. These results are in good agreement with the theoretical calculations based on a simple pulse-laser model and the van Cittert–Zernike theorem.
