What is an Excimer Laser Gas Mixture?

Excimer laser gas mixtures are specialized blends of noble gases (e.g., krypton, argon, xenon) and reactive halogen gases (e.g., fluorine, chlorine) that generate pulsed ultraviolet (UV) light when electrically excited. These precise formulations enable cutting-edge applications from semiconductor manufacturing to corneal surgery.

Key Components:

• Base Gases: Kr (Krypton), Ar (Argon), Xe (Xenon)
• Halogen Donors: F₂ (Fluorine), Cl₂ (Chlorine)
• Buffer Gases: Ne (Neon), He (Helium)

Top 3 Industrial Applications of Excimer Laser Gas

1. Semiconductor Lithography

• KrF (248nm) & ArF (193nm) Lasers: Dominant in EUV photolithography for <7nm chip fabrication.
• Critical Specs: ≤0.1ppm impurities to prevent wafer defects.

2. Medical LASIK Systems

• XeCl (308nm) Lasers: Used in corneal reshaping with gas purity requirements exceeding USP Class 5.

3. OLED Display Manufacturing

• F₂-Based Mixtures: Etch ultrathin organic layers with 10μm precision.
