The XeCl laser serves different systems through two distinct mechanisms: In the cardiovascular field, it employs a “cold ablation” approach to directly vaporize calcified plaques, making it a crucial tool for interventional treatment of severe calcification. In dermatology, the same wavelength of light is specifically absorbed by immune cells involved in disease, enabling precise immunomodulation for the treatment of vitiligo and psoriasis. Ophthalmology utilizes an ArF excimer laser (193 nm), whose “ablation effect” is exceptionally fine; by breaking molecular bonds in the cornea, it facilitates tissue remodeling and forms the cornerstone of procedures such as myopia correction (LASIK). Together, these three applications highlight the therapeutic value of laser medicine—precision, targeting, and efficiency.

Research-oriented

Excimer lasers for scientific research and industrial applications are gas-based laser media used to generate high-power pulsed lasers at specific wavelengths. Their primary function is to produce laser beams with industrial or scientific applications through gas discharge in corresponding devices. The application areas of these laser beams include deep-ultraviolet lithography light sources in chip manufacturing, industrial processing beams for material cutting and surface treatment, and excitation light sources for scientific research. The gas composition, purity, and related technical specifications of these lasers depend on specific performance parameters such as wavelength, output power, and repetition rate, all of which must comply with particular industrial and scientific application standards.

Display panel category

In display panel manufacturing, high-purity gases are critical process materials: argon (Ar), nitrogen (N₂), and helium (He) are used for film deposition and etching environments as well as for protective purposes; fluorine-based (CF₄) and chlorine-based (Cl₂) gases are employed in dry etching processes; photolithography equipment requires a mixed gas of krypton/fluorine/neon (Kr/F₂/Ne) for its light source; and high-purity nitrogen is essential for providing an inert environment during high-temperature processes and packaging stages. The ultra-high purity and stable supply of these gases directly impact the precision, yield, and cost of display panels.

Excimer Lasers and Extreme Ultraviolet Lithography Gases: Core Components of Advanced Semiconductor Manufacturing

In the semiconductor manufacturing field, the continuous miniaturization of devices has directly driven the reliance on advanced lithography technologies. As process nodes continue to shrink, the number of patterning steps required has increased significantly, leading to a corresponding rise in the consumption of excimer laser gases. As the next-generation lithography technology, extreme ultraviolet (EUV) lithography is being developed to further break through physical limitations. This technology indirectly involves the use of carbon dioxide and hydrogen, and it complements existing deep-ultraviolet (DUV) lithography rather than replacing it in the foreseeable future.

Unveiling the Core Consumable of the 308nm Excimer Laser—The Mixed Gas

When we talk about the outstanding performance of 308nm excimer lasers in dermatological treatments—such as vitiligo and psoriasis—or in precision industrial processing, we often focus on their precise energy delivery and remarkable efficacy. But what exactly is the “heart” that powers this sophisticated device to emit that specific ultraviolet light?

What is an excimer laser?

An excimer laser is a type of laser that is generated when an inert gas mixed with a halogen gas is excited by an electron beam, causing the molecules to transition from an excited state back to their ground state and releasing laser light in the process. This laser belongs to the category of cold lasers and features strong directivity, excellent monochromaticity, high peak output power, and pulsed characteristics. Its wavelength range spans from 157 to 353 nanometers, with relatively high photon energy and a lifetime of approximately tens of nanoseconds, placing it in the ultraviolet spectral region. Commonly used wavelengths include 193 nm (ArF), 248 nm (KrF), and 308 nm (XeCl).

What is an excimer laser?

Excimer lasers are a class of gas lasers that operate based on the stimulated transition between energy levels of excimer molecules. The active medium typically consists of transient compounds formed by inert gases and halogen gases in their excited states (such as ArF, KrF, XeCl, etc.). These lasers emit light at wavelengths in the ultraviolet range (157–353 nm) and are characterized by high photon energy, large peak power, and narrow pulse widths (typically tens of nanoseconds). They are currently important high-power coherent light sources in the deep ultraviolet region.
